Problem Solvers makes two different Cable Doublers. This one allows you to control two brakes with just one lever. Why? Well, there are myriad applications: cyclocross, fixies, tandems, bike polo, tricycles, recumbents, cycles for those with special needs, those four-person bikes you see on beach boulevards, and so on. You could even link them both together for ultimate redundancy!
Cassette Spacer 3.0mm Shimano/SRAM 8-speed spacer. Spacers for cobbling together or converting your old cassettes.
Sometimes socks-and-sandals doesn`t seem so wrong. Problem Solvers Decksters clip in to your two-bolt style clipless pedal and BLAMMO: a flip-flop pedal so you can wear your flip-flops. Designed for Shimano Mountain, Crank Brothers, Wellgo, Ritchey and Time pedals. Sold in pairs. No cleats included.
When converting a frame with vertical dropouts for use with a singlespeed, fixed-gear or internal hub, there's often a derailleur hanger left out in the cold. Problem Solvers stainless steel plug fits in there nice and snug and protects the hanger threads from dirt and grime. Problem Solvers put the 4mm broach on the bottom of the bolt (not the head) so that it threads in from the inside for a clean, finished look on your drive-side.
Mounting electronic shifting systems challenges the most prolific of bike mechanics. When small frames, recumbents, or adaptive cycles are involved, the standard battery mounts don't accommodate. This mount accepts the small Di2 or EPS battery mounts and comes with zip ties to attach that battery anywhere on the frame you need it.
