Appealing for any information/experiences of anyone who might have had something like this happen. Over the past month 4 people I know who own a Commencal supreme have found cracks on their bike. 3 of these have been the 4.3 variants with one of them actually failing causing the bottom bracket assembly to snap completely off the bike. The last of the 4 bikes was a V4.4, this bike this bike cracked in the same place as the 2 other V4.3s. These bikes seem to all have failed around the bottom bracket, 3 of them having cracked in the exact same way. These 4 experiences, paired up with the fact that they have a history of doing this has left me questioning why there is such little documentation around.
Id be interested to hear if anyone else is having these issues. I'm particularly interested in the V4.3 and V4.4 variants of the supreme this should range from around 2017 to 2022. Cheers
I have a 2020 Supreme 27 and found a hairline crack near the bb.
Edit: pulled off the rear fender and found a small crack on the seat-stay as well.
I emailed Commencal and let them know, being transparent that I bought this bike second hand. They were still willing to extend a 10% discount on a new frame. But since their new frames are mullet only and my bike is 27.5 front and rear, the cost to switch frames and fork and wheel are cost prohibitive. And all that for a 2 year warranty.
The new Trek Session frame in the other hand will accept my current wheels and all other components, and has a lifetime warranty.
