Hub size, any way around it?

[steve_sordy]

Apologies for this not being an e-bike specific question, but I know that most of you guys have had mtbs before and are a font of all biking knowledge. I'm hoping that you can help.

My grandson has a 1x11 Orange Five with a 142mm wide hub spacing and a 12mm dia axle. He has a medium frame and wants to buy a large frame and transfer all his kit across. The main problem that I can see is that the 2018 frame was designed for 1x12 and consequently has a 148mm wide hub spacing, still with a 12mm dia axle.

I know that his existing wheel will fit in there, and that I can probably get a new 148x12 Maxle to go with it, but can you get spacers to fill the 2x3mm gap? Or is this size misfit insoluble without a new hub?

The 142 standard is just a thru axle 135mm. The 148mm is boost spacing. There are hubs that have replaceable endcaps that allow the hub to used in multiple rear spacings. It is common to have a boost hub that can be used 12x148 thru or 10x141QR in the same rear 148mm spacing. 142 thru is the same spacing as 9x135. But I am not sure if there are endcaps that can make the 142 work in 148. You will have to check the website of your hub manufacturer.

Steve if your grandson needs the larger frame and new wheels are the only option, I just got wheels for my new hardtail build and they look good.
Available in 148 or 142 versions they seem like decent wheels and I can't buy the parts to build them myself for this price. It took me 26 days to get the wheels shipped from Asia. Not sure what your import and transportation issues are compared to mine in the US. But you might take a look for $159 usd.

@mike_kelly Thanks.
I have yet to look at the cost of a rear wheel.
I really mean HE needs to look, but he's 17 and paying for driving lessons and has just started his first full-time job. So as long as he doesn't spend all his money on branded trainers and upgrades to his surround sound games centre, then he can afford to do this. Grandad decided to stop buying him bikes when he got his first full-time job.

I hear you. Best way to learn to budget

I hear you. Best way to learn to budget

Not just to budget, but to learn to evaluate and assess specs, reviews, to use eBay and Google and so forth. Don't just go for the first bike you see etc. Quite quickly he began to see the value in replacing the medium frame for a large frame and transferring his kit across. He is bright enough, just unfocussed. If it was trainers, he'd be on it like a cat on mice!

I spent an hour or so today on the Orange website chasing down specs for every Orange Five frame from 2015 to 2020. The frame made a big change in 2018, but fixable. 2019 is the same as the 2018, but 2020 made too many changes. He now knows this as I sent him the raw data (but all in one place and easy to read). I set him the challenge to read it and feedback to me what conclusions he draws. I spoil that boy!

If he takes too long, he may lose that bargain frame and shock that I have found. Then he will just have to wait!

 

[mike_kelly]

I am truly amazed at how many don't or don't know how to shop for the best value. You see on sites like Amazon and Ebay that the exact same product might be wildly different in price from multiple vendors. Doing a little research will take your money a lot further.

[Mr President]

I bought this kit to do the same. Came from US company called bla k mountain or something like that

He can have this one if he lives anywhere near Monmouth UK

 

[Mr President]

Thinks there's quite a few kike it on ebay nowadays

Nowhere near Monmouth, but thanks anyway.
What you have done is to confirm that I can use a couple of 3mm thick spacers, which I assume are the two little ones in your pic above. But that big disc with the bolt holes (in which the bolts go I assume). What is that for?

PS: What is the search term that you used to find your kit?

Edit: That big disc with the holes is to go behind the brake disc, which needs offsetting by 3mm to line up with the calliper (now it's 3mm further away from the centreline of the bike).

 

[mike_kelly]

That disc is to reposition the 6 bolt disc rotor

Yes. Mike I'd right. You have to move the rotor out 3mm.

Try something like MTB hub boost conversion kit 142-148 in ebay

 

[steve_sordy]

@Mr President Found it, thanks for your help!

 

[Mr President]

@Mr President Found it, thanks for your help!

Have assumed 6 bolt rotors not centre lock.
If needed centre lock adaptors do exist, but harder to track down

 

[Ger@nio63]

Non sono neanche vicino a Monmouth, ma grazie comunque.
Ciò che hai fatto è confermare che posso usare un paio di distanziali spessi 3 mm, che presumo siano i due piccoli nella tua foto sopra. Ma quel grande disco con i fori per i bulloni (in cui presumo vadano i bulloni). A cosa serve?

PS: Qual è il termine di ricerca che hai utilizzato per trovare il tuo kit?

Thanks @Ger@anio63 At 83 pence, that is cheap!!. But I have doubts when I see that the items in question are 5mm thick, when I only need 3mm either side to bridge from 142mm to 148mm. Maybe that is why they are selling them off for £0.83?

 

[Mr President]

The 5mm x 15mm spacers are to convert a front hub to boost.
The 3mm x 12mm are for the rear.


Main issue I've had with Ali Express is the time it takes for orders to arrive, but given the price one can hardly complain. Just needs to be factored in.

The most critical component is the long brake rotor bolts. They need to be high quality. Alloy bolts don't cut it.

Hey, Steve.
4mm is quite a bit extra to try and squeeze in there.
Do you know anyone with a lathe?
It wouldn't be much work to carve out a couple spacers for a perfect fit.

I just searched my go-to industrial suppliers for 12mm ID spacers.
I can come up with plenty that are 5mm thick, but none that are 3mm. Odd, right?

A quick google search turned up this:

Thru Axle Spacers | The Robert Axle Project

6 and 12 mm spacers allow fitment to uncommon bike frames.

robertaxleproject.com

But spacers are spacers, and don't have to be bike specific.
Aluminumspacers.com has some that are 12.9mm x 19.05mm x 3.175mm

 

[Ger@nio63]

Hi Steve
as you can see they are of different sizes front 5mm rear 3mm you can also find an adapter to align the brake I mounted it in my 142mm hub it works perfectly

Chinese New Year starts tomorrow as well, so further delays likely.

OK, I confess, I didn't look any further than the top one. I was focussed around buying one only for the rear, which needs 3mm. When I saw 5mm, I (wrongly) assumed that was why they were so cheap.

Hey Steve,

when I look at the photos posted here, I think those adapter sets leave one issue unresolved. They ensure that the wheel remains in the center of the frame and that the disc rotors matches the position of the caliper. The cassette is untouched w.r.t. the hub. The chainstay (incl. derailleur) moves 3mm outwards in a boost frame. I am not sure whether there any adapters available for the derailleur. Perhaps the derailleur can be aligned 3mm further inwards to compensate for the new position of the chainstay.

Cheers, Thomas

Get some made,any engineering shop can knock some out for pennies,or,like me find a retired engineer with a garage full of lathes to knock out some

 

[steve_sordy]

@Mister cube The hub adapter kit arrived via Amazon yesterday for about £8. (see pic)

@WantAnEMTB You have identified a good point. I am assuming (hoping) that the limit screws on the mech are sufficient for the task. Because I am insisting that my grandson does all the work, it only gets done on Sundays, when he's not either working or playing rugby. So I have yet to discover whether the limit screws actually do have sufficient adjustment.

It worked OK with my mech. I guess the alignment to the chainring wasn't optimal, but I didn't notice anything
