hoping some one will know the answer. my cable is frayed at the clamping point on the mech. I want to replace it. my bike is a Btwin ultra AF 720. it has internal routing, does the cable housing (outer cable) run through the frame or is it in two pieces?
thanks Gary.

it almost certainly does not have housing running all the way through the frame. Also it can not be two pieces - if I understand your question correctly. What you refer as a second piece is probably brake cable housing underneath the BB. What I do to replace internal FD cable is to release a cable from the FD, pull it somewhat by the front housing to expose a cable at the point where it comes out the frame at the front, cut it there and bend, so that it does not fall back into the frame. Pull out the front part of a cable from the shifter, replace the new cable into the shifter and through the housing. Then attache the end of it to the old cable (that you bent so that it stays put), and push-pull that joint back through the frame until it comes out at the guide underneath the BB. Then some fishing until it appears through that small hole in the frame, leading to the FD. this is simplified - it requires some fiddling, perhaps removing BB or releasing the RD cable and removing the plastic bracket underneath BB ... depends how lucky you are and whether there is a sleeve connecting the BB bearings. Or ... get some of that plastic guide housing, thread it over the old cable until it appears at the front frame hole, guide the new cable back. Oh yeah, get some mind relaxant ahead ... it usually is required for that job

You need to release the rear cable as well, just some slack to allow removal of the plastic guide under the bb which they share.

Thanks or the replies, other than the frayed end at the FD the cable is good, but a little OCD about these things, and the fraying will be a weak spot. a little relaxation before carrying out I believe.

my OCD hears your OCD, but for just fried end it isn't worth it. clamping point - at the tightening screw is different, as a cable could snap. for the cable end, just rewind, cut shorter and squeeze a new cap ... well clamp as mentioned above, you might need to temporarily release RD cable, which is always a risk for frying. so, best not to do it unnecessarily .

Thanks, I also have the problem though which freaks me out, that the brakes are set up continental style front on left rear on right. in theory it is simple brain tells hand squeeze the opposite lever but that takes time, in my book that's a dangerous situation. years of using the brakes in UK style is hard to break forgive the pun. so may recable the lot and change the bar tape to some suitable garish colour. sure your OCD reads my OCD.

Chas might want to chime in here, but I believe that brake situation is a failure in bike preparation for sale in UK. I'd take it in to Deca shop and ask them to rectify. Fortunately, they are very good in standing up to their product and services.
I feel the same regarding the brake set up - once you develop good technique, it is difficult to think 'opposite', especially because the whole point of a practice is to develop a muscle memory and dismiss the whole process of 'thinking' in an emergency situation.
Interestingly enough, I'm joust about to post my impressions on other Deca bike, and had also notice the opposite brake set up in store. However, this is about hydro disc brakes, so makes even less sense to re-do it in shop.

Certainly if you bought the bike new the brakes are legally required to be swapped, if not then a previous owner may have wanted them that way round. We do have to swap hydraulic brakes too.

Sorry, completely skipped my mind that bike could have been purchased second hand. But seriously, are all hydro bikes coming to UK with non UK brake set up, so that they have to be re-tubed, re-wrapped and re-bled??? If I was Peter, that would be my goal to resolve and earn a fat bonus Looks then Paulinblack like I was able to test for a 5 minutes the only available GF in whole London . It's on the floor with the original brake set up.

Yes they're internet only, my colleague has one of the first which needed the hoses swapping in store, he was replacing the bar tape anyway. It looks really good 'in the flesh' and he's pleased with it.

The 720AF is 1400€ and £1050 so not sure how they work out exchange rates.

We are trying not to increase prices but I think it's inevitable really, some have gone up already.
