I have posted so much about the Stache 29+ I've forgotten to post some info about my new Specialized bike.  While technically not a Chiner, the carbon frame was made in Taiwan.  I've got about 60 miles on the bike now and can say I've very happy with my choice.  Comparing the build quality of the Specialized to the Trek, I would easily say the Specialized is a much nicer bike.  This makes sense since the MSRP of the SJ 6Fattie is almost double that of the Stache, $4,500 vs $2,499.  However, Specialized is blowing out this model and knocked off $1,400 of the list price to make room for the 2017 models.

The first thing I notice when riding the SJ is the plush ride.  With 150mm suspension up front and 135mm out back, this is easily the most comfortable bike I've ever ridden.  I haven't had a chance to weigh the SJ yet but I'd say it's around 27-28 lbs, just about the same as my Trek Stache.

The next thing I noticed is how much it rides like a regular FS 29er, you wouldn't know the wheels are 27.5", obviously that's due to the plus tires being similar in overall diameter.  The ride is super-smooth, with the larger volume tires working in concert with the suspension.  Like the Stache, the SJ really swallows up the trail in huge bites.  Also like the Stache, the riding position makes you feel as though your CG isn't high on the bike, instead you feel like you are lower than you are.  It's a bike you could ride all day and not get a lot of fatigue.  My last ride was 18 miles and while I was tired, no part of my body felt like it was beat up from the trails.

There is extra grip from the 27.5+ tires but it's not nearly the grip of the 29+ tires.  On the other hand, the rear grip under braking might be a little better given the rear suspension works very well to keep the rear tire in contact with the ground.  The bike tends to squat under hard braking rather than transferring weight off the back wheel like a hardtail might.

Some of the niceties that you get with the SJ is a high quality finish on the frame, much higher stiffness of the rear suspension compared to my -036.  Also with the increased travel over my -036, I can really feel that FSR suspension is working, it's very active, so much so I can leave it in the firmer mode and still get plenty of travel on the trails I ride.  You also get the SWAT storage compartment and multi-tool storage above the shock.  The tool didn't come with the bike, that was another $30, but it's so easy to grab, I find myself doing quick adjustments when I stop and catch my breath from that last big uphill.

Negatives are few.  The bottom bracket is slightly lower than the Stache, possibly a bit lower than the -036 but not by much.  Which is the cause of a few unexpected pedal strikes.  Not terrible by any measure but noticeable.  The seat stays are wide, like the Stache, my calves don't rub them and they are not annoying, but when coasting I feel there is not much clearance between me and the frame.

When riding the 29+ and 27.5+ back to back, I still have to say the Stache is the more playful, fun-to-ride bike, but the SJ is the do-it-all, take-it-anywhere type of bike.

Vendor Discussion & Reviews / Bicycle Companies Selling Chiner Bikes
« on: August 09, 2016, 08:30:00 PM »
I am starting to run across more and more companies selling bikes with the same frames as forum members buy direct from China and build up themselves. 

It's interesting to see, however, some companies make false claims about where the frames come from.  For example, the person from Deep South (not sure if it was the owner) claimed they make their own carbon frames.

Deep South (USA)
http://www.deepsouthbicyclecompany.com
Not much of a website with pictures of the Chiner drawings of "their own" frames. They do offer a "Lifetime" warranty although I would guess the lifetime of the company might be shorter than the time you own your bike from them.  Although, since they charge about double for the frame, even if you break one and have it replaced under warranty, they are not out anything.

Lamere Cycles (USA)
http://www.lamerecycles.com
At least Lamere is up front that they "import carbon frames and rims directly from the top factories in Asia."  Although notice they say "Asia" and not "China."  Lamere also offers a "lifetime warranty".  They charge about 2-3 times for a CS-036 or a CS-057 frame compared to what Peter charges.  This company has been around for about 3 1/2 years now so at least they have stayed in business for a short while.

