Re: 87 Diamondback Arrival ''XT" Alu, c-stay U-Brake. Offers
Hi mate.
Size 16.5" c-c
I don't have a gauge but I think seatpost is 25mm.
Headtube 1 1/8
I'll post some pics
BB cup haven't really tried yet. Large spanner won't do it. I made one of those tools Sheldon recommends for gripping it front and back but I haven't tried it on this yet and I don't have a vice. I reckon they're just a question of having the right kit. If you don't I could take it down to Cranks and use the vice there.
