I've made almost every mistakle possible when deciding to upgrade some wheels and find myself with a front Hope Pro 4 hub at 100x15 with a Fox 36 BOOST fork at 110x15
What's the best way for me to sovle this issue do we think?
Cheers

I had the same issue when using my parts bin to build up a frame. I bought a front wheel "boost" kit from ebay and superglued the spacers to the ends of the hub. Fitted the six bolt spacer for the disc brake and it works great. I used the thru axle to keep everything aligned and small dabs of glue so they could be knocked off again if necessary.
I used to just use the spacers loose but when taking the wheel out they can fall off and roll so could be lost on the trail if doing a repair so decided a bit of glue would solve that problem.
Alternatively…Looksy here…
None of those options do what he needs. You can get boost conversation kits on Amazon/eBay though
Apologies, have pasted the right link to the right thing now…I think…
easiest to install and to live with is the MRP Boostinator, but you pay for the convenience.
easy to live with but complicated to install is the hope or wolftooth style, but you’ll need to re-dish your wheel.
easy to install but potentially frustrating to live with are the spacer kits where you have the potential to loose the spacers every time you remove your wheel.
i have MRP on the front and Wolftooth on the back, so that is my recommendation.
@dallas95 if I do end up converting I think I will likely glue it, good idea
@donslow it's 32h and silver unfortunately
that conversion spacer looks to be the solution, what does redsihing a wheel involve? I've neaver even heard of that before lwt alone done it
@LAT does the MRP Boostinator involve a redish do you know? Looking around I've also read that they can't be used on the front with a rotor of anything larger than 183mm but I can't find anything on the offical site to confirm that
If you’re only going to use the wheel on boost forks, get the Hope booster end cap and dish over. It’s just nice and easy. The little spacer ring solution is fine, I used it for a while, but if your wheel can take the dish it should actually be better because the spoke angles are nicer. I built up an old Hope hub this way with a light rim and the spoke tensions are almost perfectly balanced- probably the easiest build I’ve done.
dishing the wheel is centring the rim between the ends of the axle. the conversions that replace one end cap add 10 mm to one end of the axle, this means that the rim is no longer centred.
to centre the rim you need to loosen the spokes on one side (the side with the disc in this case) and tighten the spokes on the other.
the danger is that your spokes may not be the size that will allow you to loosen/tighten them sufficiently.
if you aren’t into heavy fettling, it is a job best handed to someone who is.
@brutaldeluxe09 as far as I know, re-dishing is just centralising your hub to your wheel/rim after installing such kits as the one I linked
As far as I know (again) it’s a 10 minute job of playing with spokes that most bike shops will charge very little to do
Happy to be corrected if I’m wrong…
the MRP doesn’t need a redish.
@swanny853 are there any gains to be had from running a boost hub over a conversion of non boost to boost? or even wilder would it be madness to consider abandoning the concept BOOST altogether shoudl I be considering a fork upgrade anyway? It's been a while since I've had a bike and coming back to it so much has changed
You only need a re-dish on the back wheel as you need to move the cassette relative to the disk. On the front you need a 3mm spacer each side of the axle and a 3mm spacer under the disk mount.
Supposed benefit of boost is it makes the wheel stronger (bigger triangle with hub/rim/spoke) but for most riders that makes no difference.
@stuf I assume the trade off is weight though the wheels come in at the same weight looming at it, would BOOST forks be subtanially heavier? It all seems a bit too much to me this BOOST idea at the moment
It is 2x 5mm + 5mm disc spacer or 1x10mm on the front, 2x3mm +3mm disc spacer or 1x6mm + 6mm disc spacer on the back I think.
I would go for the Hope boost end caps and re-dish the wheel, you get more even spoke tensions that way.
@LAT I've for now gone with the Hope spacer that will require the redish. Do you know how to tell whether the spokes are good for it?
@greyspoke yep went for Hope spacer in the end and will get a redish done. Cheers
@StuF the benefit of the hope longer right hand spacer and a reddish is that no disc spacer is needed. If your only ever going to use the wheel boost then this is a better solution than running a disc spacer.
@brutaldeluxe09 spokes will almost certainly be good for it. The difference in length is minimal. I've even reused spokes from a 142 rear hub on a 148mm hub. The difference in spoke length was <0.5mm.
As Nixie says.
I have a front Hope Pro 4 with Arc40 rims on my plus bike.
Originally was 100x15 and bought the Hope adaptor to boost.
30 minutes later with the wheel in the fork and bike on a bike stand, the wheel was redished and centred.
I used evenly sized bits of cereal box taped to the forks to give me my central aim, then went round one side, loosening 1/2 turn and tightened the other side the same 1/2 turn.
Did this in stages to avoid making it too wobbly and I think it took about 3 tweeks per side to get it centred.
Have changed it back and forth between forks at least 3 times since and it's remained true after each adjust with no problems.
" As far as I know (again) it’s a 10 minute job of playing with spokes that most bike shops will charge very little to do "
I was quoted £90
Boost hub makes for a wider triangle base for the spokes. Boosting a normal hub to the disc side gives you a more balanced triangle. I wouldn’t claim to be enough of an authority on wheel building (by any extent!) to actually tell you which is better, but my lightweight boostified wheel has been really stable- no love required
sorry, just seen your question, but see it’s been answered.
I think boost was introduced to make existing frames, forks and wheels incompatible with new stuff. i am mostly over my rage, but will not buy a trek bike as a result (trek introduced boost)
