Will a 650c wheel work on a mtb?(7 posts)

Will a 650c wheel work on a mtb?timfire

This winter I'm building up a mtb frame for my finance. It's only going to be used for the street, not the trails.

Anyway, I was thinking about wheels and was wondering if a 650c wheel would work in a mtb frame, because I know that a 650c is slightly bigger than a 26in' (571mm to 559mm, correct?). Now, I'm not worried that the wheel won't fit, but I'm worried that the braking surface on the 650c rim would be too big to fit in the brakes. (Similiar to a 700c wheel being too small for a 27in frame.)

Anyway, I was just thinking about whether it would work or not, and whether anyone has tried this. FYI, I will probably still go with a 26in wheel, because I already have 1 wheel.

PS: It's a TI frame (sorry, I don't know the brand), with a Trek CroMoly straight mtb fork. I'll probably build it as a SS with some mustache bars/ road brake levers, and a maybe Richey threadless stem and seatpost.

Isn't rear spacing different for road?spookyload

other than that it should work if the brake pads reach the braking surface.
Yes, but I would only need a wider axle or a mtb hub. (n/m)timfire

Depends on your brakes mostlyoff roadie

The 650 will fit almost any frame, to be sure, with the right axle. The problem, as you note, is the brake track.

Disc bakes- no problem, for obvious reasons. Heck, you can usually do 700c without frame clearance issues.

With typical linear pull brakes, you may or may not have enough vertical adjustment to reach the higher brakew track. It only requires setting the pad a few MM higher than normal (half the increase in diamter). If you do go that route, I'd look for a cheap linear pull ("V") brake with a lot of vertical adjustment and try it, then if you wanted something better you'd know how much reach you need.
