Ok, as I start to assemble my parts list, I've got some questions. I may have to start a new thread if I don't get enough repsonses here.

Rims. I'm partial to Sun rims, particularly the Rhyno Lites, but they're porbably not the best choice for a recumbent. I notice Alex describes their X-101 and DA16 as "Excellent for recumbents". Can anyone offer their opinion, along with the reason they would choose one over another?

Hubs. I'll probably go with Shimano XT disc out back. I'm wondering what most people use up front though. I like the 20mm thru-axle front hubs, but that may be overkill.

Brakes. Again, I'm partial to Magura, but leaning towards Hayes, as there's a handy 2 into 1 adapter that will let me run both front hydraulic discs off one lever. Suggestions?

Shifters. SRAM appears to be the standard, due to their twisty grips. Do I go with X.9, or does someone else have a suggestion?

Thanks.

Also look at Avid disc brakes, and drum brakes.

Aside from grip shifters, the only other shifters I've seen are bar-end shifters. I wonder if it would be possible to attach rapid-fire shifters to a recumbent's vertical handles?? I think they'd have to be about 1.5" longer than normal for mounting, and perhaps bend inwards slightly.

I've got some Avids, but I've only seen the 2 into 1 for Hayes. Bar end shifters would be a step backwards in technology.

There are some trike manufacturers that use Avids and their own 2 into 1 cable system. Are you trying to avoid brake steer? I'm not so sure that an extra few pieces of metal would be any better at eliminating brake steer than two human hands. Though, you would be able to brake with one hand.

From what I've read on these forums and other places, some people prefer the bar-end shifters. One rider even replaced the grip shifters with bar-end shifters. How easy is it to downshift and brake at the same time with grip shifters? It can be done with bar-end shifters...

Fluid pressure will provide the equal braking that a cable system can't. I can get a lever that pulls two cables, or even make something that allows the the cable to run two mechanical brakes, but it will never be as simple as dual hydros.

I was hoping someone with actual experience with the shifters would offer their advice. By running the front brakes from the left lever, and shifting the rear gears from the right grip, I've eliminated the brake/shift worries.

Bar ends are IMO the best on a trike, with the way the handle bar sits in your hand they are in a perfect position to use and you can get a feel for which gear you are in,
I have ridden a trike with twist grip shifter and wasn't impressed (this was before I got the GT3 with bar ends, so I wasn't predisposed toward bar ends).
Normal setup brake wise for a trike is a lever on each handle for that side front wheel, rear brakes aren't required (under heavy braking there will be negligable weight on the back wheel, thus it will lock up easily and not help greatly) and if fitted should have the lever some where it won't get grabbed by mistake as it can cause a trike to swing sideways and flip.
I have read of several mechanical setups with brakes linked to a single handle and I think Green Speed sell a suitable handle.

Thank you for that info. What bar end shifters should I be looking at?
