Topic: Caliper Brakes for my Raleigh mv8*

Posted on: 19th Sep 2015 3:59 PM    Quote and Reply

Hey guys! 

I got a raleigh mv8 currently on flat bar and  setup, looking for an upgrade to dropbar and hence wanted to change my v brakes to caliper brakes. but the reach seems too much for most caliper brakes, will tektro R559 fit?

Any bros out there performed similar modification to their raleigh before?




Appreciate any help! Thanks all! =DDD

Your best options are cantilever brakes or mini V brakes or a travel agent from problem solvers that allows you to use standard V brakes with the shorter pull STIs. Roadie calipers won't fit on that frame with out a lot of messing about with adapters and the like+ they will limit your tire and rim choices.

BTW I have read people on line saying that the newer generation Shimano STI's ultegra 6700 or later work with standard V brakes as Shimano increased the cable pull, I have tried this with Avid Single Digit 7 V brakes on my CX bike and my experience is that they don't. The CX70 cantilevers I have are 10 x better than the v's with STIs

Pretty much any canti that fits on V brake bosses will do. I recommend the Shimano CX70 as they are adjustable to take any size of rim you want. They also take standard Dura Ace pads so you can get aftermarket pads such as koolstop which are much better than stock. The CX50s do neither.

Note that you will need to buy a front and rear cable stop if going for cantilever brakes Which can be tricky in SG; Sulaiman at the Rebound Centre can get them or may have in stock.
TR bikes used to have problem solvers stuff, you can try them for Travel Mates or you can get online. That would be cheapest as you can use your current V brakes

hi;

Iirc, yes the longest reach tektro brakes probably will work.

best for you to get an old pair and then do a test fit.

you can try upgrading the wheels

the stock wheels on the mv8 suck

and by the way, you need some special machining for the front deraileur to work properly (or as smooth as a road bike) if you really wish to go 20s. it's because of the different geometry of the mini velo.

Sulaiman of the Rebound Centre (only he) can machine out something for you.

good luck, have fun.

try going 56t on the front, that should give you a workout

edit* disclaimer

I am not personally aware that the front D needs a special adaptor, but a friend of mine who is waaaay more into MVs than me has done that with his front D on his MV8 - turning it into a MV20
