Cotic Roadrat and V-brake setup problems. Help please.
My gf has a Cotic Roadrat fitted with v-brakes. The fronts are fine and work great but the rears are a bugger to set up properly and get a nice feel. I personally feel that the Rear seat stays and canti studs are to far in. When the arms are fitted with the brakes touching the rims and the small brake pad spacers on the inside the arms sit out at quite an extreme angle, giving the brakes a very soggy feel. She is running LX brake arms on Mavic A319 rims. I have tried narrower rims and parralel push brakes but still encounter this problem. Has anyone come across this problem or does anyone have an idea about how to solve it without going to discs?Posted 9 years agoMountainMutantMember
I would agree but I am no V brake expert.
I had XTR V’s on mine and that was my first experience of that kind of brake. They really stuck out at the back.
I got rid as I was getting through pads at such a rate it was costing a fortune. Running disks now. Much better!

Tried all of the above and they still angle out quite far when pads are in contact with the rim. If they would sit more vertical like on my On-one then it would be fine. She is running deore levers by the way. It Seems to me that the canti studs are placed to far in.Posted 9 years agoMarburgMember
+1 this problem. As far as I can tell, the posts are way too close together. Compare the post-to-post distance in the front (or indeed, any other MTB) to the rear.
Between this and some disc tab alignment issues, I'm not exactly thrilled with my RR experience thusfar….Posted 8 years agorichccMember
Can relate to this problem to with my RR – brake arms don't quite stick out at 10 to 2 but they're worse than 5 to 11. Thought I'd got something in the wrong place when I changed pads. Got a BB7 on the front and will probably put disk on back at some point to though then think adjusting chain slack might become more of a PITAPosted 8 years ago
