Anyone done it? If so how? I did see one YT video where a guy simply used the axle from a boost hub and it worked. Would it be just that easy? Ordered a new single speed frame that is boost and I'd really like to use a Hope single speed hub but they don't come in 148x12.

Yeah...I guess the other issue is brake rotor needing moved out something like 3mm. Looks like the kit includes spacers and maybe longer brake rotor bolts. The video I watched the guy didn't need a spacer...I guess it will just depend on the frame and caliper. I could just use a regular hub and spacer kit but I kinda wanted to roll on a SS specific hub this time...not that I've had a problem with spacer kits on regular hubs. I thought the 88 POE would be nice and I don't really want to spend $400+ on a single speed boost hub.

Do you change ratios often? Have you considered a freewheel hub and a quality freewheel?

For example: $165 Paul Boost WORD (https://www.paulcomp.com/shop/components/boost-disk-word-148mm/) + $89 White Ind. Trials Freewheel https://www.bikeman.com/WIND-FWENOT.html

Tough to beat 72 POE in boost for ~$250. Cheaper than Hope once you include the boost conversion kit for the Hope. My WI freewheel has been fantastic. It is 10 years old and I have (shamefully) never done any maintenance on it. It just goes and goes. Only disadvantage is you need multiple freewheels or chainrings if you change ratios, which are more expensive than freehub cogs. I rarely change ratios so the freewheel option works great for me.

Not often but probably often enough I'm not sure I want to spend $90 per ratio change. But I guess it is an option to consider and I've never really heard anything bad about Paul hubs.

I'd do a search on Hope SS hubs breaking before committing, don't think anything has changed in the weak part of the exo-axle that the 12mm TA runs thru at the needle bearing interface. Fun bolt versions have enough metal but only 135mm axle. They sent me a steel replacement so my Hope 2 EVO is bulletproof now.

You can make the change on the chainring side, which cuts it down to $40 or so, but you will be limited in how high you can gear by chain stay clearance on your frame. I have changed ratios once in 10 years so I didn't mind buying a new chain ring. Al chainrings wear out much faster for me than the stainless steel freewheel anyway.

That sucks but thanks for the heads up.

I've been running the HOPE on a rigid steel boost bike for two years in tough conditions, and it works great. The kit HUB493 mentioned by another poster is what you need. Clear instructions; easy to install. For me it was a better solution than a freewheel hub, though the Paul and WI stuff is nice.

Bump.

I just bought a boost frame, and am looking to carry my SS/T hub with 142 spacing over. The only kits I can find in stock (because, COVID) are generic 'loose' spacer kits, and the Wolftooth Boostinator kit that is a 6mm "one side" spacer that requires a re-dish. I built the wheels and seem to recall the bracing angle was pretty great, I'm not sure I want to go moving the rim over to keep it centered.

Anyone done this? How did it go?

I have the Hope SS/T hub and it’s pretty great and I ride a lot and never have issues.
I have seen this topic about conversion to 148 before and I really don’t think that you have many options. Personally I think if I bought a new or used SS frame that’s Boost148 only I would just get a new hub. Lots of options available for SS specific hubs with Boost148. Onyx, I9, P321,Hadley, just to name a few.
What frame did you get?

So your advice is to *not* re-dish the rim?

Don’t bother with getting a conversion kit nor re-dish them. Just sell them or leave in your parts bin. Your going to be happier with a Boost148 SS specific hub. It will have wider flanges and end up being a stronger wheel.
What frame are you building up?

I actually found the answer. I'm so dumb, it should have occurred to me earlier. I just had to look up the hub dimensions on the Hope site. A 142 SS/T Pro4 has the same 32.5mm offset on both drive and non-drive side. A single-sided 6mm boost kit will actually make the non-drive side spoke bracing angle WORSE.
So that's out. I'll just use the 'loose' spacer shims until the Hope or MRP kits are in stock again.

Edit: I found the diagram in a desktop folder!
