Abstract
An apparatus is provided for removing a pedal crank arm from a bicycle axle end, wherein the axle end is received in a bore in the crank arm. The apparatus includes a tubular insert receivable in the bore of the crank arm and adapted to be fixed to the crank arm and a pressure screw receivable coaxially through the insert in threaded engagement therewith. The screw includes a bearing plug and a threaded member rotatably coupled to the bearing plug. The threaded member has a plug end and a drive end and a threaded outer surface portion in threaded engagement with the insert. The bearing plug has a bearing end frictionally engageable with the axle end to inhibit relative movement therebetween. The threaded member further includes coupling means on the drive end for removable coupling to an associate drive lever.
