Polo Bikes

i've never noticed issues with the axle kev.

cable discs pull the same amount of cable as a v-brake, (unless they are a new-fangled road/cyclo-x disc caliper). So no, you don't need a travel agent.

My axle just got moved a bit in the dropouts, I'd say I just need to sit down with it for ten minutes and sort it out, when I am not in a rush to leave the house.
It was annoying trying to tighten up the bolts so the axle stayed perfectly straight.

Not sure about the model of the caliper I have. Will look it up later. But it didnt look much different to the type of one that you have on your forks.
