V brakes

[baron von greenback]

How can you tell if your bike has v brake mounts I thought v brakes and cantilever fit on any frame or am I wrong g

 

[Bike Hoarder]

Mounts are the same regardless of brake type, only U brakes are different.

 

[d8mok]

Cable guide is the deciding factor on most frames.

 

[Bike Hoarder]

Thought that after I replied.

I thought so that why I asked when the guy said it I wasn't to sure being new to this

Early cantis were closer to the rim, and the rims themselves were narrower, meaning the bosses were closer together.

With the growth of the mtb, by the late 80s canti bosses were standard, and v- brakes were designed to fit on them.

Cheers while on the subject i heard people say these brake levers are v brake or canti i thought you could use on both so is there any to tell the diffrence cheers

 

[bikeworkshop]

V- levers pull more cable.
12-15mm id say.
Canti levers pull more like 7or8mm

You can tell them apart at a glance by the distance between lever pivot and cable mount.

 

[baron von greenback]

The lever pivot is what holds the lever on which is the cable mount is that the round hole that holds the end of cable and i assume the gap is bigger on v brakes you have dumb it down haha dont suppose you have side by side comparision mate

Bit of a long winded comparison, the images show it all:
With brake levers used for cantilever brakes, the distance between the lever pivot and the brake cable end determines the amount of cable that is pulled. From the older style flat-bar lever pivots to the brake end fitting are typically 21mm. This in effect creates a circle with a circumference of about 132mm. If the lever is pulled so it moves from fully open to about 20-degrees, it will pull about 7mm of cable through the housing, and this in turn pulls the arms and brake pads to the rim.

The modern linear pull levers have a pivot to brake-end radius of about 42mm, and a large circumference compared to the cantilever compatible lever. The linear pull levers when pulled 20-degrees will draw about 15mm of cable through the housing. The long arms on the linear pull brakes at the rim are designed to work with this great amount of cable pull from the linear pull lever.

Modern drop-bar shift/brake levers have a relatively smaller radius compared to flat bar levers. Pulling the lever about 20-degrees will pull only 6mm of cable through the housing. The dual-pivot brakes used for these levers are designed to work with this relatively small amount of cable travel.
