[Closed] 26" wheels and XS Frame (Too big for a ten year old)??

My 9 year old is riding a specialized 13" frame with all my old bits on, pretty light and 1*10 with a 30T up front. Cranks are 155, Thorn ones. Even got him to help build it.

Depends on the size of the boy but should be fine. As mentioned above some short cranks will help massively.

I'm not sure all 10 year old's are the same height...but with a slammed seat, short cranks and stem and narrow bars i think it'd fit just fine.

I'm about to move my 'taller than most ten year olds' 8 year old up to a 24er / 13" frame because i have one lying in the shed. I don't kids are that fussy about sizing tbh. Soft seat and grips and some skull stickers are where it's at.

Great advice guys - thanks. Never thought about crank length tbh. And yes letting him help build it makes it even more special. Brilliant - off to search for an XSframe. Cheers all.

Last year i built 2 bikes up for my eldest pair.
1 of them being a medium spesh pitch for my then 9yo and 5'1" daughter
The other a short scott voltage fr for my then 8yo 4'10" son

Both run 1x10 11-36 cassettes with 30t NW ring up front,152mm cranks and 40mm stems.
Neither of them struggle for reach.

Thump - 10 soon - razzes around on a 14" Kona.

XT 9-speed castoffs. He started with 150mm cranks but have just moved him to 175mm cranks (2x9) which meant a lower gear and suited him better.

Loves it!

Our 9 yr old went onto a Genesis Core 20, 14 inch frame 650b, a few months ago. Fits him well and he loves it. High front end but not an issue when riding (stem has a few spacers above and is inverted)

mines on a 14" patriot with 24" wheels.....just a tad too big but copes fine on the rough stuff

Surely depends on their height? I'm 4ft9 and 14" bike is just small enough. Shorter cranks, not too big tyres give you a couple of cm. however riding is bike that is too big sucks. If you live anywhere near Sheffield I have one in my shed you could try.

I'm currently building an XS trek FS frame up for my 8 yr old.
It's running 24" wheels, 100mm travel front and back with150mm cranks and a 35mm stem. Not put him on it yet, but sizing seems about right from the measurements I've taken. I'm keeping the wheels as light as I can, and the components as compact as possible. The plan is to change up to 26" wheels, longer stem, seat back etc: when he outgrows it.

I did this, but put on a pair a 24" wheels for a couple of years first.

hmmmm, lots of food for thought. Thanks for the options all, and the offer evh22 (Im in the SWest which is a shame). He's 5ft and his current cheapy 24'er has a 14" frame and he's getting very very confident on it. Think I might take the plunge on a 13" 26er and keep things light and simple. 152mm cranks, 30t 1x9, short stem and some choice grips! Will post pics when up and running. He's well excited just talking about it ( a bit like the grown-ups I guess) 😆

My 8yr old is on a xs 26er. (13" iirc). Fits well. Running 150mm thorn cranks, 80mm fork, 30t ring.

A good guide is the islabike range. Compare to that for frame geometry, wheel size, kid height etc reference.

Skyliner: at 5ft he should be fine on a 13 or 14" bike. Probably won't need very short cranks so I wouldn't buy specially. 165mm would be ok and he sounds like he's gonna grow tall (and probably soon!) and need a bigger bike in a year!

My 4' six year old rides a 24 ... Can't see how a 5' ten year old wouldn't fit a 26 small (13"-14")

I'm 5ft 3 (just about) and I tend to ride 14-16" frames - it depends on the brand. A 14" On-One Inbred or Orange 5 is fine for me, 16" is too big, but a 13.5/14" Trek or Specialized is too small (I currently ride a small Stumpjumper FSR, which is about 15.5/16".

Great info all - looks like the way to go - cheers!
