Indeed I will, and sorry I didn't reply to your PM - I'm disorganised! I couldn't pop round today as Mrs Optix had the car. I'm free the rest of the week though...?
Insofar as I'd thought about it, I think the Cosmoses are 8 speed, yes...? And I have a max-7-speed shifter and mech combo for this bike...
no problem, just stick a little single speed spacer betwixt cassette & hub - I've done this many times... I have these spacers in abundance! I have another gorgeous wheelset for sale now too - 105 hubs on black Vuelta deep rims
how does thursday grab you?
