Anyone upgrade their B21 seat with something better? I am interested most in stronger suspension system and possibly arm rests, but I suspect the B21's TLB spin seat system and/or mount may not be easily upgraded with aftermarket stuff. Thanks,
I had a B21 for six years and spent 1800 hours on that thinly padded piece of steel. I traded the B21 for a B26 three years ago and the seat on it is a huge improvement. I would think you could adapt the B26 seat to fit the B21.
