A solid training partner.

The days of clear delineations between delicate race wheels and bombproof training wheels are largely past, but it still feels wrong to head out the door into a looming weather forecast and risk putting our beautiful carbon wheels through the stress of high winds, rainstorms, and the road grime that often accompanies those conditions. Instead, leave the carbon at home for more fair weather endeavors and swap out your brake pads to roll under the clouds with calm peace of mind on a solid set of aluminum training wheels like the Mercury Wheels M1 Clincher Wheelset.

Made from lightweight yet durable alloy, this wheelset is the ideal training companion to give your race wheels a break from the elements and a more than capable option to have waiting patiently in the wheel pit or follow truck on race day. A 17mm rim width sits on the narrow side of ever-widening rim trends, which we feel makes this wheelset well suited for riders who prefer 23mm or 25mm road tires over something beefier.

  • A reliable aluminum road wheelset
  • Alloy rim construction balances strength, weight, and cost
  • Shallow rim depth remains stable in the wind
  • Aluminum braking surface provides stopping power in variable conditions
  • Internal rim width promotes ideal road tire shape
  • Laser etched logos won't peel away

Great wheels!

  • Familiarity: I've used it several times

I have these M1's on my Trek for training wheels. Great quality and price! Highly recommend!

Nice wheels!

  • Familiarity: I've put it through the wringer

I use these as my main training wheels with Conti tires mounted on them. Have over 1800 miles with no issues. Great quality and price!

Unanswered Question

are these the tubeless compatible version as currently listed on the Mercury website? And as Jen C. asked below, what is the true weight without or without skewers?

Unanswered Question

Why are the weights listed different on different websites for this same exact wheelset? Here says 1690g, Nashbar 1500g and Mercury's own site says 1580g. Which one of these is a false weight? You think the manufacturer site would be the most accurate?? Are these on sale everywhere due to quality issues? 1500g might be ok to me if pretty good all around wheels, but closer to 1700g isn't.

Placed them on my Giant for some training wheels and can't think of a better set to roll 1000's of miles. Riding with 25mm tires makes for a perfect combo, especially on rides longer than 50 miles.

Everything at first glance looks great but three broken spokes in less than 1000 miles is a problem. There is a build quality issue that is inexcusable. As a 145-150lbs rider there is no reason for this kind of issue.

Michael, Have you reached out to warranty or support?

I have these as well and am in the 135lb range and have had to have them trued and spoke grab used on them 8 times in less than a year. I would avoid at all costs.
