A little of XC, a little trail, a lot of fun.

Your riding takes you all over the mountain, so why wear a shoe that limits you to one discipline? In the Giro Cylinder Mountain Bike Shoe you'll find versatile comfort that offers lightweight breathability for banging out miles of XC singletrack, and stiff, rugged support that has no problem blasting through rock gardens and weaving through techy tree lines. New to Giro's lineup, the Cylinder takes queues from the Privateer, utilizing a co-molded nylon and rubber outsole for superior grip that doesn’t weigh you down, and stiff responsiveness that doesn't bend under pressure.

Unlike the Privateer, the Cylinder is created with a lighter weight upper construction. It features a combination of synthetic leather and mesh, allowing for unsurpassed breathability for moisture transfer and ventilation on warm days. The toe and heel feature reinforcement to protect you from trail debris when the singletrack gets a little wild. The upper secures your foot into place with an L6 Boa system, offering 1-millimeter adjustment increments when tightening, so you can perfectly dial in your fit, and a macro-release function for easy removal. On the inside, a die-cut insole adds just the right amount of cushion to your arch and heel, keeping you comfortable during long miles in the saddle.

The co-molded nylon and rubber outsole accommodates steel toe spikes for solid grip on foot in variable conditions, if the beefy lugs aren't enough to keep you planted on the trail. While admittedly less stiff than a carbon fiber outsole, the nylon provides significant rigidity for committing power, but allows just a touch of flex where you want it when you have to hike a bike. The outsole is graced with additional guard to shield your arch from chunky rocks and fallen branches in the mid foot area, so you can stay confident when the singletrack starts to get a little hairy, and the trail ahead offers little forgiveness.

  • Lightweight trail shoe for ripping down singletrack

Bought these for my growing teenage son. He loves them, especially the BOA!

Good Shoe, Not Great

I like the fit of the Giro mountain bike shoe. I have concerns over the Boa closure system (Shimano calls it a Boa). I can never get it tight enough. It feels as if I'm going to walk right out of the shoe. I tighten it as much as I can, but then to pop it open requires some major pulling. I have had times where I really struggled getting the shoe to release. The funny part is my solution. I can easily pull the shoe off my foot and it relieves the tension on the Boa system so it releases easily. I suspect this won't last very long. I bought these as my daily commuter shoes, but I can tell that this wire ratchet system won't survive the life of the shoe. For that reason, I bought replacement buckles for my old Giro shoes where you run the nylon strap into the ratchet.

Solid show made better

Had the original privateer that fit well And had a sticky rubber sole but was too hot as it didn’t breathe well. Also over heavy use the seams gave way. This redesigned model has the same last so it fits the same and has sticky sole but with Breathable panels which breathe better. Also love the boa system which feels solid without binding and is quick and easy on the fly.


    Comfortable. Nice look. Quality build. I'd buy again.

    Great and affordable shoe

    • Familiarity: I gave it as a gift but have feedback to share

    A lot of people are hesitant at first to try clipless pedals, as getting new shoes and pedals can be expensive. With these shoes, these is no reason not to! Giro has made a really cool shoe at a great price. The fact that it features a Boa system is a huge plus as there are a number of other high end shoes that don't have anything as effective as this!
