No. I actually meant the actual grips that you hold that are attached to the handlebars.....if they aren't adjusted properly it can cause pins and needles and numbness.

Make sure these are adjusted...forward or back***....just a few mm's can make the difference!
As for the the handlebar height...that would more likely give him neck or shoulder pain.
Ah.......thanks.
It is a road bike........with drop bars.
I checked the tape and there is plenty of it -in good condition.
***I have suggested he shortens the front stem (if thats what its called) to shorten the "reach"
Thanks again.
