Selling my trusty P7, finally admitted to myself that it really is too small for me and have gone up to 19".
Not sure of the precise year 2006 or 2007. It's got the sliding dropouts so can run gears or single. I ran it with 140mm forks, but it's happy in many guises.
History is that I bought it in Nov 2011 from my local bike shop owner, he'd had it from new but used it very little - it still had the original tyres on it! It's had plenty of use in my ownership but had been well cared for, few cable rubs and rubs to one decal but everything is straight and as it should be.
I'll leave the Race Face X Type bottom bracket in there and the seat clamp. I'm after £135.
