Wolf Tooth MK0 ALT XC Clipless Pedals are designed for commanding performance on trails and gravel roads. These pedals are simultaneously lighter and thinner than their Shimano, Hope, and HT counterparts, with an exceptionally low stack height, while also having more platform area for control and power transfer. This body design also features a more open center for better mud clearance than other clipless bike pedals. The SPD-compatible clip-in/out experience is quick and precise, with Wolf Tooth cleats included.

The MK0 ALT XC Clipless Pedals have an adjustable Q factor in 4 mm increments. Inside the pedal is a stainless steel axle, three bearings, and two spacers. The spacers and bearings can be rearranged for Q factors of 51, 55, or 59 mm. This is simple enough for anyone to do at home. A spacer kit including four 2 mm spacers is available for purchase to further fine tune Q Factor adjustment. Like most Wolf Tooth components and accessories, replacement parts and service guides are available via Wolf Tooth Right to Repair.

Fun Glow Balls for Night Play, Great Value
Color: A) 2-Pack (2.5" Balls)
The Chew King 2 Piece Glowing Fetch Balls are a solid, budget-friendly alternative to Chuck-It glow balls. While my pups prefer the mouth feel of the Chuck-It balls, these still provide bright, visible fun for dusk or nighttime play, and can even be used indoors with a flashlight to get the game going. Durable, glowing, and engaging—a good option for evening fetch sessions which always insures that our pups get a great night of rest.

Durable, Perfect Size, and Glows
Color: A) 2-Pack (2.5" Balls)
I bought these for my 23 pound Bojack (Boston Terrier/Jack Russel) mix and he absolutely loves them. He’s an aggressive chewer that has destroyed Kong toys. This ball has just enough flex or give in it that he can’t tear it apart as it compresses in on itself. After about 6 months it started to wear down and tear a bit by the hole so I just tossed it and gave him the other one. I’ll be buying more of these as they wear out over time.

A Must for Nighttime Fetch!!
Color: A) 2-Pack (2.5" Balls)
These are an absolute Must!! We have an ESS who is nearly 2yo and destroys Every toy he has. For some reason, he doesn't try to annihilate these glow balls. If he chomps on them, it's just for a moment while he is bringing it back to you. Has just a little weight to them so it goes far enough when thrown and a nice bounce when we have to play in the house, due to weather. Wish the bright 'glow' held a little longer but stays dim for quite some time and overall, just Awesome! Also purchased the 'chuck it' brand and sent them back because these were so much better. Will be buying more, if ever needed, but haven't had to because they are So Durable.

Awesome quality glow balls
Color: I) 8-Pack (2.5" Balls)
I have bought every glow ball on amazon many times over for my german shepherds. My longest lasting balls have been the chuck-it, they seem to glow longer and not get destroyed but are expensive. These glow balls are our new favorite and not only because of the low price. They hold a good glow longer are heavy duty and fit the chuck-it thrower perfectly. I am stocking up on these. Shipping was also next day so it's 100% buy on these.

Glow in the Dark Balls
Color: 2-Pack (3" Balls)
These balls are ok, not great. The reason they didn’t receive 5 stars is because they are hard/stiff, harder to throw & heavier than the the “Chuck It” glow in the dark balls. They did not hold up to heavy chewers as well as the aforementioned balls.
