« on: December 27, 2021, 03:06:46 PM »OK - I got the stripped bolt out!
Now I just need a replacement. Anyone know what type of bolt it is or where to get one?
TIA,
Ted
OK - I took the stripped bolt to Lowe's and determined that it is a M6x20 bolt. I found a reasonable stainless steel replacement. It has a flat head with the same counter-sink angle (looks like 90 degrees). Only difference is the head diameter is slightly larger, so it won't sit quite flush. Otherwise it looks like it should work just fine.
Hope this helps someone else down the road. Any time we have the suspension apart, it's probably a good idea to look for spare fasteners for the other pivots, too.

Hello all,
Reporting back after building my bike up back in the spring. I've only put ~500 miles on it due to work and alternating rides on my hardtail. I've enjoyed the bike a lot. It does seem to be at its best in high speed sections.
Today I was doing a little maintenance and took the suspension apart for some inspection and cleanup. All the bearings and pivots were still tight and in good condition, so I just cleaned, re-lubed, and put everything back together. However, while tightening the hardware using a torque wrench, I stripped out the head of Torx screw for the rocker pivot. I'm sure it was partly my technique, but perhaps the screw wasn't the highest quality. So I'm currently stuck and in need of two things:
1) advice on how to remove a bolt with a stripped head.
2) help locating a replacement screw of higher quality.
Anyone have any suggestions?
Thanks!
Ted

I'm the same height and went with the large, 120 mm fork, 45 mm stem, and 10 mm riser bar, 780 mm wide. It still feels a bit short compared to my 6 year old large hardtail.
I was also concerned about dropper length, and went with the OneUp 150 mm. I did the calculations and figured I might have to run the collar at the seat clamp or reduce the travel. But as it turns out, I've been able to raise it ~1 - 1.5" above the seat clamp.
So I think there's a good case for going for the large with the OneUp 150 dropper.

« on: April 21, 2021, 11:47:41 AM »Sizing Question
I am 179 CM (5'10.5") and fall right on the line for a M/L. What would you guys suggest? I am coming off a 1995 26' Proflex 855 size large- so zero experience with the modern GEO.
I'm the same exact height and have always ridden larges. (I used to be more like 5'11.5", but apparently I've shrunk.)
Anyway, I went with a large with a short stem (45 mm) and wide bar (780 mm). A medium would have been too small for me. I find myself almost wanting a little longer stem or a setback post. Even though the reach is much longer, the slack head angle and steep seat angle actually makes the saddle-to-bar distance a little less than my 2015 CS-041 hardtail. That bike has old standard geometry.

« on: March 08, 2021, 12:48:21 PM »There is an easy method to work out wheel travel... it is the leverage ratio x the shock travel = wheel travel so to find the leverage ratio we do know that on the specs we have wheel travel is 100mm and shock travel is (165 x)40 so leverage ratio will be 100/40=2.5 so for 42.5 shock travel it will be 42.5x2.5=106.25 - not even 110 unless you can somehow fettle a 45mm stroke shock on there which will give you 112.5
I was hoping to get 120mm travel out of this frame but looks like I'll have to go with either the LCFS937/958 (cracking issues resolved?) or the FM1001 and forgo the flexstay kinematics...
Do those kinematic equations account for the travel due to the flex stays? I could imagine that the flex in the stays might account for some of the difference - maybe 5 - 10 mm?

I ordered a 34T Deckas chainring, too.
Have you been getting updates on your frame? I haven't heard anything since I put in my order two weeks ago. Adam said they had standard weight BSA in stock at the time.

« on: November 23, 2020, 09:27:29 PM »very close to zero, max maybe 4mm or so (from memory). I will measure with my caliper unless anyone can beat me to it.
That would be great - if you can confirm the stack height is <=4 mm, then I think it will work with a low stack height stem (<=30 mm). Head tube length + headset + stem: 120 + 4 + 30 = 154 mm. Steerer tube length = 6" = 152.4 mm.

What's the minimum steerer tube length that will work with this frame? I have a good deal on a Fox Factory 34, but the steerer tube is only 6".
Edit: I should add that I ordered a large with the 120 mm head tube.
Does anyone have the stack height of the headset included with the frame? Is it a zero stack?

« on: November 22, 2020, 10:08:27 AM »These Novatec are really good, I have them on 2 pairs that I ride since 2 and 3 years, and they are always turning smooth.
For spokes, you should try Pillar Xtra 1420 : pretty cheap (around 1€ per spoke), very light, and imo they offer a great reliability to the wheel because they can't twist under tension.
Thanks for the feedback! Where did you order your Novatec hubs and Pillar spokes?

Couple more questions and notes:
Is the consensus to go with 170 cranks on this frame due to the low BB? 175 are a lot easier to find.
I would have preferred BB92, since it has been trouble-free on my two other carbon frames, but BSA was all Adam had available in large standard weight. The good news is that I already have two unused Shimano BSA BB's that came with cranks on my other bikes.
I already have a 740 mm carbon bar and 70, 80, and 90 mm stems. I'm guessing the 70 mm stem would be the best starting point, but might need to go shorter. Any suggestions?
Lastly, I was thinking about trying the Novatec 791/792 hubs due to the low cost. Anyone have experience with them? Alternatively, but for a bit more money, I've had good results with Bitex hubs from BikeHubStore. I always use Sapim Laser spokes.

Hello,
I'm returning to this forum 5 years after my first Chinese- a CS-041 hardtail from CarbonSpeed. That bike is still going strong despite a couple of crashes that required diy carbon repairs.
This time I have been looking for a modern geometry full-suspension frame, and this one looks great. I put in my order with Adam for a large, standard weight with axle, headset, extra derailleur hanger and shipping by sea for a total of $804. I'm 179 cm / 5'10.5" and usually ride a large, so hopefully I will adapt to the fit well.
I'm shooting for a moderate weight and budget using a combination of new, used, and NOS parts. So far I've got a 2018 Fox Factory 34 coming (I'll have to adjust the travel to 120 mm), as well as the same ebay Fox DPS 165 x 42.5 shock that lots of others are using. I also just ordered BTLOS M-i29A rims. Over the next several weeks I'll search out hubs, drivetrain and brakes. Thinking of going Shimano XT 11 speed for discount prices.

Hi all,
Here's an overdue update, which is pretty uneventful. I've been riding my CS-041 on and off in rotation with my Devinci Atlas. I'm up to about 300 miles and have nothing to report. I've ridden rocky, rooty singletrack, gravel and asphalt, and it's done fine. I still appreciate the light weight, stiffness, handling, etc.