Olympia Bikes (Italy)
http://www.olympiacicli.it/en/
They seem to carry a variety of bikes, and their website looks very professional.  They don't seem to sell direct but instead appear to have a dealer network.   In a previous thread, someone else commented that they have been around for many years.  They make the CS-M04 look really nice.  They don't say anything about warranty and don't have any dealers in the US.  I would expect their pricing to be similar to other big brands.

Pricepoint (USA)
(Out of Business)
PricePoint was another one, they would sell Sette carbon frames which looked just like the CS-057 but had a 5 year warranty.  Another case where the warranty doesn't do much good if the company is no longer in business.

Pells (Czech Republic)
http://www.pells.eu/en/bikes/full-suspension-29/f99-xx/rok-2014/
Nice website.  Above link is to a -036 complete bike.

Kelly's Bikes (Slovakia)
http://www.kellysbike.com/INT/bikes-2016/mountain/hardtail-29/stage-90#.V6sNB2XSdE4
5 Year Warranty.  Website does not show pricing.

Superior Bikes (UK)
https://superiorbikes.eu/en/2016/mtb-race/team-29-issue/black-red-white
They claim, "All key manufacturing processes are implemented internally so that we have the best control over the design, construction, painting, wheel building and assembly of our models."  Which sure sounds like they are saying they manufacture their own bikes.

I will update the top of this thread as we find more online bike company startups selling Chiner frames/bikes direct.

Sales & Classifieds / IP-036/IP-057 Replacement Hangers
« on: August 05, 2016, 01:47:03 PM »
After selling my Chiner bikes I found I still have three sets of spare derailleur hangers that I no longer need.

If anyone in the US wants a spare I will ship one to you $15, or if you want all three $30.

Two of them are two piece designs, one is a one piece design, same thing just a little different.  The two different designs are interchangeable.

29+ & 27+ / Before & After
« on: July 23, 2016, 09:24:28 PM »
I'm sure I will build another Chiner of some sort in the future, but for now I am back on a couple branded bikes again.  I do miss having a bike that I hand selected each and every part but both of my new bikes work really well for the trails I ride.  After selling both my Chinese carbon bikes and getting decent deals on the two new bike, I have been able to minimize the expense buying of two new bikes.  The Trek Stache 7 was discounted 17% off MSRP, and the Specialized was discounted 31% off MSRP.

BEFORE: Chinese Carbon 29ers



AFTER: Specialized Carbon 27.5+ and Trek Stache 29+

29+ & 27+ / What to build next?
« on: July 02, 2016, 07:35:48 PM »
Okay guys, looks like I've got my IP/CS-057 sold.  The buyer has committed to buying it but only after I install my GX drivetrain from my Trek Stache.  I'm happy to change out the parts and sell the bike a little cheaper since it will be an upgrade to the Trek.  One minor bump in the road is the Stache has Boost spacing on the chainring (+3mm offset) while the -057 has the standard zero offset.  Not a big deal, I just ordered two chainrings to make the swap and have the correct chain lines.

Once I get everything changed over I have a new problem to solve, what to do next?

I'm looking at either building a 27.5+ full suspension bike using the XMCarbonSpeed CS-M04 http://xmcarbonspeed.com/Productinfo.asp?f=1438




Or go off-the-shelf again and buy a Specialized Stumpjumper 6Fattie https://www.specialized.com/us/en/bikes/mountain/trail/stumpjumper-fsr-comp-6fattie/107081



If I go with the Specialized bike, I think I will be ban from Chinertown as I will no longer own any Chinese carbon whatsoever!  Bummer.

Pretty much no carbon of any kind at that point.  However, I've learned that a carbon frame is getting to be less important with plus tires as the extra air volume smooths out the ride more than the frame material ever did.

29er / 29er/29er+ Picture Overaly
« on: June 21, 2016, 07:11:18 PM »
So I thought I would try overlaying a picture of my -057 and Stache to get a visual of how different the bikes are and if there was something I could do on the -057 to make it more comfortable like the Stache is for me.

