    adapter 15mm to quick release

    I have an adapter that goes through my 20mm hub to be able to use a standard fork and skewers does any one know if this is available for a 15mm hub?

    that isnt possible.
    20mm hubs are wider than standard hubs. the adapter you have is for trueing the wheel only.

    Unless he's talking about different end caps. Then it's possible.

    Shimano doesnt make a hub that will do that.

    That's true... forgot which forum this was in. OP didn't mention hub brand, and I didn't think about this being the Shimano forum.

    Many other manufacturers do make hubs that are a super easy conversion.

    15mm hubs are designed for a 100mm spacing and 20mm hubs are designed for 110mm.
    the brake rotor wont line up either.

    15mm to 20mm?

    Can I convert my shimono 15mmQ to a 20mm? Thinking of going to a Vanilla 36 for the 5spot.

    Ben

    Both are 110.

    9mm QR/TB/BO is 100, but both 15 and 20mm thru-axle are 110mm.

    Unless I'm very mistaken, the only 20mm compatible hubs from Shimano are the ones that come as 20mm to start with. The 15's use a smaller hub shell that can't be converted.

    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

    Does anybody know if this works on bontrager 15mm hub (Bontrager Rhythm)?
    Does bontrager have such adapter 15mm->9mm?

    chameleoneel, was there any problems with increased width of the hub? does it normally fit into the fork?

    those end caps are for using in a trueing stand. NOT intended for riding.
    they are not safe.

    These appear to be the same end caps that came stock on the previous generation Mavic Crossmax ST 9mm/15mm wheelset. On the ST they were intended to be used for riding with either a standard 9mm QR or 15mm fork.

    Geeze. Just get the right gear and quit playing around with BS conversions that diminish the performance and safety of your gear.

    Since the 15mm and 9mm axles are standardized, it looks like it will work on any 15mm hub as long as the end caps are long enough to contain the adapters. But the only way to know is try.

    How are people getting on with those Mavic QR plugs? Just about to buy some as I've picked up a very cheap 15mm thru axled wheel.

    Thanks

    They won't work on the wtb hubs. The hub itself is already the full 100mm wide and these caps add a few mm's on either side

    Are you talking about the WTB 15mm compatible front hub, or the 20mm compatible front hub?

    My hubs are the wtb laserdisc lites, I believe, with a 15mm thru. Basically, if the hub slides into a 15mm fork and doesn't have removable adapters/ caps already, I don't know how the end caps can work. The inside width of both 15mm thru hubs and 9mm qr hubs is 100mm. The magic end caps add to that, making the hub too wide to fit in the fork.

    I have a Giant SXC2 29er 15mm that I want to convert to 9mm QR so I can run it on my SS. I would need an adapter that fits flush with the end caps or new end caps. Any suggestions?

    Looks like they'll be good for use in bike rack wheel holders which are easily spread rather than hacking things up. Need to get a set.

    the magic caps add about 1mm, the edge is very thin, it's there just to prevent you from pressing them in too far.

    all 15mm hubs are already 100mm wide, i have used these adapters successfully on quite a number of hubs, hope, shimano xt, in fact the only hubs that are confirmed not to work so far are probably dt swiss because of a specific design of their unsupported 15mm end caps

    the only design that does not work is dt swiss' unsupported end caps because the 15mm end cap is only used to preload the bearings from the side, you cannot put any weight on it from above, which is what the 9mm conversion does.

    but if the end cap sits on an axle that goes through a larger bearing or if it is directly part of said axle, which is how most hubs work, you'll be fine

    Been running the Mavic plug in converters in a 15mm XT front hub for the past few months without anything nasty happening. They seem rock solid.

    Mavic adapters are only for mavic hubs. Please don't try to force them into other hubs. You are forcing 4mm extra into your fork causing them to expand outward. Hub plus caps = 104mm+\-1mm. I don't know if it's safe but I have a set of mavic cross rides and a set of bontrager dusters. Both the hubs are 100mm spacing but the mavics have a inside diameter beveled edge to accommodate the mavic adapters. You'll have to custom make an adapter for any other 15mm hubs. I had to make one two yrs ago for my dusters and it works flawless.

    Wouldn't there be lots of muck getting in between the bush and the hub causing wear?
    I have just got a 15mm thru axel XT hub with Stan's rims and am looking for a way of putting them onto my forks without having to buy new ones and as QR. The forum so far has been very informative!!

    If you're running an xt 15mm thru hub i don't think you'll need a bush as well.

    I'm a little bit late to the party here, but I am considering buying these plugs for a stock Giant wheelset. I think the hub is likely a formula hub. Has anybody had any issues with the slight extra width these add? Any experience with Giant branded wheels in general? I will just be using these adapters for a rigid steel fork.

    No issues here. Theoretically all QR15 15mm hubs share the same hub width. I used them for about a year on a set of XTR Trail wheels with a Fox F120 Float fork. You notice a little more friction against the dropouts when removing/installing your wheel but otherwise just fine.

    What about one of these adapters from Ebay seller mtbtools?

    No affiliation or experience, but it seems like a reasonably priced solution that won't spread your fork unnaturally.

    These look very nicely made but likely a bit heavier than the Mavic adapters. I've purchased a headset press made by this eBay seller in the past and it was good quality.

    As far as the unnatural fork spread, when I was using these, I noticed a little more friction against the dropouts when removing and installing the wheel but nothing that would lead me to think I was stressing the fork lowers in any dangerous way.

    Hi, I'm looking for adapters to reduce my 20mm front Bontrager Rhythm Elite hub (off Trek Remedy) to a 15mm.

    Trek offers a kit but I was told it is $50.00 and I have to have a shop order. Anyone have any other suggestions or know who makes the Bonty hubs?

    Thank you,
    John

    I tried the Mavic adapters in my XT hub but ended up purchasing the full length alloy axle on ebay from mtbtools, and have to say it is very light at approximately 45g, nicely finished, and fit perfectly. Highly recommended. There is a similar axle sold on the Ritchey Logic website, except it is necked down in the center to reduce weight. And chainreaction is selling one made by Nukeproof.

    I am surprised that some folks are using the Mavic QR adapters in their XT 15mm thru axle hubs, because they did not work well with mine. The XT hub’s axle is 96mm long and the right side locknut makes up the difference so the assembled width across the hub from the left face of the axle to the right face of the locknut is 100mm. The left side Mavic adapter fits nice and snug, but the right side has to reach in 4mm before it makes contact with the axle, just enough so the o-ring doesn’t seat and the adapter can wiggle around and fall out. Of course when you have the skewer holding the whole thing together the adapter is trapped between the fork and the hub and can’t go anywhere. I rode it that way and the adapters worked, but I just didn’t feel very confident in them.

    I've got the Nukeproof adapter from CReaction for converting an SLX front hub to 9mm. I'll report back as to how it works out.

    Those will work perfectly. But, you will need a 10mm thick thru-bolt axle, like DT Swiss RWS. Combined - the two make a precision reduction that is more robust than a 5mm QR, that feels no different than running full 15mm TA itself.
