[Closed] 20mm to 15mm front hub

It depends on the hub.

Some hubs have swappable end caps (eg hope) some don't. Post the model or a pic and someone will know. If not it's new forks or new wheel time.

Some 20mm forks can take a 15mm adaptor. Some older Fox ones I think.

New 110x20 or old 110x20?

What hub is it?

It's this wheelset

Doesn't come with adaptors
Fork is a Rockshox Revelation, I believe 2016

I’m going to say no, that cannot be converted.

They don’t list 20mm as an option and I’ve never even seen spares listed anywhere for them.

There definitely is a 20mm version of that hub, but whether it's the same shell or not I don't know

thanks all, I'll send them an email and see if adaptors are an option

I think orbital hubs have compatible endcaps as they use 6804 bearings for both 15 & 20 which are 20mm internal so I'll guess you just change endcaps, not 100% sure though.

Thanks - I was wondering about the bearing size - you are right, that will determine whether it is possible to 'increase' the axle size
Didn;t want to root around at the hub in case i need to send them back
Hopefully I'll get a reply

@endomick do they have an axle sleeve in there or something to accomodate a 15mm axle in a 20mmm i.d. bearing?

seems to be a 15mm axle sleeve in there at present

I had a 20mm orbital hub a couple of years ago that ran 15mm conversion caps, not sure the hub works the other way around 15 to 20, the boost one definitely doesn't, probably depends on the model year. My mate has some superstar tesla 20mm hubs, new unused in orange for £23 if you're interested.

Thanks for the offer, but if i can't adapt them i'll just send them back as they are brand new

Disappointingly, no reply from Octane One, despite a few emails
I probably could have got some adaptors made up, but as they were brand new opted for a return and refund instead
