having a nice early ride at gisburn and clearing everything cleanly until… flying down the rocky steppy section after the big banks at hully gully and the rear mech locked up fully into the rear spokes. fortunately, the section was straight and the big slid to a stop without dropping me down the gully into the stream.
the rear mech totalled and the mech hanger bent into the block so it couldnt be turned, chain twisted 90deg to the verticle. 2 spokes snapped.
a couple of guys came steaming through to my rescue with a donated power link that got my patriot back to base as a very shonky singlespeed. big thanks guys.
advice, dont leave your mech in the highest position on your rear block when battering down rocks at speed.
