It's fine, the derailleur is doing enough tensioning to keep it on but the BB is longer than i'd like so it's a bit noisy which doesn't help that.
The cup of the appropriate sized BB i've got is threaded and I'm trying to find a new one so with the right chainline I think it will be perfect; I'd just be careful with making sure the chain is the right size as even an extra link can make the difference.
Just finished building up a new beater as my bright yellow nago Cx bike is very fun but very conspicuous....
Sirius lopro frame in 753 OS tubing as spare parts stuff for the rest: single ring chorus crank, xenon rear mech, 7spd shimano single shifter, old suntour wheels on mavic M3cd rims, 7400 dura ace calipers etcetc.
Pretty nippy, will wait and see what it's like hunched over with heavy backpack on ...
