Tuned Ritchey Pro ISIS crankset. 175mm length. Steel inner ring replaced with aluminium ring (extremely little use). New outer ring. Outer/middle mounting hardware replaced with aluminium. Splines and pedal threads in good nick. Middle ring has seen better days but it is serviceable. Original, worn outer ring included. Very nice light ISIS crankset. Inner ring bolts original steel, so might even manage to get it under 600g if you tried. £25 posted, payment by bank transfer.
