Cotic X - finished building it up 2 years ago yesterday as it happens. Has had skinny knobblies chucked on and ridden a couple of CX races, as well as taken me up and over the Pentlands and generally stood up to everything I can throw at it. Slicks on and it eats the miles - will be using it on the Bealach Mor.
Planet X Kaffenback, in its third incarnation. Built 5 years ago to do my first attempt at the Bealach Mor, with drops, 10spd and triple Campag and no guards. When my fixed wheel frame died it took over commuting, and threw my mousetache bars on. When the rims on the original wheels got worn so thin daylight could be seen through I got new ones built up with a dynamo on the front. Porteur rack for camerabag, took off the front mech and the extra chainrings (after this pic, as well as getting a matching rear 'guard).
Cotic Soul - frame no.73. Recently got rid of the heavy suspension form, and whacked on a lovely rigid carbon job. 26" slicks for urban japes, studded winter tyres for occasional commuter duties, Panaracer Fire XC for going properly off-road. Still. Love. This. Bike.
Sunbeam restoration - apparently from the 30s. Just acquired a second frame to try and harvest the BB from it (long story). Hoping to have this back on the road in the next week or two.
