Circumcision Circumcision Question: So Dave, how many R20 Aheadset conversions have you done? 204316192 Answer Ten R20 and two RSW - so far. The Twenty headset, like most other elements of the Twenty, was taken directly from the RSW parts bin at Raleigh, so RSWs also benefit from the Aheadset conversion fix. Do you like the pretty colours of all the little off-cuts? 204316193
