Idly looking out for a large road/CX/touring/whatever frameset which is singlespeedable.
Must be big: rough minimums are effective top tube of 60cm or reach of 40cm, but ideally bigger.
Caliper, canti or disc brakes. If rim brakes, will consider a rolling chassis or maybe even a full bike. If caliper, will consider frames without forks.
Track ends, horizontal dropouts, sliding dropouts or EBB.
Budget is probably low, but try me.
