If anyone is getting a creaking & cracking noise whilst pedalling under load try your rear axle; my Jekyll starts to get noisy after about 3 rides – you can’t really see or feel that it’s loose but undoing the QR lever and nipping the axle up a teenth of a turn always fixes this for me. It’s almost like it could do with knurling on the hub ends instead of just smooth alloy.
Also, did anyone get anything more than tubeless valves in the box, such as rim strips etc? Or are the rim strips fitted to wtb i23 supposed to be tubeless ready?
