Hi Matt, I remember reading about your accident last year. It stuck in my mind because I’d only just done something remarkably similar. I thought my injuries were bad but yours were worse. I was back on my bike, albeit slowly, last September. I too have vowed to keep my wheels firmly on the ground and thought I’d might never ride my rigid singlespeed again.
I only rode my full-sus for about 6 months and then gave the rigid a go. I’ve hardly touched the FS since. Riding it has been surprisingly pain lite. In fact the Jones bars are definitely more comfy than using the FS with normal bars. I think it’s the angle my wrist assumes.
I’d definitely support what Stevemtb and shinsplints said and see how it goes before rushing out and buying something new.
