Any question answered...

I'm after some new 27" wheels to revive a 1960s/70s ish frame. I'll be getting the stays spread to take a 130mm hub so I can run 9 speed, which I assume means I'll have to buy some new road hubs and some new (or NOS) 27" rims and have them built up.

What are the options for new 27" rims and tyres like? I've had a go on google and looked at some of the usual suspects (eg SJS Cycles) but there doesn't seem to be much on the go. I'd just like something good, but frankly the 27" equivalent of a Mavic Open Sport (or similar) would probably do the job.

Does such a beast exist? Any advice appreciated - and apologies if this has been covered already.

Anyone got an opinion on Velocity Twin Hollow rims versus Rigida AS27 rims? The velocities are £40 each, the rigidas £25. I suspect the velocities are better, but are they £15/rim better? I don't really know much about this. Has anyone here built wheels with either?
