Re: BXT-MTB-117 150mm AM bike
Those swing links look much more solid. My first impression of the 831 — before we even knew about the flex/play issue — was that its links looked like they’d have questionable longevity. My son built up this frame (BXT MTB-117). I can confirm that all the pivots are now thru axle. I have attached a picture of the top pivot. It's massively overbuilt. A few things to note: 1. The rear post mounts are default for 180mm rotors (not 160mm as shown on the specs.) 2. Internal routing was fiddly and in the the case of the rear hydraulic hose, a little tight at the head tube. Either the opening diameter was undersized, or there was a burr in there. We needed to open up the hole a little. 3. 24mm bushings for the shock pivots. Some places still show 22mm. 4. I do not know why some people seem to think this is some updated version of the Tideace AM831. The dropouts, bushing sizes, BB mounting standard, and general look are not the same as the latest generation of the AM831. The front triangle on the BXT is missing the dated "camel hump". This bump might have been cool in 2015, but not today... 5. My son is notoriously hard on his bikes and so far there are no issues with flex or failures (but he is under 140lbs so YMMV.)

Re: Spcycle 2023 New Travel 120mm Super Light 29er full suspension frame
I expect a lot of people would want something like this as a down-country/short travel trail bike because of the TT and reach numbers. Which means most would like to see the seat tube lengths shrink by about 30mm for every size in your geo chart for fitting longer dropper posts and lower standover. You might run out of room for a second bottle cage, but you can move it under the downtube.

Re: Spcycle 2023 New Travel 120mm Super Light 29er full suspension frame
So you want a short travel trail bike not a lightweight xc race bike? I honestly don't want either. The fact is this bike frame has 120mm of travel which already pushes it out of the "XC race" category. spcycle can cater to a far larger market if they had one frame that would satisfy both the XC and light trail duty requirements. All I am suggesting is shrinking the seat tube can make the design far more flexible and capable. May 03, 2023, 08:37:26 PM |

Yes, we have completed 3D printing and mold development. So the geometric parameters will not change. thank you Didn't you literally ask for suggestions on the mold in the original post?

He said: I think it would benefit spcycle greatly if they took a look at how the market is trending before committing to creating their tooling. It seems to me that this frame isn't what a lot of people want. There's always going to be somebody who will buy this, but if I saw this on a catalog page I'd take a pass on it.

Re: Zrace m1 x4 idraulic disk brakes
ok, I read that they work with mineral oil, what type of oil do you use? overheating problems? Thank you. I've bled them a few times with shimano mineral oil. I regularly do steep 2000ft fire road descents. They have never overheated and fade is detectable but minimal. These brakes are decent. October 31, 2023, 11:16:37 PM |
