I plan to fit it to a FS bike, Ibis Mojo SL and not being the lightest rider out there, should I be concerned about breakage? Post will be 1 cm from min insertion so a lot of leverage.
Great for road use; off-road probably best restricted to use by waif-like cross-country whippets.
Big, rough riders may want to steer clear. Bontrager lists this post on both its road and mountain bike component websites, although in the blurb it does say it’s for “road use only”, which may be worrying for some.
Bontrager doesn’t give a rider weight limit, though. Our 80kg road test pilot had no worries, with thicker post walls at the front and rear compared to the sides helping to keep ﬂex within normal limits.
Many Trek pro cross-country racers already use this post, so if you're hitting the dirt it’s up to you to decide whether you’re light/careful enough to live in harmony with this lightweight carbon masterpiece.
