I currently have a non-boost HT running a XT groupset with non-boost chainset.
I have a 142x12 rear hub. Can I use this ? http://www.velofuze.com/boost-hub-adapters/velofuze-boost-hub-conversion-12mm-x-142mm-to-148mm-boost-6mm/
Any UK source alternatives ?
And what does re-dish mean ? Is it expensive ?
Will the chain line remain the same as now with existing groupset ?
you have a non-boost frame and rear hub, they are compatible so what do you want the adaptor for?
We all start somewhere on the new bike standard timeline ay! 😛
Serious answer is you cannot go boost without new frame etc.
Sorry guys - the new frame I want is boost only, sadly.
Redish means having the rim moved across so it is in the centre of the now wider hub. The time is currently aligned with the centre of the 142mm hub. If you make the hub wider by adding spacers to the left hand side the rim is no longer in the centre. The redish fixes this.
Unless your wheels are something special it may be more cost effective to sell them and buy a boost set.
As for chainline does the new frame require a boost crankset? If it does then your existing one won't fit.
Thx a lot - should I assume that a redish cost about the same as a truing, which my LBS charge a reasonable £17.50 for ?
Nothing special about my wheels but they are recent and I quite like them. But the cost effectiveness does seem to lead me to new wheel(s) indeed.
The frame is 68mm BSA but I just checked and the full bikes come with a boost chainset as std so I assume I'd need to upgrade mine.
I am now finding this a bit absurd as I don't want boost as 2.35 is as big as I'd ever need... I might keep my frame actually now, far simpler !

Sorry I don't understand this. The frame ( https://www.commencal-store.co.uk/frame-meta-ht-am-650b-black-2018-c2x22586617) uses a BSA 68mm. The bikes they sell using that frame are indeed boost cranks fitted. Does that necessarily mean a non-boost crank will not fit or do you mean it won't yield a good chainline ?
I'd like to keep my entire drivetrain inc the non-boost cranks and was hoping this would be possible with the 6mm adaptor which is part of the Velofuze kit linked above. I thought 3mm adaptors each side would be an issue but I was hoping one 6mm on the non-drive side would leave the chainline intact as is (ie non-boost) even though the wheel will need re-dishing.
Whether or not you need a boost crank with a boost back end isn't actually about chainlines.
The two important questions are, will your chosen chainring(s) size(s) clear the chain stay and will the rear tyre foul on the front mech if using one.
If you are running an XT crankset with a single chainring that was designed for a triple ring set up you can sort of boost it by moving the chainring to the position of the big ring.
To save you spending £18 on a redish you could use this adaptor instead.
Thanks - my chainring is 30t oval, no front mech. Not sure it will fit on a different part of the crankset.
I had notice the 3mm x 2 Velofuze solution but I thought this would be even worse for the chainline.
I am so confused now and I apologise for being so thick.
Take it in stages. If your chainring doesn't foul the frame when you shift your cranks over to the new frame, then you are good to go with the adapters that keep the wheel centred (so no dishing required) like the velofuze ones - [url= https://www.mtbtools.com/product/adapter-set-rear-hub-boost-application/ ]mtbtools[/url] do similar sets. If it does and you need to run a boost chainline, then you will need an adapter set for the rear that takes the rear wheel all the way over to the chain side, like the [url= https://www.wolftoothcomponents.com/products/boostinator ]boostinator[/url] from Wolf Tooth.
ETA, as your chainring isn't the biggest, it may well fit OK, my 30t round went straight over to a Genesis Tarn frame but you really just got to try it out.
You are keeping a non-boost fork, so no issues there I assume.
Thx GS. Understood. I am quite confident the 30t oval will clear despite commencal keeping the same 68mm BSA BB widt as my current 2017 Meta HT frame (non-Boost), but time will tell.
On that assumption, the only thing I don't get is this in the 2x3mm kit description:
"“This adapter kit will keep the wheel perfectly centered and no re-dish is required but the chain line may not be optimal as the cassette will be moved towards the center of the rear triangle. “
Perhaps they're assuming I would switch to a BOOST chainline too ? (which I don't want).
The non-Boost Yaris are staying indeed!
I imagine they are expecting you will use a boost setup (ring or crank etc) just with the non-boost wheel.
I purchased a 6mm spacer and re-dished by 3mm, it didnt take long to do and has worked fine so far.
Shrink wrap over the spacer and original hub cap to keep them together is a good tip too.
Cheers. I guess you don't want to lose the spacer if you have a flat far from home !!
