105 Brake Levers and Vbrakes

[derrick]

Can i use V Brakes with 105 Brake Levers, does anyone know?

 

[Poacher]

105 brake levers are very unlikely to pull sufficient cable to operate V brakes.

You need a widget to change the amount of cable pulled - read this.

Generally you can't mix calliper levers (such as the 105) with V brakes. The leverage will be all wrong, and you may well get the lever bottoming out before the brakes do any useful work.

Cheers Colin, that looks like the way forward

Or use mini-V brakes, which need less cable pull. Or cantis for that matter.

Yes it looks like it could be Cantis, been doing a bit of research and they are fitted to a few cross bikes, So that's the way to go.
Thanks all for the input.

From looking at the photo my mind cannot conceive how these work.

I thought it was a strange idea so I looked it up ... See this PDF file.

Basically, the cable is wrapped round a small pulley, emerges from a slot in the side of it, continues round a larger outer pulley and then goes to the brake. So if the inner pulley moves by 20 degrees then the outer pulley which is attached to it must also move by 20 degrees but the cable is being pulled a greater distance because of the larger diameter of the second pulley - a clever idea!

Cheers, i think i understand it now.

I have 105 shifters and Tektro Oryx cantis on my Claud Butler Dalesman touring bike, and the set up works very well.
