Muc Off 1051 Black Tubeless Presta Valves, 44mm - Premium No Leak Bicycle Valves with Integrated Valve Core Removal Tool

I usually use 45mm stems for my wheels but needed 10mm more with these stems. This seems to be because that lock ring is thicker than the standard ring. I ended up needing the 60mm stems. The product seems pretty good and am only rating it a 4 because its about twice as expensive as it needs to be.

Edited: well, this is slightly embarrassing. Originally reviewed these negatively because one valve wouldnt hold air even after reseating the valve/replacing the tape. I went back and looked at the tape again and realized there was some kind of defect in the entire roll and there was a faint score more that was leaking air into the spokes on one side. Replaced the tape with a fresh roll and the second valve worked perfectly. TL:DR theyre a little pricey but they fit snug and the colors are nice. Lean into your vanity and just get them, theyre only like $10 more than Stans.

Nice color good product

Hands down, the worst bicycle related purchase Ive ever wasted money on. These valves are garbage! They clog if you look at them sideway and are completely overpriced. Spend half the money on Stans, WTB or some other reputable manufacturer on a better quality set of valves and ride with confidence that they wont leave you stuck on the side of the road trying to clear a clog so you can pump up your tire.

My ENVE rims were continually losing air no matter how well I tried to seal the valves. These stems and grommets are the perfect shape and durometer to make a positive seal. They even came with rim stickers and a core tool. They are worth the money.

These are great tubeless valves. Anodized metal, and even the caps are metal. They even come with a valve core remover tool that you can use as a cap. Super cool. They include multiple rubber pieces for the inside the rims to seal it, so you can choose the one that fits your hoop best.

I love that you can choose your own seal and they come with a core remover cap. No issues going tubeless on my cheap giant wheels.

Looks great. Works great.

I really wanted to keep these, but they didnt fit on my DT M1900 rims. The little rubber bungs they give you to adjust the fit wouldnt fit in properly. Overall though they are extremely well made and sturdy and look dope!

Love these stems, they seem very sturdy and seal great! Added plus, they look good on my bike. Also bought the Muc Off sealant for tubeless use, it sealed up the tire great!
