Hello all
My BMX has a dual pivot rear brake (so dual pivot, but 'high' pivots (ie about an inch higher than canti/v brake mounts). It had a Giro (which I had no use for, its just a pub bike, I've no need for whips) which was broken, so I took it off.
Trouble is, the bike has routing for twin cables from the giro to the rear brake - they come in from both sides and pull directly on the brake, rather than having a single cable with a bridging cable - so basically i have no central brake boss, only non-central ones.
So (phew) onto my question. Can I run the brake without a Giro? Think there would be 3 options
- Get a brake that runs off the 'high' pivots that are self contained (like a traditional caliper or V brake), so I can just run a continuous outer.
- Split the brake cable from a single lever to two outers, which could then link to the brake).
- find a lever that pulls 2 cables (I think I've seen one in the past)
any ideas?
sounds like you have a U-brake type setup, but really odd having a double cable to the brake, normally the double cable is brought to a gyro widget and a single cable runs to the brake.
Can you use something like http://www.winstanleysbikes.co.uk/product/31550/Surly_Rear_Cable_Hanger? on the seat clamp?
Then run a single cable and straddle wire to the brake?
yeah its twin cables the whole way, then a U brake - but instead of a bridging cable on the U-Brake, the caliper arms are pulled directly
the bike is one of these

I'm not sure a seatpost mounted hanger would work, as the brake is underneath the seatstays? its also very tight under there, the arms of the brake actually touch the seatpost when fully closed so I think anything would have to come from the front of the bike?
is it possible to run a rear U brake like a v-brake - ie a cable directly pulling the caliper together, rather than linking on a bridging cable? I think it might be done on front brakes - found this image

Thanks for your help

Yeah you can, I've seen some U brakes run with V brake noodles up front as the cable through the centre bolt gets routed down the fork leg then back up to the brake.
can't hurt to try it..
