Component Deals & Selection / Re: Wider carbon saddles
« on: February 26, 2017, 10:32:33 AM »
This one from Backcountry is in my list. They have 133, 145, and 155 widths. $170 marked down to $32 is tough to beat especially considering you have Backcountry's warranty and support.

Here is another popular saddle. Ergon SR3 carbon retailing at $249 marked down to $60. Nashbar is always having 25% off coupons so you might be able to get it cheaper. The large is in stock and measures 155.

Thanks for the links, Backcountry wants 60$ in shipping alone so that is out of the question. Nashbar is more interesting but the saddle will still end up in around 100$ as I will have to pay import tax/customs fee etc. From USA it is around 34% of the total cost including shipping. China is better as they typically slips under the custom radar and are much cheaper with free shipping :D

I can get a Specialized Toupe Pro for the same as the Nashbar saddle so if no Chinese saddles are available, I will properly go for this: https://www.cyclestore.co.uk/productDetails.asp?productID=58849

Component Deals & Selection / Wider carbon saddles

Hello All

I have been fighting a sore bum when on longer rides and I finally took the time to sit on the "funny" chair in order to have my sit bones measured. It turns out that I have a rather big distance between sit bones(142 mm) and therefore basically I can now throw out all the saddles that I have as they all are around 135 mm wide. Now I have been crawling around Ebay/Aliexpress and I have not been able to find carbon saddles wider than around 145 mm and I need at least 155 mm. Do anyone knows a vendor that are selling wider carbon saddles ?

I know that Specialized/S-Works are selling their premium saddles in different sizes but would like to try a cheaper option before I invest in a 200+$ saddle.

Thanks

Done and good luck for her :D

I made out pretty good. The wife got me a Reverb Stealth for my 5010 and some Haven 35 carbon bars for my WW062 singlespeed. And I fell for Steep&Cheaps marketing and bought myself last years SC 5010v2 frame at 40% off.

How was St Thomas? St Thomas / St John is on our short list for a July 2017 vacation with the kids. Maui is on the list too as I lived there for 2.5 years before having kids. Other than airfare, Maui can be done rather inexpensive.

Just a side note; these islands used to be Danish until 100 years ago. Denmark sold them to the USA, however in the contract there is a option for Denmark to buy them back after 100 years..... I don't think we will do that unfortunately  ;D

29er / Re: Design flaw/quality issue IP-036
« on: December 29, 2016, 01:28:46 AM »
Im thinking of getting a 036 soon. Which bolts did you end up buying? And

Thanks. It is strange that nobody had this issue before.
I just ordered a 036 for my brother, so I'll order this with all the pieces, and return it if not needed.

Did you need the new bolts? Was the frame bolts still too small?

If you are not a very light person or if you ride the 036 like it is intended to be - You should reconsider your choice of frame. In my opinion the flex in the rear triangle is just too much.

29er / Re: Changing the pivot bolts on the 036
« on: December 28, 2016, 01:18:05 AM »
Did someone changed the bolts of the pivots that came with their 036 frame?
If so do you have the references?

I checked my brother's bike today, as he had a very poor shifting with his Eagle drive train.
The surprising reason was the chain was cut just too small.
And when the derailleur was moving to the smaller sprocket, a piece of the derailleur itself was touching just a little the top pulley and prevented it shifting easily.
Now with two links more, the derailleur presents another angle when coming to the smaller sprocket and shifts perfect as expected.

But then I checked the pivot bolts, and they were almost all loose( bad me, I didn't check them after receiving the frame... )
Luckily none of them was lost.
I re-tightened them all, with some Loctite.
However the hex heads are really poor and I would like to change them.

Hello

I did chance mine as they did not fit, too short and too small in diameter. Long story short, no help at all from Peter so I fixed the issue with buying some bushing bolts mend for mounting rear shocks. They were a bit too long but I shortened them in order to fit. They did reduce my flex issue a bit but it is still far from perfect.

Here is a link to my thread regarding the issue: http://chinertown.com/index.php/topic,906.0.html

29+ & 27+ / Re: 2017 27+ Dengfu FM006 (Scott Spark RC 900)
« on: December 21, 2016, 04:36:44 AM »
Thinking about getting this frame and pulling off parts from my Specialized Fuse 27.5+ hardtail.  Frame looks like a Stumpjumper or Camber from Specialized too.  Very tempting....

I too have been emailing Melody from Deng Fu.  She said the front triangle is the same as their M06 29er frame but with the 27.5+ they have to redesigned the rear.  Waiting on finalized geometry details  to see whether I should pull the trigger or not.

You can't go wrong dealing with Melody from Deng Fu. I just bought a lot of stuff from her and the service was 1. class and reply time was typically within the hour. I bought a carbon road frame and a lot of other parts and it was sent from China to Denmark in 3 days and quality was top notch as well.

Good luck

I haven't found a good way to do HIIT (high intensity interval training) training outdoor. Ideally I'd like to take some of my Zwift FTP-building plan to outdoor rides, but I haven't found a tool to tell me the sequence of the workout while on the bike (apart from a sticky note and a timer). Any advice is appreciated.



You can set up HIIT based training in the Garmin Edge series(520, 820 and 1000) and the cycling computer will guide you through your phases including warm up and cool down.

