+1 on fit.

Now, that being said, when I started riding my mtb a lot, like commuting 15miles, one way, I started having issues. I tried different hand positions, bar ends and still had troublesome wrist issues.

Having been a road bike rider and not having the same problems I did some self-analysis. My road bike bars were narrower (40cm compared to standard width mtb flat bars). Also, the significant part for me was the relationship of my wrists with the road bike.

My hands/wrists were in a more natural position, not rotated, when riding the hoods or drops.

So, in the end, for me, I swapped the wide flat bars for narrow road bars and my wrists have been happy campers ever since. I believe it is just what my wrists needed to be comfortable on a bike.

Of course, your solution and mileage may vary.

All the best in your search.