I aligned the center axle of the crank in Photoshop.  What surprised me was how the seat heights were nearly identical even though the seat feels a bit lower on the Stache.



Here is another version of the same picture with a filter applied:

Component Deals & Selection / New System for Tubeless Sealant
« on: June 01, 2016, 10:58:13 AM »
I just saw this and am fairly impressed.  MilKit has taken a hard look at the tubeless mountain bike tire and how to best manage adding sealant.   They say the system is available in the US through Amazon.

29+ & 27+ / New CarbonSpeed 27.5+/29+ Frame (CS-496)
« on: May 09, 2016, 06:17:29 AM »
Peter is calling this one the CS-496.  Looks nice.  If this were available a few weeks ago, I may have decided to build a bike with this frame instead of buying the Trek that I have.

29+ & 27+ / Trek Stache 7 First Ride
« on: April 30, 2016, 10:49:53 AM »
Picked up my 29er+ bike yesterday.  I came close to purchasing a Workswell WCB-M-078 Chinese carbon frame, which is a close copy of the Stache, but in the end decided to give the Trek a chance.  Since I was able to do some demo rides at the trails before purchasing, I was able to know how the bike rides before shelling out the cash for another bike.  I wouldn't think the Workswell bike would be very much different, but not having the opportunity to ride one, I stuck with what I knew.  When looking at the purchase from a cost value point of view, the Stache 7 hit a pretty good sweet spot, after the discount the purchase price was $2,160.  I could not build a Workswell bike for that, and I liked that I could get the bike quicker and start riding it this week.

Ride Report
As I have discussed in other posts, the ride a 29+ bike offers is not like anything else.  The bike rolls super smooth and when it comes to rooty, rocky sections of the trail, you just pick a straight line and roll over anything in your path.  Unlike my "skinny" tire bikes, rolling over roots and rocks just doesn't slow you down much at all.  I don't find myself weaving around on the trail dodging obstacles because I don't need to.

Another noticeable difference with the big tires is over loose downhill gravel road sections.  Where my 2.4" tires would slide around and not give me much confidence that I wouldn't wash out and have a bad day, the big plus tires grip the loose stuff and allow me to go faster with no nervousness.  Truly confidence inspiring.

In tight sections, the Stache felt great, very maneuverable in the tight bends and around trees.  I just can't find much fault with this new big tire size.  No tire squirm like on a fat bike.

Towards the end of the ride I met up with two guys, one on a 29er full suspension, he's 15 years younger than me and in much better shape.  I not only caught him on a long uphill gravel climb, when the trail turned and got really fast, I stayed right with him.  I had no room to pass so I stayed close behind until I just plain ran out of breath keeping up with him.  I think the bike, with it's immense amount of grip, allowed me to carry speed into corners that he couldn't.  It was a blast following someone else on this bike through fast trail sections, knowing I had so much more grip than he did.  Again, very confidence inspiring.  All I can say is if anyone has the opportunity to ride one of these, give it a try, you may end up liking it as much as I do.

I need to get the tubes out, the bike shop said they would have done it for me but the new Chupacabra tires can be difficult to air up tubeless until they have had a few rides on them.  The Sun Ringle Mulefut rims come tubeless ready with valve stems.  Each tube weighs like a pound so that will help get the bike down to 28 lbs easily.

I've talked with Peter about getting some 50mm carbon 29er wheels with DT Swiss hubs but am undecided if I want to spend the money right now or consider getting a set of 40mm x 27.5" wheels to try with some 2.8" tires like Patrick and Sportinggoods have done.

I'm off now to take the Stache on a second ride this afternoon.  So far, I'm lovin' this bike.  Here are a few pics from yesterday:

The big tires barely fit on my bike rack.  I can barely close the hold down straps around each of the tires.


On the trail.

