Big Dummy - Cable Lengths?
Hey guys... I'm wondering if anyone can tell me off the top of their head what lengths I'll need for cabling for the BD... I forgot to measure before I left home, and I wanted to pick housing up on my way home from work. If anyone has the numbers it would save me a round trip ;-) Otherwise I guess the build will have to wait just a smidgen longer before it's rideable...
Okay well if you get normal cables for the front and tandem length cables for the back you'll be in business. As for cable housing the front brake will be the same length as a standard bike, front der ~45" should be enough, rear brake & der ~75"
I just measured up my BD frame, but I don't have cables on it yet so these are estimates, but you should be fine as I left some fudge room in them.
That sounds about right. My rear brake and derailleur housing lengths ended up at right about 6 feet long each. Remember that if you use tall or angled-back bars to allow for longer cables. If you run something like a Nitto Dove bar the cables may need to be a foot or so longer than a regular mtb riser bar.
With my bad habit of cutting cable housing too short, I bought way more than I thought I'd need. I think that's why this is the first time in several tries that I got it right the first try. I picked up about 14' which left me with about 8' left over. But, it saved me from needing to buy more at 10:00 at night.
I used regular length cables and didn't have any problems. I even had to trim a little off.
Do you have Canti/V-brakes or discs? Are you running straight/riser bars or something with a pull-back like Mary, H, or cruiser bars?

Since I usually collect parts and tackle projects a night when the shops are closed, I don't mind spending an extra buck or two so I'm sure I can get the project done when I start.

Paul Canti brakes, for bars I'm using Salsa Moto Ace Bell Lap bars 46cm wide with Tektro road levers. Shifting is with Shimano bar end shifters. I've got a thread on here that I started with pics of my Big Dummy.

Like you, I prefer to have the stuff on hand, since being car free neccesitates a little more difficult trip down to the bike shop as opposed to just hopping in the car and running down there.
FYI, the SRAM standard shifter cable was long enough. I got a Tandem length brake cable to run to the rear disc and there's lots to spare on that one! For housing, I got 12 feet of shift and 10 feet of brake and that appears to be enough for running everything.
