Re: Stumpjumper clone
Hi all, I wanted to share my story on the Airwolf Stumpjumper clone. https://airwolfcarbonbike.com/product/yfm018-2022-am-carbon-mtb-frame-29-full-suspension-frames-stumpjumper-boost-148mm-enduro-rear-travel142mm-racing-mountain-bike-frameset/ I ordered my frame back in via Airwolf in May. I ordered the Specialized OEM parts: chainstay guard, shock top bolt, flip chip and the down tube protector. When receiving the frame The down tube protector was wasted as the holes for mounting is was not drilled and the top bolt needed 4-5 mm removed to fit. Rest fitted in - flip chip needed some brute force to fit (I did not resort to removing material from chip or shock fork). Second check was to check bearings and bolts. As already elaborated by others the tolerancesn bolts is in the bin. Bearings is fitted on axles with locktite as there is almost 0,2mm play on all bolts. Bearings is just poor quality - all bolts and bearings was binned and OEM bolt and bearing set was bought. Further more the the seatclamp was replaced with a bolt-type as the one delivered with the frame is crap. I put two rides on the bike - 1 XC ride and one where the frame was stressed a little - a couple of 1 m step downs at speed and railing some berms at high speeds and 5-6 small jumps 2-3 meters with ok landings. The result was that after 3,5 hrs of riding the front Cracked. The crack started at the main pivot on the drive side extending 30mm upwards. I reach out to Airwolf and I was promised a replacement, but I have zero confidence I the frame, so I will probably get rid of it once the replacement part arrive. Post thoughts: The rear axel, derailleur hanger and headset should also have be replaced as the stuff is junk/ questionable quality. If you are looking for a Chinese carbon frame I would recommend that you buy a frame from a company with in-house design-capability with actual knowledge about engineering and matrix design. These “look alike” frames is not worth the materials they are made from and will not stand to be used as the original design intended. If you are looking for a curb-cruiser they will probably be just fine. I am planning to cut the cracked fron and have a look at how the junker was built. If you have questions feel free to PM me.

Re: Chinese Carbon 29er Pic Thread.
There has been some bikes built. Me, my wife and my son has been upgraded quite a few times. Some great bikes StefanB. I have not built as many bikes as you, but I'm always thinking about the next one! I find researching and building these Chinese frames much more interesting than just buying a mainstream brand. It looks like you have some beautiful trails and scenery too! Where do you live? December 05, 2023, 01:16:37 PM |

Re: Carbonda FM 1003 / Flybike FM 1266 180mm "Super Enduro"
I had no problems with noise at bike parks except sometimes for harsh chain slap on braking bumps, which I assume will be fixed now that I’m installing a VHS Tape chainstay protector like the one on my FM1002.

New High Pivot Full Suspension Carbon Frame!!!
Hi Guys, Anybody here are interested in high pivot full suspension frame? Yes or no What is your preference on travel option F/R? My personal preference is 150F/140R High Single Pivot or 4 bars Horst link suspension? I think 4 bar Horst link is more straight forward Let's put our opinions here, so manufacturers know what specification they should design for high pivot frame in near future.

During the pandemic it was easy to sell a used bike so I could build a bike, ride it for a couple of months and sell it for component costs. Now things have changed, its very hard to sell a home built bike so I have to many bikes and therefore no space for more builds
