Some people have expressed doubts about my sanity.

My latest creation should remove all such doubts.

Sweet bike! Interesting handlebars. How do you like the Rohloff? How is the pedalling energy
efficiency? Lots of drag?

I tried something like that a few years ago, just for fun, on one of my Frankenbikes. Lately, I'm
riding a road bike with 6" of steerer sticking out (with spacers and top cap, of course). I'm
dialing-in stem height before I chop down the steerer (darned threadless steerers!) Yeah, it's kinda
dangerous, and not recommended.

One of these days I'd really like to come over for a chat with the guru and see the collection.

I think that having to come off the drops to the flat bar just to change gears is a bit
in-efficient... could you not have fit bar cons?

Certainly no doubt where 'the chin' goes when on the drops!

Sheldon - how did you get two sets of brake cables to connect to the same brake? How does that work? - If successfull you could have a good invention for tandem stokers to use.

Actually, with all those handlebars, I'm left wondering if Steve Palincsar was onto something with
his insect conjectures in the previous "Sheldon's Metamorphosis" sub-thread ;-)

cheers, Tom

i dont know about how good it would be for a tandem stoker to have a brake, but i do know of two
ways to hook two levers to the same brake. the first is with a cross lever style inline device,
which effectively lengthens the housing at the inline lever. this means that one person would need
to use MTB two-finger style cross levers. or- you could make your own using the same principle
(basically, just make sure the cable travel comes out right)

another way is to use a BMX gadget that allows two cables to both pull one. its a simple but ugly
little thing that has two inputs and one output. when i wanted one, a few years ago they were fairly
tricky to find, but they are out there. ive also seen them on triathlon websites, although i dont
know what a tri-guy would use 'em for, exactly.

or, you could do what sheldon "theres no fooling us about his sanity" brown did, and hook up
independent brakes to independent levers. dont tandems often have a third brake system (like a disc)
to give the rims a break on heavy downhills?

All that bike needs is some aero clip-on bars.

If you're talking about the Surly-Rohloff demo bike http://harriscyclery.com/surly-rohloff, I
didn't. The bike has two sets of handlebars and 4 brakes, with one lever for each of the 4 brakes.

The Tektro direct-pull cantis are operated by the levers on the straight bars, the Avid disk brakes
are controlled by the levers on the drop bars.

However, I have, indeed set up a couple of my own bikes where there are two different levers to
operate the same front brake.

See: http://sheldonbrown.org/px7.html

and: http://sheldonbrown.org/otb.html to see my unique solution to this problem.

Yeah! If you've got both types of brakes you've gotta have more gears than that! Since you can only
shift from the top levers you could fit in at least 6 sprockets and a triple up front - these could
be shifted from the drops. 7 speeds isn't enough!

Either that or this new DA 10speed... Any way to shift to a fixed gear (w/o the derailleur idea,
obviously). Matt

Yo- read the page again. The bike's got V-brakes on one set of brake levers, disc brakes on the
other set.

Triathletes sometimes control one brake from two levers using a splitter:

DOH! Sorry for the dumb question; the text goes away when you click on one of the photos for a bigger view and I didn't notice the disk brake.

There used to be a guy around here with one arm and he had a road bike rigged with a lever near the stem that operated both brakes - different problem of course but it was interesting to see how he modified the bike to fit his needs. He was a decent climber but of course had to be careful on descents.