Hello

I came across a new kickstarter project while reading a "Bikeradar" article - The project basically is able to convert any older system to electric shifting, this could be interesting if shifting turns out to be that much better.

Link to project: https://www.kickstarter.com/projects/1598276649/xshifter-worlds-first-universal-wireless-smart-shi

Link to Bikeradar article: http://www.bikeradar.com/news/article/xshifter-wireless-shifting-48668/?utm_content=bufferec037&utm_medium=social&utm_source=facebook.com&utm_campaign=buffer

After I upgraded both our road bikes to DI2 I must admit that from now on when buying new group sets, I will only look in that direction as I find it so much better under use and so much easier to adjust and maintain.

I've received my Elite Qubo Fluid on Saturday. The equipment is just as I thought: very quiet (the one thing I hear is the sound of my drivetrain, not the trainer), smooth ride. As a premium Strava subscriber I get 2 month free on Zwift. I like it for now. I did a 30 minutes ride on Saturday (rain all day long). It felt short. I did a 45 minutes FTP test on Sunday, felt short again (I wanted a point of reference to track my progress). I feel that 90 minutes ride should be no problem.
Zwift is a lot of fun, the 3D environment is just as good as a real video to me and it's so nice to see "real" virtual people.

The Trainer has no piece of electronics at all (pure fluid roller). I stay on the small ring and get enough range there. I pushed over 600W during the FTP test and can roll easy at 60W for warm up, always in a cadence that is appropriate. I don't need more then that, and if I ever do, I'll just get on the big chainring. That's why I have picked this trainer, you control the resistance through the speed (cadence and gear).


I am probably missing something so be patient with me but I thought Zwift was supposed to be used with so called "smart" trainers to get that close to reality riding feeling (resistance increasing when riding "uphill", decreasing on "downhill" and "drafting" behind other riders. I can't see how your setup could deliver that.
Also, and I am not trying to get into a discussion of "mine is bigger, no way yours so big!", but FTP of 600W seems to be a bit excessive. If I'm not confused Jens Voigt used to have one of 450W. Now, that might have been a full one hour FTP (I am not sure what testing method did you use but most people don't subscribe to the full 60 mins. of torture so I will work with an assumption it was 20 mins.) but even if that was the case and Jens' 20 to 60 minutes FTP drop-off was as high as 50W (unlikely), it would put his 20 min FTP at 500W. In other words yours seems to be 20% better than the former hour record holder's. To me it looks like your testing method might be flawed in a way that would seriously skew your Zwift experience. And don't get me wrong. I don't use Zwift and don't care about any leaderboards there either. Of course it is well possible that those 600W was just a typo and I've wasted my coffee break here.

If SG can push a FTP of 600W he should not be here but on the SKY team - That would be better than Froome and properly close to a world record  ;D

I think that SG mean that he can peak at 600 watts witch I also can but only for less than a minute. My FTP value is a tad past 200 watts and that, based on the BKOOL rating, places me in the highest level of amateurs. As long as your trainer software don't know what resistance you have on your trainer, the numbers you get will always be vague at its best. Speed, HR and cadence are not enough to calculate accurate power numbers if the calculator don't now the power curve of your trainer. I guess that the power curve of the trainer SG have, is known by SWIFT and therefore  able to calculate the power output. A smart trainer I would say is a tad more accurate but also a tad more expensive.

Here is a good article about FTP values between amateurs an PRO's: https://decaironman-training.com/2013/12/09/powerlevels-ftp-pros-vs-humans/comment-page-1/

After reading that, I would say their responses are totally unacceptable and I would never order from them in the future.

I totally agree and they should be confronted by the senior management from this site and if not able to bring a very good excuse/compensation - Immediately banned from this community.

It is borderline fraud in my opinion and if it was me, I would have started a fraud investigation already with Aliexpress.

Reviewing the article it looks like this PowerPod is not a good choice for MTB:

"Finally, one area that doesn’t work well is cobbles.  I recognize this is largely a European problem, and not so much a North American one – but, it’s a valid problem for me since my streets are littered with them.  In my testing, the unit simply doesn’t produce accurate power when riding cobblestones.  Within seconds of hitting such a patch of roadway, the unit pretty much shrugs and gives up.  It’s like this emoticon: ¯\_(ツ)_/¯"

No obvious choice for now...

My primary focus with regards to power meter is my road bike and I agree, it seems like it is not the best option for MTB riding. However I guess it is better than nothing - When spring comes I will try it out on a few rides and come back with some feedback.

Hello

Without doubt I will be riding with a power meter on my road bike next spring, however until now I have been reluctant to pay for a $1000+ solution until I read a DCRainmaker article about the new "PowerPod". Here we are talking a reasonable prizing and according various tests also remarkably accurate compared to the cost.

As a matter of fact quite easy to swap between road- and MTB and I'm just about punch the buy button :)

I think that specific trainer tires are overrated and I know that many people are using their ordinary road tire and that they are as good as any other tire. I just bought the new Michelin Power and did not want to waste them on a trainer winter season so I bought a specific trainer tyre as they were less than half prize of a good quality road tire. For the upcoming winter seasons, I will save my old road tires and use them up on the trainer. So far I have done more than 1000 km on my swalbe trainer tire and it still looks like new.
