A short stem will make the bike more twitchy, so will need to be combined with a wider handlebar to compensate.

Generally, for every cm you take off the stem, you want to add about 2 to the bar.

What bars do you have at the minute? I'd be tempted to start with an 80mm stem for xc/trail work.

Oh, just to add, the £30 on one cnc stem is identical to the £45 superstar zephir cnc stem. I have the on one in 70mm flavour and have had no issues with it-it just works. Light too. Also consider the KCNC offerings at clee cycles.

i have Ritchey WCS Riser Handlebar 660mm

I'd definitely try 80mm to start - look at Exotic stems too.

Cheap and light! And I've not had any issues with my 60mm one.

i allways like short stem 50mm i think short better for quick sharp turns at speed may be wrong but think i will try alonger one.

You can run a 50mm stem, but you should really be looking at getting at least a 700mm bar to go with that

Unless he has narrow shoulders - and as XC and trail bikes often have steeper head angles, a longer stem might suit better anyway.

My point was that if you go for a 50mm stem, you really need 700+ bars. If your shoulders or whatever dont allow you to have 700+ bars, a longer stem should be used instead.

i only need astem tyres and disc brakes then i will build iti have a meilt 3 frame that helps

I just don't agree that is true for all - for many it may help, but I know plenty who run shorter bars with shorter stems. It depends on so many things.

+ large potato.

It's what ever works best for the individual. There is no rule of stem length and bar length!
