• So probably best to stock up on BH90 cables to ensure compatibility across the 105/Tiagra levers.

    I just saw UberBike have their own brand stuff, spec looks similar to BH90 with the 2.1mm internal diameter and it comes in a choice of colours, so orange and/or blue naturally pulls at the heart strings.

    Also, just realised, now I've got a new fork, I'll need to undo the brake line as it's all internally routed. Two questions, is it best to disconnect at the lever or the caliper? And do all I need to do is use a new olive, no need to trim down and use a new insert?

  • It depends on the caliper, lever and routing, but as long as there is no bango on your caliper, then I imagine disconnecting and unbolting the caliper would be easier as you then won't have to remove the bar tape etc.

    Unfortunately you can't just put a new olive on because it is crushed around the hose and barb. It may be possible to recover the barb but it is a lot of effort. Fortunately, you don't need a new olive. I've swapped loads of brakes without putting a new olive on, never had an issue with leaking.

  • I'm a little confused, you say you can't put a new olive on as it's crushed, and then say I don't need a new olive as you've swapped loads of brakes without putting a new olive in...
