Put is this way.....I have had 4 V10's and all have been larges. I would not ride anything smaller. It's a perfect fit. I tried comparing TR450's to the V10's and it doesn't compare. Even though the numbers are similar the V10 feels better at a large.
Don't know if my last comment went through.....but I have had 4 v10's in the past and all have been larges. I wouldn't ride any other size. Medium is way too small.
