Well, looks like I got this finished just in time for my self-imposed February dead-line*
Some spec changes were forced upon me: The Salsa stem was too long, and the front cable routing was ungainly, so I pulled out this neat Specialized one, but this is still 20mm too long, so I will replace with something more suitable, in the right dimensions once it is sourced; I lost the front mech cable pulley I had carefully put to one side, so I sort of made one out of washers, it's serviceable, but not ideal; the fork needs cutting down 5mm, the Mavic headset, though deep as f**k is still a little too long; I haven't had the heart to cut down the NOS Suntour Accushift cable outers whilst I don't have the right stem on there, so they look a little daft; I need a 25 tooth granny ring, the current 26 tooth is a little too close for comfort; I think the red ano skewers might be a bit bling for me, but they are British, and were introduced in 92, and sort of work.
Enough prattle, pics:
Suntour XC Pro 7 speed non-MD; Mavic M231 rims; Specialized stem; True Temper bar; NOS Ritchey Mega/Alpha bite tyres; Mavic 315 headset; Zero skewers; XC Pro post; Dia Compe 987/XC Pro brakes; ODI 1/2 attack grips; Selle Turbo saddle; XC Pro pedals with Cateye clips and Lapize vegan straps.
*it is the 29th today, right?
