I'm seriously considering the new Bronson frame. I have a Nuke Mega AM as a donor for the project if I go ahead. I see the Bronson has a rear axle spacing of 148mm? My mega is 142mm I think. Is it a simple matter of adding spacers or something like this or do I need a fresh wheel?
Hub dependant, think hope do a kit
New hub at the very least as 148 is a different hub shell width, not just axle length iirc
That's more than likely a new wheel or hub and rebuild I'm afraid.
Whole new hub I believe. Irritating, a conspiracy to get you to buy the whole bike I'm convinced!
Who needs standards and inter-compatibility. 🙄

It is but it's also just a way of holding the wheel in the middle, AFAIK the hub is wider and the shell but a 142mm can fit with spacers and perhaps shimming of the rotor - I read something about hope doing this, you just drop the milipercent stiffness upgrade.

Ah. As I suspected then. Still not a deal breaker. Just irritating. Is the old Bronson 142mm? Some bargains out there. Could be worth considering?

might as well spend another £3k to avoid rebuilding a wheel 😆

no one, unless your changing your frame every week what is the issue? so you have to change a hub hardly a massive deal considering you could have the frame for 2/3/4 years

your ruler is miles out

LOL I remember a former colleague measuring stuff on the screen in autocad... we laughed for quite a while
ANother thing about boost is that it changes chainline - SRAM recomend a different spider for their cranks.
Dunno what you do with Shimano, as they have no replaceable spider, suppose you can muck with spacers if it's an external BB, but not ideal otherwise. Do Shimano have boost-chainline compatible cranks? Or is Boost a whole new way of forcing them out of OEM in favour of SRAM?
If you have a Hope hub they have already said they will make spacers for it.
They already make rotor spacers as that's changed too, as it will need to be spaced an additional 3mm outboard, due to hub changes.
Hope are making spacers for front only IIRC.
Spacing axle, disc and cassette out back might not be doable
Do Shimano have boost-chainline compatible cranks?
Yes, they do
Wow this really is a cynical move by SC / the industry. So the 5010 and the Bronson get 148, but the Nomad stays on 142? Also I have enough trouble with ankle rub on 135 & 142, this will be even worse.
I was ready to pull the trigger on the new Bronson but will re-consider now. This constant "standard" change needs to stop, it is just wasteful. I still haven't decided what to do with about 20x 26" tyres in the shed, probably just bin job.
Hope they lose sales on this.
Its a PITA as there are not many 148mm boost hubs available (at a reasonable price).
I'm looking at hope Pro 2 for a new 5010 build.
I would wait for the new Hope Pro 4 but i'm itching for a new frame.
DT Swiss 148mm don't seem to be available until December.
