IMO it depends, some people dont feel a single thing, other ones u move them 1 mm and start with a bunch of problems. You have a numbess problem, as somebody said, maybe is a problem of too much weight in the front of the bike, or is a thing of how you grab the handlebar. Or even the stem too low.

Wonder if you have the nose of the saddle too low, then the weight will go to the front of the bike then the hands might get numb. Who knows, hard to tell w/o seeing the bike my friend (pictures).

The easiest thing to do is move the saddle back a couple of mms,... to use gloves or even could be that the handlebar doesnt likes you, have seen that to happen aswell.

I have a carbon handlebar that gets my hands kind'a numb for some reason, what i do is to change position over the handlebars and problem solved but i dont even use gloves so probably thats the issue. Have a bike with a cheap @ss FSA handlebar and those ones are just perfect, never a single problem. Not all the equipment works for every rider.
