This is my current commuter. It's a 50 mile round trip which I do three times a week.
2011 Surly Long Haul Trucker frame 60cm which I built up with some bits I had already and some bits I bought and then kept tweaking and buying more bits. It's the first bike I've built up from frame and fork only and I love it.
These are all the bits on it:
Mavic A719 rear wheel, XT hubs and DT Swiss spokes (I didn't build the wheels) from about 2007.
Rear brake is some early 2000s shimano V brake. Might be Alivio, can't remember.
9-Speed LX Crank and rear mech, Tiagra triple front mech - all from around 2007. SKS mudguards. Brooks B17 which I swapped in 2004 for the crappy saddle that came with an old Trek Hybrid, I definitely got the better deal there.
Ritchey seatpost that came with my roadbike.
Dura ace bar-end shifters
On-one midge bar. Love these flared drops.
Cane creek headset and drop v levers.
I must adjust that rack, it's on the piss.
I recently converted the front end to disc with a surly disc trucker fork I got off eBay and a BB7 brake. Which also meant a new front wheel. I think it's a Mavic XM319 rim on XT hub. With the original fork I cut the steerer tube very badly and too short so I left the steerer tube full length this time, hence the mountain of spacers.
Tyres are 35mm Schwalbe Mondial - these are great.
Zefal frame pump.
Bar tape is Fizik, I took it off my road bike when I was matching colours to frames like a sad roadie.
