Swapping out my standard handlebars with Nashbar's Trekking Mountain Bike Handlebar. My hands get numb halfway through my longer rides so I'm looking to open up some more options for placement. The thing is, I bike through some heavy traffic and alot of 90deg driveways. I recall my brother's old 10speed (from the 80s?) had 2 pairs of brakes, I'd like to add a second set of brake levers to accommodate the new hand positioning but don't know how.

I've added a rack and changed the OEM knobbies to a pair of Serfas Drifters. Everything else on the bike is stock

Q1: What do I need to be aware of, what tools do I need in order to add that second pair of brake levers?

Q2: Any manufacturers to AVOID when looking at brake levers, cables etc?

Thanks in advance
