Sometimes the internet is no effing use at all. I think there was a significant geometry change to the Pista in 2012. Everyone talks about the frame (based, I reckon, on the 2007-2011 geo) having a steep 75 degree head angle, but the current charts show 73 degrees; similarly every post talks about a 28mm offset fork (which gives 62mm of trail with a 23mm tyre, as fitted back in the day). But 28mm on 73 degrees with a *25*mm tyre (as fitted now) would give 75mm of trail, which would be mad. So I think the new fork to go with the new geo must have 40mm of offset, but can't find anything to confirm this anywhere. I ask because I fancy changing the fork to something carboniferous (for no reason) but don't want to bugger the handling.
Anybody have any idea? Or do I have to get out bits of string and start measuring?
