Replacing 26" Wheels with 700C ??

I have a Dahon Cadenza hybrid style bike which has 26"x1.25" wheels and V-brakes that are mounted onto brackets on the frame and forks. The spokes in the rear wheel have started to brake at a regular rate on the cassette side and after replacing 3 in about 3 months I'm starting to weigh up my options for change.
I could get the wheel rebuilt but I'm not sure how much that would cost so am unsure if it'd be worthwhile. Does anyone have any idea of the cost of rebuilding a wheel? And does anyone know where in the Northampton area I could get it done?
What I would like to do if i could would to replace the 26" wheels with some 700C wheels. There is plenty of room in the forks and frame to fit in larger wheels but I am not sure about the brakes. The current V brakes fit well but it looks like I'd need new ones with a larger reach (if that is the term) between the bracket on the frame and the wheel the pad would need to be aligned to. Do such brakes exist?

Like a streak of lightnin' flashin' cross the sky,
Like the swiftest arrow whizzin' from a bow,
Like a mighty cannonball he seems to fly.
You'll hear about him ever'where you go.

700s are larger diameter (obviously) than 26 inch wheels so you would have to replace the brakes. Some cyclo-cross bikes use V-brakes, I think, with 700s, but that's no proof that you could get brakes that would fit your bike as the mounting points may just be in different places.
Is there a need to change? You can get 'road' rims in 26 inch size (some small women's road bikes use them) and road tyres to fit, too, so you could get 26 inch road wheels.0 -
Can you borrow a pair from your lbs to see if they'll fit?0

I thought about doing this to one of my MTBs that is slowly becoming my run-around hybrid.
It could work if the bike has an option for disc brakes, but then you'd need to get a road or cyclocross wheelset with disc brakes. I believe they still use a 130mm axle length in the rear though... most MTBs with 26" wheels use a 135mm axle.
Yes, you can get 26" style road rims. They are designate "650C", but I am pretty sure they the tyres are not interchangeable. I.e. You'd need to get a wheelset built up with those particular rims.
Personally I'd just buy a new 26" wheelset like a cheap Mavic crossride or something...0 -
build cost is usually around £15 plus spokes cost
700c can work but your issue is brakes. You can either try an fit some deep drop dual pivots or use a bracket to allow you to fit the current Vs higher up.
The other issue is rear axle width - most 26" wheels are 135mm whereas most 700c road wheels are 130mm. You can either fit a longer axle and re-spacer it or have your frame 'adjusted' to the narrower setting.Facts are meaningless, you can use facts to prove anything that's remotely true! - Homer0 -

Are the Mavic Crossride rims reasonably narrow? I've looked on a few online sites and can't find much information (that I understand) about rim width, I currently use 1.25" tyres as I use the bike on the road and don't want to go to anything wider.

650c isn't 26". tyres etc are not the same.However I do run very narrow 26" rims and tyres in a bike made for 650c.This is a road bike frame and the caliper brakes just work. Many 650c tyres are rather narrow, mine are 19mm! as they are really for racing and triathlon use. Unlikely to get 700c wheels to fit a mtb frame as the brake mounts will be wrong. Disc is an option of course. Buy the hubs to suit your frame than join to rims of your choice.0

You wouldn't be able to fit a 700c rim and a rim brake - your brake bosses are at the wrong height. Likewise, a 650c wheel is different to a 26". Your cheapest option would be to keep your 26" wheels and fit some good 26" x 1.25" slicks - they will roll just as fast as a 700c road tyre.Make mine an Italian, with Campagnolo on the side..0
