Anyone have issues with a knocking noise coming from the rear shock? I've swapped to a different shock, so it's not the shock itself, but using the same Fox hardware on both the Fox DPS and Manitou Mara Inline. The noise seems to go away when reinstalling the shock, and then will return after a few rides, which makes me think the shock hardware is the cause, and not a linkage or something else. It seems to happen on top-out, primarily down repeated root hits. Maybe the hardware is undersized and I just need a new set of hardware?

Cyclocross Frames, Wheels & Components / Re: ZTTO 11-46 cassette 11 speed
« on: September 22, 2021, 08:02:51 AM »
You are correct in the road world, 11 speed cassettes got wider and thus a longer freehub and 10 speed cassettes would need a spacer.  In the MTB world, 11 and 12 speed HG cassettes have the large cogs pinned together and the large cogs kind of sit over the inside end of the freehub, so it packs 11 or 12 cogs in the same 8/9/10 speed freehub.  Now that road groupsets are coming with wider range cassettes it gets a bit foggy, because the 11-28 to 11-32 cassettes are road, and 11-42+ are MTB (even if they come in a road groupset), not sure about mid range like an 11-36.

Yes, the Markhor is a good match for the bike and is a very good fork for the price

Strange the DAIRSBIKE Store person told me that I will need Novatek NT-d462 rear hub if I want 12speed cassette   
There's certainly a lot of confusion when it comes to freehubs.  The number of gears doesn't matter, the specific cassette does.  The older and more typical freehub (Shimano HG) works for all cassettes that use a freehub (so not old 7 speed freewheel cassettes) that use an 11t small cog.  So all 8/9/10 speed, and 11/12 speed cassettes that use an 11t small cog.  This includes SRAM NX 11 and 12 speed, and aftermarket cassettes like Sunrace.  The SRAM XD driver is used for SRAM 11/12 speed cassettes that use a 10t small cog, and aftermarket cassettes like E13.  The Shimano Microspline is used for Shimano HG+ cassettes, which is all of their 12 speeds.  The HG+ has a new updated tooth profile that's beneficial, so if your budget can accommodate, then it'd be worth finding a Shimano 12 speed cassette and Microspline freehub.  Not the end of the world if you stick with that groupset with Sunrace cassette and use an HG freehub.

For the frame where the fork will be they specify L=500mm
For that fork they specify 555mm. Minus 30% sag means 513mm
So my front of the bike will be probably around 10mm higher
Do you believe this is an issue?

Geo charts list extended A2C.  So the fork you specified is 55mm longer than desired.  That is too tall, will compromise geometry, and can have catastrophic results with the frame.  I would personally try to find a used fork from a name brand, those generic forks just don't have quality damping, similar to a low end Suntour.

What do you guys think about the brakes.
A friend of mine told me that 160mm front and rear disks may be too small?

Thanks     
I use 160mm front and rear on my XC bike.  For my longer travel bike and aggressive hardtail, I prefer 200mm front and 180mm rear.  It's all preference.  It's not much weight gain to use larger rotors, so if you are going to be doing big downhills then it's worth it for the heat capacity.

I used ABS to print mine, but I've used PETG on some for friends since I'm able to print it better.  I've used mine for about 800 miles and it's holding up great.

I've only tried that mount on a GG Trail Pistol with the bottle cages hanging down from the top tube, haven't tried with a bike on the downtube.  It was wide enough that my knees were constantly hitting the bottles.  It also looks real silly, but some may not care about that.

I think the best solution is using a mount to stuff two bottles in the triangle.  I used Lyne Components for inspiration (because I wouldn't pay this much for just a mount) https://www.on-lynecomponents.com/collections/the-holy-rail/products/holy-rail-dual-cage-kit and I 3D printed my own bracket.  It's about 100g if I remember right, super stiff, and I can design it fit the frame perfectly.  Here's a picture mounted on my LCFS911, not too easy to see in that picture but it shows the concept.  The mount shifts the forward bottle cage up one bolt hole, so if you mount a cage on the FM936 using just the top hole and it fits, and then if you can hold a bottle between that and the shock, I should be able to make a mount that will fit.  I've also got a 1:1 PDF of the mount that you could cut out and see if it fits without modification.

https://www.mtbdirect.com.au/how-to-measure-the-shock-and-hardware-size-on-a-mountain-bike

There's a writeup and picture in this article about trunnion mounts.  Standard shocks use an eyelet at either end of the shock.  These eyelets require purchasing hardware to fit the frame on both sides.  A trunnion mount is basically two threaded holes on either side of the shock body.  There will be bearings in the frame or linkage, and frames will come with the bolts that go through them, so you will only need to purchase hardware for the one eyelet mount on the other side of the trunnion mount.  I believe the FM936, ICAN S3, and LCFS911 all use trunnion shocks.

Have you ridden full-suspension bikes before?  If not, have you ridden both XC and trail hardtails?  Do you have an idea of what geometry you'd want?  The FM909, FM936, and S3 that Schumo mentioned have great reviews, they're super light, fast, and aggressive.  They are pretty progressive geometry, though, which can be good or bad depending on your preferences.  They will have a longer reach, steeper seat tube angle, and slacker head tube angle than your average XC bike (although the newest name-brand XC bikes are starting to go that way too).  I have an LCFS911 that I really really like.  It's boost, moderately aggressive (kind of in between FM936 and typical old-school XC geo), and pretty light.  It's maybe 100-300g heavier than some of the other XC frames, but mine came in at 23.2 lbs with a moderate build kit.

