Yet another P2 thread!

[yostumpy]

I'm after a rigid fork for my orange P7 ( mid 90's) At the mo its got old rock shocks , with a short travel, that are well buggered. So am looking for a pair of P2 cantilever type forks, 1 1/8" NON threaded steerer of 220 /230mm. Not fussed on whether they are db or tb, as also not that worried about being minters, as its a winter bike. Now the fork length thing I'm a bit unsure of . Are there 3 lengths, 400 , 420, 440mm if so I think I need the 420 ones. Ta muchley.
