Thanks for the advice!
I think the chain ring and cranks are in usable condition, but thank you for the heads up. It's a rad looking chain ring, so it would be a shame to lose it!
It's probably not too clear from the pics, but the chrome had completely come off in some places and the rust was pretty bad. I like the original colours, but I'd like a bike that's going to last another 20 years even more!
Going to keep it geared, I have a charge plug for singlespeed tomfoolery, but it'd nice to do a little more long distance riding pon the weekend.
Stem wise, I think the current one is 110mm so I'm looking at getting a 80 or 90. Not sure on make yet. Probably whatever armourtex have knocking about.
And awesome! I suspected it might be a slightly mixed bag. Nice to have record on it! Fancy.