As far as the rear shock, just get a shock that matches the eye-to-eye and stroke that the frame takes.  There's regular eyelet and trunnion mounting styles, too.  I personally am a fan of Manitous, so I run a McLeod on one bike and Mara on the other.  Most Chinese direct frames don't come with a shock, and I believe some may come with hardware.  The hardware is usually listed on the specs page, for example my LCFS911 uses M8x22.2mm hardware, so just purchase hardware of that size.

Did you all contacted ZTTO?
By their official shop on Ali, is a way.
They seem to care about their customers.
I did contact them, just need to get around to trying to video the hub skipping to show them proof.  I have had good luck with them for returns and such before.

I've got about 700 miles on my M1 hubs and they've started skipping pretty bad.  I opened them up and didn't see anything to note on the ratchets.  I may try to clean them up, re-grease, and see if they still skip.  But I'm more than likely going to find a 36T replacement.  Just trying to decide whether to stay off-brand or go with DT branded parts.

I use this frame for my gravel bike, the version made for 29x2.35 tires.  I use a 38t chainring with no issues, may even be able to go up to 40t.

I did what you mentioned, 29er frame/fork with drop bars.  To be honest I don't ride it enough to give a good review on the setup, but that's not because I don't like the bike, I just ride trails 99% of the time that I don't want to ride rigid.  Thought I'd ride gravel more than I do.

Just did the final shakedown. Very happy with the feel and power delivery.
Specs:
Fox shock (Trek Top Fuel Takeoff)
SRAM XX crankset + Quarq Power Meter
XO1 AXS Eagle 12 speed mini Group
SRAM Level TLM brakes
Amazon $20 disc rotors (fantastic)
Light Bicycle RD934-TR Carbon rims
Profile racing Hubs (USA made)
EThirteen 9-46 12 speed cassette
Following parts from Scott Spark takeoff:
Rockshox Sid 100mm fork Boost
Syncros Carbon Seatpost, Bars, stem
24.5lbs with pedals & Wahoo mounted
Size 19”
Took approx 2 months from order (Nov 20, 2020) to delivery
About $3500 invested combination of new and used parts
I've got this frame now!  1950detroit sold me the frame, fork, shock, handlebars, stem (I swapped to 80mm Syncros stem instead of his 120mm stem), seatpost, and saddle.  I had most of the parts laying around, just had to buy a crank, chain, and a few little parts.

Specs:
Fox shock (Trek Top Fuel Takeoff)
SRAM XO GXP crankset (started it's life as a 2x, swapped on a 32t ring)
11-speed GX derailleur, XX1 shifter, X01 cassette, XX1 chain
Formula Cura 2 brakes
Amazon $20 disc rotors
Speedsafe rims, ZTTO 54t hubs, Pillar Wing 20 spokes, Sapim brass spokes (I built them)
Vittoria Mezcal XC 29x2.25 (I'm curious to try a Barzo front)
Following parts from Scott Spark takeoff:
Rockshox Sid 100mm fork Boost
Syncros Carbon Seatpost, Bars, stem, saddle, grips
Bontrager comp pedals

Build ended up at 23.2 lbs with pedals, and 23.6 with dual bottle cage.  I 3d printed the bracket to hold both cages at the perfect angle, could maybe make an aluminum version that's lighter, but I'm not worried about it, the bracket itself is around 100g and the ABS part seems plenty strong.  First ride was a success, the bike was really fast, it's about 1 lb lighter than my hardtail so having a lighter bike with the sting taken off the rear end was nice.  I only felt any noticeable bob when standing and pedaling hard, and it's nothing major.  The noise I heard was the topping out of the DPS shock, but I think I need to add rebound damping and soften the air spring.  I added McMaster neoprene foam around the cables so those are silent, which is really nice!  I'm hoping this bike will be the perfect XC and long distance bike.  My favorite ride is a 57 miler with 18 miles of very rooty old-school singletrack, 21 miles of flow trail, and the rest is gravel to get in between.  My hardtail makes my joints ache by the end and my trail bike is just so heavy.  The goal of this bike is to cut the difference.  I think my biggest surprise was how nimble the bike was.  My hardtail is a Transition Vanquish, which is 67 HTA (which should match the 911 HTA once sagged), 75 STA, short chainstays, but the LCFS911 feels SO much more nimble around tight turns.

29er / Re: New to China Carbon - horror stories true, or overblown myths?
« on: March 25, 2021, 12:49:57 PM »
From what I've witnessed, the majority of issues with the bikes are things like headset seats not being machined perfectly, BB area needing some smoothing to fit right, these kind of issues take some mechanical competence and being able to identify and fix these types of issues will prevent failure down the road.  I don't see many catastrophic failures very often, like cracked frames, but they do happen.  From reading Chinertown and MTBR everyday, I don't feel that the reports of generic frames cracking are much more frequent than name brand carbon frames.  There are also brands that seem ahead of the curve for quality and customer service, like Carbonada or Ican (many more that you'll find on this site).  They both manufacture frames for name brands, they know what they're doing.

My personal opinion is that a good majority of people who have a bad experience will report it online, and only a small portion of people who have a good experience will report it.  If you go to a thread for a specific frame and find 20 people with good experiences, 1 person with a fitment issue, and 1 person with a crack, then I would be willing to bet that there are 100 more people who had no issues and did not post about it.  I'm also fairly light (160 lbs dry) and don't have much concern riding generic frames and wheels.

How do you find the fork? Thinking of buying one for an xc build
Can't comment on that, I put it on a friends bike.  He's given good feedback, but it's his first air fork so doesn't have anything quality to compare to.  He just dropped the bike off for yearly service yesterday, so I'm curious to pull the lowers and check it out.