29+ & 27+ / Rode a 29+ Trek Stache
« on: April 11, 2016, 12:45:05 PM »


We had a bicycle demo at the local trail over the weekend, funny part was it was a Santa Cruz demo, not a Trek Demo.  However, one of the other guys showed up to the event with his Trek Stache 9 (29er+) and let me ride it while he did a demo ride on a Santa Cruz Hightower 27.5+ bike.  We rode a 10 mile loop, about an hours worth of riding.

The Stache was so much fun I am not seriously considering building up a Chinese 29+ hardtail for myself!

The Stache had the Bontrager Chupacabra tires that just gripped so well it was nothing short of inspiring.  I could take any line, bumpy or smooth, through a turn and it just didn't matter, the tires soaked up the rocks and roots.  The bike made the trail feel 50% smoother.  On the flat stuff the bike also felt very smooth, the tires even hummed along like an off road truck tire does on the street.  I've never "heard" my tires rolling along in the dirt on any other bike I've ridden.  The tires were dialed in at 14psi and worked very well at that pressure.  I'm sure if I added a bit more pressure it might feel different, maybe quieter.

The bike felt very maneuverable, not that much different than my 29er with 2.4" tires.  To me, it rarely felt like I was on a bike with 29"x3.0" tires.  I just felt like I was on a 29er that had tons of grip.  Loose sand, no problem.  Muddy spots, no problem.  The tires never slipped.  The only time you would feel anything is if you were turning just slightly at speed, that's when you feel a bit of angular momentum or gyroscopic effect from the bigger wheels.  I'm sure a set of carbon wheels would decrease that a bit as well.  The owner told me he weighed the Chupacabra tires and they were less than 900gr each.  He also said they don't wear fast, 1700 miles and still looked like they had 50% remaining which is good since they are a $120 tire.

There were two faults I would post about this bike.  One is the fork.  I'm not a fork snob, to me as long as it soaks up bumps any fork is fine.  However, the Manitou Magnum Pro fork was not very good.  On big hits it was just jarring, it did fine on small to medium bumps but the larger hits or small drops is where this fork is lacking.  If I were to build a bike, I would not choose this fork.

The second thing, and it's not really a fault, is the rear seat stays were wide enough that I could feel my calves lightly rubbing against them.  I could also feel the seat stays when coasting, I would kind of rest my leg against them.  It's not like my shoe heal was hitting the frame which would be a deal breaker.  This wasn't too bothersome, I think it's something that I could easily live with, but it was worth noting.

The frame was a 20.5" (XL) and I thought it would feel big but it didn't, it felt similar to my 19" -057.  The owner of the bike did say he changed out the stem to a 50mm one and put on carbon riser bars.  I'm 5'-11" so it made me wonder why it did not feel like an even bigger bike.  However, if you read the size chart on Trek's website, the Stache does have funny sizing.  I may get the chance to ride a Large Stache 8 this Friday as another guy from a local bike shop said he would bring one up to the trail for me to try out.

After riding the Trek Stache 9, I rode the Santa Cruz HighTower 27.5+ bike.  I was ready to give the bike back after just 10 min of riding.  It just didn't have half the fun factor for me.  However, the owner of the Trek Stache loved riding the HighTower and is seriously thinking of buying one.  To each his own I guess.

Vendor Discussion & Reviews / MTBR Forums Hacked
« on: April 08, 2016, 08:51:15 AM »
Looks like anything you click on in the Forums section on MTBR opens a new window for a online reseller.  Seems like the forums got hacked.  I tried two different browsers, same problem.  Hopefully something like this can't or won't happen to ChinerTown.

In the meantime, we might see a jump in the amount of traffic coming here if MTBR is essentially down.

Chain Reaction is selling what looks to be a -057 frame with nicely spec'd components for $2049.  This is quite a bit less than what I built my CS-057 XT/XX1 for a few years ago and probably less than what I could build it for today.

I am very happy with my 1x11 XX1 but now SRAM has taken 1x to the next level.  Another step toward obsolescence of the front derailleur.
