Axle adaptors

I have a GT Grade with a 15mm thru axle front fork and crappy Alex Rims stock wheels. Just wanting to know if I got a new wheelset with 9mm QR hubs, are there adapters available to run a QR hub in a 15mm thru axle fork?

I went the other way, putting thru-axle wheels on a QR frame with adapters inside the hub (it'll be so worth it when the build is finished - new just brakes, rotors and a long cage rear derailleur to finish it off to make it into a stupidly quick and agile flat-barred gravel bike).

So I'd imagine it's possible to put caps in the forks / dropouts to enable QR wheels to be used. Whether or not it would be desireable from a mechanical standpoint is something else entirely - it feels like it introduces a weak stress point. As a matter of preference, I'd scout around for some thru-axle wheels instead, or switch the hubs over.

You can't do that the other way round as the QR hole wouldn't allow a Thru-Axle to go through it. You'd have to drill out your hub which is probably not advisable. You can only do it if the hub is designed for Thru-Axles/both.

Yes, but it's wheel specific. I know Hunt and Kinesis can supply different end caps.
My recommendation would be to buy either 15mm or 12mm thru axle wheels as 15-12 just requires a sleeve, and 15-9QR an axle. That way you've got completely future-proofed adaptable wheels. Sleeves and axles are cheap, £10-20 each

As above, I've watched a video showing how to convert Halo hubs and I think some Hope hubs can too.

Thanks people, something I just need to check for them when buying.

Some hubs can, you have to check when you buy the wheels.

It depends on the particular hub. Some hubs are designed to allow either thru-axle or QR with adapters supplied with the hub/wheel (e.g. I got some Prime wheels that came with adapters for both). If a hub doesn't have removable QR bits then you won't be able to fit a thru-axle through the hub.

Not normally I don't think, the normal procedure is to adjust the hubs to a different standard.  With the aftermarket Hunt wheels I have on my best bike - you can buy various kits to switch the hubs from QR to thru-axle.

Yes that’s what I was asking, if 9mm QR hubs can be converted to 15mm thru axle.
