pins and needles

[Regional]

I have loaned my friend my MTB with a view of selling it to him but he is complaining that the 13 mile ride to work is giving him pins and needles in his arms.
what could it be?
Would the handlebar height have anything to do with it?

It's a 19" frame which should be ok for him (5' 7") and the seat height is correct, i can only think its the bar height.

Any thoughts are welcome

Isnt 19 inch a large frame?
5ft 7 is for a medium frame at the most!

19" is large on MTB? ok then but then surely the bars would be higher if the seat was low down?

I'm 6' 2" and the bike was always on the smaller side for me although thats how i preffered it.

whether large or small frame sounds liek a geometry issue to me, possibly over stretching therefore putting too much pressure on hands which is manifesting itself as pins and needles in the arms...........if it is forearms could be bent wrists..

Definitely a geometry issue as noted. Frame does sound on the large size for a shorty; the seat and bar height can be adjusted a fair amount each but the length of the frame will be too long (and only slightly tweakable via stem length).

If it's a laidback seatpost, can he not rotate it 180 degrees, granted the seating position will feel a little odd and he'll get some funny looks but it could be a temporary solution.

Could also do the same with the handlebar stem.






Sorry, I'll get my coat.

i have also thought about brake/gear lever positions, as i was taller i had them positioned further around the handlebar - if the shorty was having to rotate his wrist further then surely that would cause some discomfort?
He is going to raise the headset and see what happens.
