Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

SRAM Cable Routing?

Installing my first SRAM setup and was wondering how most people run the cables, brakes on the outside of the bar and shifter on the inside, or double them up on the outside?

I doubled mine up on the inside. the cable housing then creates a bump that conforms to my hand more when it's on the inside of the bar.

One cable is behind the bar, one cable is in front. Kinda makes it winged. Do whatever feels/looks right.

At least with Shimano I didn't have a choice

Right now it looks like one behind (shifters) and one in front (brake) will be the easiest way. The bar has two grooves on the front and back.

I guess I can always re-route if it doesn't work out.

I like to run the shift cables behind and the brake cables underneath. My bars are pretty low and if I run either of the cables in front they have to take a sharp bend to get anywhere...

I'm preparing to do a full Rival replacement of existing Ultegra components on my new bike, and I have one of those DA in-line gear counters that I want to install. If I kept the Ultegra, the gear counter install would be easy - anywhere I want after the cable exits the right shift lever. But since it's Sram, I have to install it just after the cable exits the bar tape. That's the plan, but not having experience with Sram, I don't know how the cables exit the bottom of the shift lever and how seamless it will be to reverse the normal routing of brake cable in front, shift in rear of handlebars. I want the gear counter in the front so it's easier to read.

Sram says the following about their '09 Rival levers:

"Added cable routing options allows for both brake and shifter cables to run along either side of the handlebar."

I'm guessing on the shift lever unit there are two holes at the base - one angled toward the left (brakes), one toward the right (shift), and no way to choose which holes run which cables. Then it's up to the individual to decide how those cables are run from there. If both go along the front of the bar, then there will have to be lump either on top or below as the shift cable crosses the large part of the bar instead of running in the groove. To avoid a lump where your hand sits anywhere near the hoods, the ideal way would be to run the shift cable under the bar to join up with the brake cable in the front groove. But I want the shift cable to run above the brake cable so the gear counter will be visible as the cable exits the tape, and that means routing the shift cable above the bar as it exits the shift lever. Hello lump.

So I've come up with the idea to place additional strips of bar tape alongside the shift cable as it runs across the top of the bar to lessen the impact of the lump. I have used double layers of tape in the past to help absorb road vibration on my hands and wrists, so some creative tape layering might help reduce the impact of that cable lump.

Oh wisened cable masters, your thoughts on this would be most welcome. Below is a mock-up pic of the desired result.

I'm not sure if that would even work as the SRAM shifters move a different amount of cable than the Shimano shifters, that's why the RD is not compatible...

I spend so much time on the tops of my bars that having a cable routed up there would drive me batty, even with extra layers of tape.

FWIW, my first bike had the Shimano Flite Deck computer with gear indicator. I thought it was invaluable until I didn't have it anymore when I switched to Campy. I don't miss it.

Both cables in front of bars. Shifter housing crossing to bosses then cables cross again under frame to compensate. Reduces some bend and prevents a lot of frame rub so I like it.

Good point, but for my purposes, even a close proximity will help. After a period of using it, I'll know the red dot alignment.

My rides are rarely on flat routes these days, so there's a lot of shifting. With 10 gears, knowing where I am without looking back at the cassette is important. Having ridden my new bike without Flight Deck for several days now, I'm doing alright, but I'm not as focused in terms of accomplishing workout goals. Knowing what gear I'm in helps on familiar (daily) rides, and matching or beating previous times.

much safer to just glance at the gear indicator than have to look behind at your cassette to see what gear you're in.

Actually there's one place to put the brake cable and then the shift cable can exit from one of two locations: on the left or right top corners where the shifter meets the bar, more or less. Therefore you just choose which of those two through which to route the cable and there's no lump.

Aha!!!!! Thank you! Now I can get back to work and stop thinking about it. I owe you at least a beer.

This how all BF inquiries and issues should be resolved.

It won't even be close.. SRam cable pull is about 2x Shimano. So the dot will be hitting the end of its travel
and letting the cable slide through it, then following the cable when you shift the other way. It will be changing
position on the cable.

I don't understand why you guys can't figure out what gear you're in based on:

1. what gear you were in.
2. how fast you're going at your cadence.

On top of that, why is it such a big deal that you have to "know"?

Besides, don't you all just ride in just the 53x11 like I do?

I was afraid of that. OK, so I'll just have to make my own. I'll need a glass or hard plastic tube of the same diameter... Yes, it's that important to know what gear I'm in. Here's one reason why.

On a climb last week with the new bike (sans FlightDeck), I was struggling up a particularly long and steep section with the rear D already in the lowest gear. Without knowing for certain (no indicator to tell me), several times I thought I had one more gear to go and instinctively pushed the lever, only to feel it maxed out. That simple effort was enough to break focus and get me thinking about crap I don't need to think about. With one simple glance at a gear indicator in my line of sight, I'll know there's no additional gears. Or if there is one.

I ride and climb much better if I have a full array of guages, dials, levers, pulleys, buttons and switches in front of me. That's how I drive my car as well, with three vdo guages atop the dash (manifold pressure, oil pressure, oil temp) and three below the dash (battery guage, water temp, outside temp).

You're from Florida. Here in CA we have different rules of engagement for cycling. Mostly because of hills.
