Does size matter?

[AdrianXavier]

Thought a catchy title might get more responses....
Bought my son a new bike for Christmas and now I’m worried I got too large a frame.
He’s 12, a little over 5’4, likely coming into a growth spurt in a few months... but now he’s 5’4”. He’s getting a Scott Scale 980 29er. Size M.
Scott sizing chart I just found says M starts at 5’7”. Can I have the seat post cut off a little? Should I? He’s riding an old trek 820 26er now. I’m afraid I’ve made too big a jump. Someone talk me off the ledge. Or tell me if I’m screwed.

So many factors, but I would say that a medium will be big, but depending on his growth and your weather, it might fit by the time that the trials are good again.

IANAL, and TINLA.

I would not cut the seat post down at all before I contacted the manufacturer to see what the specified maximum distance of seat post can be removed (provided that they allow any modification at all) or what the minimum length of post must remain (or most likely a minimum seat post length ) and also call your local legal expert to check any local laws, ordinances, statutes or any other type of case law that you can base your (hopefully) informed decision on.

As I read and re-read your question I have to admit that I've become quite concerned and quite frankly i'm a little shocked that the desicion you'll make for the safety of your child is being left to an internet message board full of anonymous strangers, while at the same time creating a situation where anyone who decided to answer your question could be held liable for anything that may happen as a result of this conversation. The CN forums have had a forum rule for a few years that specifically forbade soliciting these boards for any form of legal counsel, medical opinion or financial advice, as well as other professional services. I will close this thread per forum policy and ask you politely to refrain from posing another question of similar substance.

TIA for understanding.
