I'm trying to find a cheap wheelset for commuting tires. I'm running tubeless on my regular wheelset, and I don't want to have to change tires. I would like to buy/build up a cheap wheelset with slicks for commuting, but my front end is the Fox fit with QR15. Is anyone running the adapters for these? Do they work ok?

I would stay with my old stumpy with the slicks for commuting and trainer, but I'm realizinng that it's just not sized right for me, and doesn't feel comfortable anymore when I compare it to the Tallboy. I also, would just choose to put the miles on the off road tires, but there's still my trainer time to consider as well. Granted for the trainer, I'm thinking I might be able to just use my 26" wheel with the slicks since I don't really need the brakes for that.

Thoughts?

I don't know of any adapters that convert the QR15 fork to work with standard 9mm QR hubs. What you will find are a number of front hubs with replaceable end caps that can be converted to fit your fork. Only certain hubs are actually convertible and each brand hub requires its own specific kit. Unfortunately you won't too many cheap wheelsets that are actually convertible to QR15, but you can have a budget set built with an affordable hub that is dedicated QR15 or convertible

It's not cheap, but you can convert a Chris King ISO Disc hub (the usual one used with a 5mm skewer) to QR15. You will need an axle and split ring spacer.

That's the axles for the rear hub, but the front looks similar.

This is from the website:

"We've got 15mm axles to replace your existing axle and convert to a ISO 15mm. "

Hope Pro II front hubs convert between QR and 15mm with just the end caps (they also can be converted to 20mm). Still not cheap, but easier and cheaper than the King route.

Thanks all,

It looks like I might go with the Hope Pro II for the front. I found one at Universal for about the same price as the Shimano 15mm, but I can actually find the statistics needed for spoke calculators for the Hope Pro II. Where I haven't been able to find them for the Shimano.

My hopes were very easy to convert. Most of my time was spent opening the packing for the parts. If you go with Universal you can get a pre-built wheel with a Hope Pro II cheap, but only in black.

+1 on the Hopes. They simply slide in & out with no tools.

this was a good read for me im moving from regular qr to 15mm qr on my front end also, but one question though are the hopes 2 compatible with maxle for the rear?

The ProII rear hub is available in and convertible between all axle types

Get a mid 80's road bike - convert it to SS on the cheap. This is what I did and it works really well. Don't care too much about it, didn't cost much (bike was given to me, seat, SS setup, bull horns and bar end breaks cost me less that $100 bucks). So when it rains and snows or bakes in the sun - I don't care.... There is one down side – it will lead you to have more bikes. I’m at five and working on six, which will be a Tallboy.

Oversize DT Swiss 240's (20mm) convert down to 15 and 9mm with easy to screw on adaptors that run about $30/set. I just converted a pair from 20mm down to 15mm. Takes about a minute. I actually used a pair of 9mm's so I could use a standard QR when lacing up the new rims-easier to work with in a truing stand.

Used to run Kings and Hadleys, but after a few years found the DT Swiss hubs to be a bit less work to maintain. Plus the rear hub can be converted from a 9mm to a 10mm to a 12mm Maxle quite easily. My rear is a 10mm with the larger RWS axle-makes for a super solid frame.

Pictures? Sure. How 'bout a giant one. Taken over the weekend right before the build. You'll notice the 15mm adaptors off to the side with the front set up with the 9mm adaptors. 9mm's press in, the 15 screw on like the 20mm's. Notice the 10mm rear QR.

Well, I have a 1990ish Stumpy, but the Tallboy is sooo much more comfortable, so I was hoping to pack it away in the garage attic. I'm starting to think that might not be my best option. I'm starting to re-think an extra set of wheels. For commuting, I don't have to have the slicks on, I could just pedal a little harder with xc tires on. That leaves the Training the only thing I need slicks for, and It's hard to justify $400 to 500 for a trainer.

Thanks for the input.

as QR15 is a standard and 9mm qr is a standard, any PLUG that goes into a 15mm hole and puts a 9mm hole where you need it should work. MAVIC makes just such a plug, there is no real reason you couldn't use it on ANY QR15 hub $13.20

At least in the case of Hope Pro II hubs, the 9mm end caps do not plug into a 15mm opening; rather, the 15mm end caps and 9mm end caps both fit into a larger opening, where the inner lip of the end cap contacts the inner race of the wheel bearings. To convert from QR15 to 9mm QR, you have to remove the QR15 end caps and replace them with the 9mm end caps, not just plug the 9mms in. I suspect them same is true of other convertable hubs.

I am here to report that Mavic's 15mm to 9mm conversion plugs work to convert a 15mm Shimano XT Centerlock front hub to 9mm. Thank goodness, because I didn't want to have to pay for new spokes and a wheel build to put on the 9mm 6-bolt XT front hub sitting on my shelf

Good to know. It looks like the Mavic adaptors have a small lip. Does that increase the hub width enough to need to spread the fork dropouts to get the wheel in?

This is the opposite of what the OP needed. He wanted to use a 9mm hub in a 15mm fork.

yeah, technically those lips equal probably 2mm extra width. But with my fork at least, I didn't feel like I had to force it to clear. It was more like "help" find the way.

I have a set of Giant P29 wheels at home that are just collecting dust and I could use them on my beater/around town bike. They are 15QR so now I'm wondering if they have removable plugs and if the Mavic adapter is the same size
