This is a 2007 S-Works Tricross frame with its standard forks, seatpost, seatclamp, headset.
Specialized brought 3 Tricross models into the UK that year; two complete bikes and this top end frame (E5 aluminium with a carbon fork).
It wasn't until a couple of years later that they split the range to be CruX (the CX "race" variant) and the Tricross (which became a sort of drop-bar hybrid). This isn't what you'd call a pure CX race bike but it'll do that and most other stuff besides, it's an extremely capable all-rounder.
The frame is a 61cm semi-compact with a 59.5cm effective top tube. See pic below:
It takes canti (or mini-V) only, it's not disc-ready. Easily takes 38mm tyres, would make a great commuter or even a winter road bike. I've used it for all those things as well as off-road rides. Generally VGC, a couple of small cable scuff marks. Chainstay is unmarked - it comes with the Specialized neoprene chainstay protector which fits around the cable stop.
1 1/8" headset (included along with about 30mm of spacers - there's loads of scope for cutting the steerer down), stem (inc) is a 120mm 6 degree Easton EA70 for oversize (31.8mm) bars, seatpost (inc) is a 27.2 carbon (VGC). BB shell is 68mm, takes all the usual internal BBs. Frame takes a 31.8mm band-on front mech. Rear dropout spacing is 130mm (so basically road wheels - I used a 130mm Hope road hub in there built onto an Open Pro).
£180 inc P&P via whatever insured courier you prefer or I find! Or you can collect from Manchester area or I'll deliver within a 20ish mile radius.
