Use these end caps to convert your front Mercury hub to QR, 12mm or 15mm. Not compatible with previous hubs.
The Hub Model # must match your hubs or the end caps will not fit correctly.
HUB MODEL NUMBERS
Make sure to select the correct hub model number when ordering end caps. Model numbers can be found on the outside flange of your hub. Incorrect model number will result in end caps that do not fit correctly.
As shown in the photo to the right, your hub model number will begin with a T.
2018 year model hubs will have hub model numbers that indicate the hole count and year.

To order a replacement, you'll need to know a little about the drivetrain on your bicycle and the specific hub used on your wheel.
The Hub Model # must match your hubs or the freehub body will not fit correctly.
