ok. I've bought my pr in February and changed a lot since then. First of all I guess you should replace BB and cranks. No trust to square tapper. If you still running a standard shimno frewheel - throw that sh*t away. Replace to ACS i guess. I ran tensile though. Then, after 5 months of nube riding, rear Hub axle snapped. So, replace rear hub as soon as you can. Everything else - pretty good, unless you find it really heavy(f.e. front hub, front rim, rear rim). All in all, I changed my wheels and system. Very happy with that. great bike.(though i snapped my frame and be getting smth new now) 924 ???? I bought mine for 707 last year
