 Jensonusa.com carry a fair selection of tires and even have a budget

There are many more tires available in 622 than 630, and there are no

many.

Actually Schwable, Panaracer and Continetial to name a few still make good 
quality 27inch tires.  I agree that you do have more options with 700c but 
that doesn't mean there are no good options for 27inch.  

Hugh check my posting here is you want to see what your options are today

With cantilevers, some frames and some brakes have room to move the pads

Re: [RBW] Re: Question 27 wheel conversion to 700c wheels and maybe to 650b

2013-03-26 Thread Minh
i will echo what steve says, measure!  i made the same assumption a few 
years ago (still have the bike), and did the conversion because the 
existing wheels were chromed steel (in poor condition), the back was no 
issue even with short reach side-pulls.  but the front fork had tons of 
tire clearance already, so switching out to even long reach side-pulls 
didn't work, i used a make-shift drop-bolt for a few years until i found a 
crazy long reach sidepull (~75mm ish) made by shimano which i'm using now.

This was not an uncommon occurence as i think campy or dia-compe made 
machined drop bolts a long time ago.

I don't know Contis at all.  The Marathons are a heavy duty touring
tire.  Where do they sit in Schwalbe's hierarchy?  Scanning their site
quickly it looks as though it's roughly comparable to the Pasela in
Panaracer's hierarchy, and not one of their high end tires.
