Top bike Steve. Great pics aswell. Good to see some gripshift on these pages too.
Totally with you on the evolution thing aswell. I think that the main attraction to me of 'retro-biking' is that I can change my bike whenever I want relatively cheaply. Over the past 12 months, my Zaskar has had full M900, a mix of Suntour and Dura Ace, XT cranks, Middleburns, RC30s, RC36s, Thumbies, Rapidfire, Gripshift, all sorts of stuff. Because it's cheap now and I can sell stuff for pretty much what I paid for it, I can experiment with lots of different gear on the bike that I just couldn't afford to do when I was younger.
When I find a part that I really like using, it stays on the bike but the rest continues to evolve. I think that it is nearly there now, just a couple of parts to fine tune. Not sure what I'm going to do when its finished though... Start something else
