Brake and gear cable advice please

leech

I've got a set of SRAM Rival levers connected to Rival front and rear gears and tektro brakes (all from my now dead Boardman Team Carbon) When I took the broken bike apart I foolishly cut all of the cables. I now need new cables for my winter bike creation.

Not sure what I need though. I looked on the usual websites and they only seem to sell Shimano parts. I notice that the old Boardman casings are Shimano, but I'm told that the inner wires are a different size?

1. Is this true?
2. Can anybody point me to the correct parts?

Any help appreciated.

for rival gear cables, sram says...

High quality 1.1 mm shifting cable and 4 or 5 mm compressionless housing, high quality, with non-sealed end caps of maximum diameter 5.8 mm and maximum length 16 mm

and for brake cables...

1.6 mm high quality brake cable with road-style cable end and brake cable housing with end caps.

this is from the sram technical manual, you can download from their website, it shows full instructions for fitting and adjusting

if you haven't done it before, note that the outer for brake cables is not the same as the outer for gear cables, getting it wrong may result in failure (you don't want that with brakes!)

if you go to wiggle, you'll see there are separate sections for brake and gear cables, the higher end stuff like gore ride-on, etc., but k.ble stuff is perfectly good

buying complete kits of bits is probably going to be simpler than deciding which separates you need, that way you know it will all match

when you cut the outer, and cables too for that matter., you need to avoid crushing the ends, there are special cutters, but you can do it with any good wire cutters, a file can be used to tidy outer ends

park tools site has plenty of other how to guides, so it's a good source of generic info to understand how to go about things

when you refit, keep the new pieces of outer the same lengths as the old ones

All good advice. You will need to review the outer lengths as this is a new frame. I had a quick look klast night at the same issue and the outers need to suit the new bike.

Thread hijack.

What's the best way to replace cables that run through the frame? I've never had to do it and don't want to start only to find that it's needs a fancy tool or whatever. I'd imagine it's v simple, but the actuality is harder to discover - Google doesn't throw much up unless I'm using the wrong search terms.

This is on a BMC Racemaster, gear & rear brake cables all disappear into the frame near the head set.

Apologies up front if it's just a case of poking the cable around till it pops out the other end.

I had to do this on my mountain bike. I attached the end of the new cable to the end of the old cable with a piece of duct tape and pulled the cable through. Worked a treat for me.

The simplicity of this is genius.
