I’ve had a set of XMM100 29er forks for about a year. They were OEM on my Canyon. Out of the box the two collets which the 15mm axel thread into had debonded and the forks required sending to Pace as a warrenty return. Quite a few other DT Swiss owners had the same issue on here but it seem limited to a run of 29er forks with a dodgy batch of adhesive. The warrenty return was smooth through Pace and took about 3weeks over all.
The forks them selves have been good, they arent as plush as Rockshox or Fox though, but definatly feel stiffer. They also take significantly longer to bed in than other forks i’ve had – Rock shox, Fox, Magura and cannondale forks all are super plush out of the box in comparison. They took abot 100miles or so to get the best out of them. My favorite thing about them is the lock out, the only fork that is better (imo) is the old cannondale headshox (cant cmment on the lefty as i’ve not tried it). As far as traditional telescopic forks go the lock out is great.
Personaly, i dont know if i’d buy another DT Swiss fork, when decision time comes it’ll be a hard decision – I prefer the actin of Rock Shox, but the stiffness and lock out of DT Swiss.
