Hey folks, guy with the toasted shoulder here. I was the beneficiary of great shoulder rehab exercises from posters, and they have been great, and I really appreciate all the input. Been off the rigid SS for quite a while, went out with it this afternoon, and got a great 2.5 hour ride in. What a blast! Problem is my shoulder is starting to hurt and stiffen already. Afraid I am going to have to steal the Reba from my geared bike. Question: can the platform give you the same flexibility to move between standing and sitting that is so simple on a rigid bike? Never messed with the platform too much--but I guess I will give it a shot if it can really work well. Any input is always greatly appreciated.
