Help with looking for wheels and hub/axle questions

Hi all

My kid has grown ever so quick its already time to swap over the 26 wheels to 27.5 (this is on a built MTB on the Brand X HT01 frame). The front fork is a 15*100 and the rear a 135QR and using a 11speed HG.

I’m having a look second hand to see what I can get, but it seems like slim pickings. That said I understand that some hubs can be changed to accommodate other axles.

I’m looking at one set of wheelsthat have the following hubs, I’d appreciate it if anyone knows and can let me know if they can be adjusted to work with my requirements?

Back Hub

Front Hub

Thanks v much for any advice/assistance!

Any help much appreciated!

I haven’t double checked but I’m pretty sure D711 and D462 are both boost size, so neither are possible to convert to non-boost widths 100 and 135mm. Where are you located? I think I have (new) 2x Superstar 27.5 rims, 15×100 novatec front hub, spokes, but unsure if I have a rear hub in the right size.

DT swiss 1900’s are still made in 27.5″ non-boost and all versions can be converted to Q/R.

M 1900’s are the all round trail versions and E 1900’s are the roughty toughty enduro versions.

Ironically both those are older standards so there should be bargains about. Have you tried a wanted add on here. Also look at 650b gravel wheels too

Oh and I think 10 speed and 11 speed are the same free hub for MTB.

EBay seems to have lots of qr rear wheels

But I don’t quite follow what the plan is. Your son has grown. Is this new wheels on his existing bike or building up a new bike?

Thanks for all the replies

I’m in West Herts. I’ll DM you to discuss more.

Thanks very much for that. I’ll keep am eye out for those.

He was outgrowing his 24″ bike, so and as a bit of a project we went with a 27.5″ XS frame and also put on 26″ wheels so it was nicely sized for him to start with. That way we thought we would get a couple of years out of the bike and we could move it up to 27.5″ wheels  for a bit of extra height etc. Then we could step up the frame and keep some of the same bits etc. Seemed to be several people doing that here on this forum and it sounded a good idea. But he’s grown like a weed so I need to source some wheels (and bigger cranks) now.

I have tried a WTD, but no attention as yet – seems pretty quiet on the classifieds.

Old-school thinking.

I’m 6’2″ and run 165mm cranks…, and previously we were all (almost) on 26″ wheels.

Sounds like it’s the frame you need to change.

And a couple more Novatech Questions as I’ve seen some others which are advertised; they have a D711-15 and he says are 15*100 and also a rear that is D772SB that he says is 142*12. I **think** the rears may be convertible to QR – is that right??

He was on 153 cranks, so was going to increase those to 160. He’s still within the overall range for the frame (which is designed for 27.5), but approaching the upper end, so I was thinking the extra wheels will allow that much more clearance to survive the summer. Then winter can be the frame upgrade!

How tall is he? If still in the range of an XS frame I’d expect cranks will be fine.

The sort of wheels you are after are prime 27.5 gravel sizes so maybe not so many bargains about.

So, I wrote that wrong earlier and now can’t edit – he’s on a 15″ S frame which is 5’3 to 5’7. He was only just 11 and a smidge over 5′ when he started on the bike last year – he’s know around 5’5 do I’d like to get the 27.5s on to help the frame last the summer and also change the cranks to a 160.

I can see why bigger wheels might be nice. But i don’t think they’ll change the “fit” of the bike

Its not to change the fit as such. It’s just that I originally undersized the wheels because he was slightly undersized for the bike (and young, so all weight saved will be beneficial). He’s now within range (although may grow out by the end of the year), so it makes sense to fit the sized wheels that are meant to be on the frame so he has the clearance from the ground etc he is meant to have and to make sure it does last him through to the upper height recommendation for the frame.

I am 95% certain both the rear hubs you have mentioned would need the same whole axle changing to become QR.

Which leads me to think you need this –

As you can see, i’ve got a box full and a load of 15mm front caps too.
So if you buy a pair of wheels drop me a message and you can have these for whatever the postage costs 👍

Thanks so much for the post, really helpful and very kind offer!
