What are these called?

I can't for the life of me find a search term that brings up this particular type of v-brake mount up on the net...



I began building up an old steel mtb/dirt jumping frame I had lying around to more comfortably pedal with our baby seat (& baby) on the back
Currently the baby seat is on the back of an old SS road frame - this is ok on paved, flat paths, but not much else!

When I realised that the 3 threaded holes on the frame needed this type of v-brake mount, I came grinding to a halt. I've spent a fair bit of time on Google & have figured out what I need (i.e. the mounts in the photos above), but I can't find them for sale anywhere! If they can still be found for purchase somewhere these days, I'd love to know where, or what term I should be searching with to find them!

something like this?

halo specific (discontinued): http://www.chainreactioncycles.com/Mode ... elID=42117" onclick="window.open(this.href);return false;" onclick="window.open(this.href);return false;

on-one specific: http://www.on-one.co.uk/i/q/FSOOCBS/on_ ... _m6_thread" onclick="window.open(this.href);return false;

they're called canti bosses or vee brake bosses. might want to contact on-one with your hole spacings and sizes to see if theirs will fit your frame.

Thanks for the reply mentok.

The first link you gave is where I got my first image from in the original post. The item is discontinued, so unfortunately not much good to me. I'm pretty sure this is the exact mount I am after, as the old frame I have was a 'Da Bomb' Cr-Mo frame (look at the other pics once you have the link open).

The On-One bolt on boss looks ok. I don't care what I use, as long as I can find something relatively cheaply that will do the trick. I reckon I've seen better looking options in google images, but I have no idea where to find them.


I should mention I am in Australia I guess, when looking at availability of parts.

As far as search terms go, "v-brake boss" is where I started, but this generally brings up the screw in posts/pivots if entered into eBay or other similar sites. I need to find the bolt on version as the posts/pivots on their own don't have the little holes for spring tension adjustment. Plus, I'm pretty sure the thread on the posts/pivots is larger diameter than the actual frame bolts - these seem to be similar to disc brake mount bolts (an ~5mm outside diameter bolt fits)? I was just wondering if there is some specific name that might all of a sudden bring up the bolt on bosses I'm chasing

Edit: the 1st pic looks huge on my computer - sorry!

Problem is they are frame specific, no standard, so you'll be lucky to find anything other than the specific one for your frame that will fit.

This may help
