From 27" to 700c, you should have no problem by adjusting the pads 4mm towards the wheel's hub. Just make sure that the pads align perfectly to the rim when the brakes are applied.

You will not have adequate spoke length to move to 700c from "26" or "27x1/4".  Your mechanic will have to buy a new set of spokes for the wheels, which can cost as much as a new wheel for the set.  The labor costs as much as a new set of wheels.

Also where do the 26s come in?  Was that a typo for 27?  (26" is a common size too, for mtn bikes, hybrids, etc.)

A bicycle with 26 in mtb wheels will not have room for 27 in or 700c wheels.

http://sheldonbrown.com/tire-sizing.html
27 inch wheels have an ISO (bead diameter) of 630 mm.
700c wheels have an ISO of 622 mm.

26 inch x 1.00-2.25 wheel have an ISO of 559 mm.

This is not necessarily true. I have an ugly 80's Schwinn Mirada Hybrid/MTB that came with 26" wheels. There is plenty of room for 700c wheels on that thing. The brakes will need some tweaking or replacing though.

Indeed.  I tacoed a rim once and was running a 700 rear wheel with 35C tire on a 2003-ish Trek 4300.  Couldn't run rear brakes and the handling was different (but not bad), and there was plenty of room for the wheel/tire.

Adrian, what frame do you have?  And what size tires will you be running?  Will it be a fixed-gear?  Most frames you can fit lots of different sizes of wheels on.  The limiting factor is usually the brakes.

Well, at least I am now getting some info that I need for my 1974 Schwinn Continental rebuild. I wanted hot pink rims, but can't find them in 27". So, I will be changing to 700c's so that I can get hot pink rims. I am also looking for a hot pink saddle, bar tape, and maybe even some pedals (platforms, not anything to clip into...maybe). I am trying to get her into a pink and black color scheme for the Apple Cider Century (outside of Chicago) and the Perimeter ride here in Chicago.

Thank you to all of you that have given the above info. Decisions made due to that info.

 

Respectfully,

 

Manny
