700c fork on 27 inch frame
Postby Dale E Grind » Fri Jul 11, 2008 1:13 pm
I'm just trying to recycle some old bits and pieces that's why ask. I have a few old 27 inch steel frames of no particular value hanging around and 700c wheels are easy to come by.
The only reason I want to do it is to build up a pub bike. SS/Fixie.... whatever.... just as long as nobody wants to steal it. It's all about being sustainable - Sustainable, Lowcost, Urban Transport (S.L.U.T.)
Anybody care to tell me why it cant be done?

Yeah - that's what I thought. And the front brakes is one reason to go 700c with the old steel frames. I've got a 105 claiper hanging around somewhere which should do nicely.rustychisel wrote:no reason at all... inch fork steerer in old frame, sweet as apples. No real issues with differing headsets (hiddenset, A-head, integrated etc), and the ability to use front brake caliper which needn't be unfeasibly long. If you're really unlucky the bike might appear to slope forward very slightly, but my guess is you wouldn't even notice it.

That's a wide variation in measurements though.

OTOH, would finding 27" rims and lacing in new hubs let me use modern short reach brakes on me old girl?

Then the challenge is availability of decent 27" tyres. They are increasingly hard and expensive to find.Mulger bill wrote:Tell us more about these drop bolts please VIC Mech. Photos too if I'm not asking too much.

The drop bolts I designed to use on my Campag calipers are fairly simple blocks of stainless steel with studs pressed into them. Flimsy they aint!! I deliberately designed them to be actual replacements for the original "in line" bolts with slots for the springs and everything. Polished they look great and will allow me the wider tyre choice that 700c wheels have rather than 27" these days.
having said that quality 27" tyres are still available from Continental but for how long is anyones guess! The drop bolts shown on Sheldonssite are pretty similar to mine only mineare shinier lol! I gave myself an 8mm drop between centres. If you can get some stock stainless bar and are any good with a file and a drill you dont need any special techniques but the holes and studs have to be an interference fit. The easiest way is to freeze the studs and press them into the block. you can go as technical as you want with reamers etc but thats not entirely necessary. believe me the studs in mine arent coming out again in a hurry.
Have fun.
