Adult Bike adjustments for an 11 year old.
I've bought my 11 year old a new bike, it's a bit big currently.
The bars are quite wide at 750mm, and the stem is 70mm.
What is the recommended length for bars, they seem to be a lot longer than 'in my day'!
If I put on a shorter stem then will it mess up the handling too much for him?
Finally, is it possible to get a chainguard for the Stout chainset that is on it?
Is Chain reaction still a good place to buy from?
