Thanks. Yes interesting approach and amazing video from Nepal. Makes sense to do that although not entirely sure how one would go about targeting a specific part of the wrist to stop nerve compression but will look into it. As I said wrists have been fine with zero numbness for previous 2500 miles with flat bars which makes me think maybe something wrong with fit etc and I may not be able to solve it with this bike - eg shortest stem on / highest mounting position on steerer already done / bars and hoods rotated most within normal limits to use etc.
The drop bars are not a deal breaker as I love the bike and its a good fit with flat bars just a shame if I can't resolve with drops as would've been nice but possibly not an option hence my original post. Cheers
