Routing rear brake cable outer housing around seat post

[Shut Up Legs]

Yes, the thought of installing v-brakes had crossed my mind. Whatever brakes I use, they would have to leave enough room for the mudguards to clip on, though. I guess for now, I'll just have to route the rear brake outer the standard way, and try to minimise the cable bend as much as I can.

The cable must be routed via the hanger at the seat post. Just make sure there isn't too much bend.

I know. The problem is ensuring there's not too much bend. Because the cable needs to bend upwards from the top tube, and then down to go into the seat post cable guide, there's always going to be some bends. I wish there was a way to do it that didn't bend the cable so much.

If you have the old outer, just chop 5mm off on the new on and see how it looks. If still too bent, chop a little more off. It's easy to chop too much off.

Yes, I still have some outer cable to use, so I plan to do just that. Judging from the picture I posted at the start of this thread, I can reduce the cable bend a bit more .

OMIGAWD!

The problem was simply that the cable outer was too long. Refit the original piece (or a new bit) but cut it progressively shorter until it runs in a nice gentle curve between the top tube stop and the seatpost bracket. Adjust that set screw on the bracket so that the inner cable exits in a nice line straight down to the brake. Clean the inner cable by running it through wire wool, then lube it very lightly with fingers wetted with a dry chain lube.

Or find something like this and fit it to the frame just above the stays:

Interestingly enough, the previous brake cable replacement I did (shown in the first post in this thread, and it was also my first ever brake cable replacement, so I'm a newbie to this) was deliberately done with the same cable lengths as used by the bike mechanics when they did it, so I guess they made the same mistake, @Globalti . Anyway, this coming weekend, I'll redo it with a shorter, less bending, cable outer.

By the way, do you have a shopping link to the above gadget? All I can see from the image URL is that it's sold by a Shop Uptown (Up Town?) Cycles.

A shorter cable outer will give you a straighter and more efficient cable line. There are plenty of devices on the market, I can't remember where I found that picture or what Google terms I used but you will just need to spend a few minutes trying different terms and trying the more specialised bike-builders' suppliers. However a frame-mounted collar would send the cable to the brake from the side of the frame whereas a traditional seatpost clamp mounted stopper such as you've got will at least be central, making brake setup much easier. Here's what you should be aiming to achieve:

It looks as if Surly make a longer device that will deal with your very elevated seatpost clamp more neatly:

Thanks, @Globalti , I really apprecate the information .

I nearly had a blonde moment and said water is maybe running in due to the angle then noticed the bike was upside down.

Sorry to but in without anything helpful to say but threads like this always make me question the oft quoted supposition that 'Everybody should learn to maintain their own bikes'. Some people just don't get 'it' and your attempt at re-routing the cable for the rear brake demonstrates that lack of basic comprehension of simple mechanical systems. Please don't take this personally, I'm sure you are a clever guy in many other ways but perhaps you should leave the critical bike maintenance to someone who knows and understands what they are doing, for safety's sake?

Thanks for that . Just for the record, I also deleted my reply to a previous post. The previous poster and I had a disagreement, but I see no need to dwell on it.
