Mudguards AND brakes that work
November 30, 2013Posted by on
After the recent near death experiences with cantilever brakes on the Uncle John, I had a re-think and decided to somehow make the mini-v’s work with the mudguards. Given the amount of people who arrive at this blog through searching for info on this humble English cyclocross bike, I thought I’d better share my solution.
When I first fitted my SKS Chromoplastic P45 mudguards, it looked like the Tektro 926 mini-v’s wouldn’t clear the top of them (which led to the unsuccessful experiment with the cantilever brakes…) On closer inspection, they can just about clear the top of the guards, especially if you file down the underside of the bit where the noodle goes through. I was always happy with the power of these brakes, but was annoyed at the lack of pad clearance, which was only just feasible with straight road wheels but a rim wearing nightmare off road. With their reinstallation, I decided to try the ‘Travel Agents’ by Problem Solvers to gain more clearance. These little gadgets are as clever as their name, essentially converting the short amount of cable pulled by the lever into an increased amount of travel at the calliper. It does this via a wheel, which replaces the noodle. It may look a little unsightly, and weight weenies will moan about the extra grams, but it works well and has less friction than a noodle.
The Travel Agent seems to do it’s job well and though it didn’t change the pull ratio as much as I thought it would, it was enough to allow a little pad clearance and still have effective braking without the levers hitting the bars. I’ve just test ridden them and the brakes felt as strong as the SRAM Force callipers I’ve got on the Boardman. So I’ve finally achieved my original objective of having mudguards big enough to accommodate my Schwalbe 30mm CX-Pro’s and still get decent braking with my SRAM Rival levers.
To be honest, I should maybe have just gone with disc brakes when I built the bike, but it’s a bit late late now as I’d have to buy a new fork and build new wheels, as well as the new callipers. Maybe on my next ‘cross bike…
