DESCRIPTION
The podium-proven durable and secure trail shoe reimagined in a lighter and sleeker shape
The all-new Chamber™ III brings a new level of performance to our SPD-compatible mountain bike trail shoe. Lighter and slimmer than the previous iterations of the EWS and World Cup-winning Chamber, this shoe is ready to send it downhill but delivers plenty of power transfer when it comes time to pedal. A supple microfiber upper conforms to your foot for a locked-in feel and a new low-bulk tongue help make the Chamber III our lightest version yet. Simple, secure retention from Velcro hook-and-loop lock down strap and laces adapts to varying foot volumes, while a Giro-specific Sensor rubber outsole pairs grip and durability. At the heart of the shoe, the clipless-compatible DH plate with +10mm optimized cleat setback strikes the perfect balance of stiffness and walkability. Deliver secure, durable power to your pedals with Chamber III.

Note: Make sure the helmet fits with a little room when the fit system is loose, and sits low enough to protect your forehead without hindering your vision. Once you’ve got the right size, you can adjust the fit.

MEASURING YOUR HAND FOR THE BEST FIT
You can measure the length and width of your hand as illustrated above, and use the Size Guide to determine your size.
1. Wrap the tape measure around your hand at the widest part of the palm, and lightly close your hand to get your Hand Width measurement.
2. Once you have that measurement recorded, use a tape measure to determine the length of your hand from the tip of your longest finger to the base of your palm at the wrist. This is your Hand Length measurement.
3. You can then compare the measurements of your hand with the data supplied in the Size Guide to determine the best fitting size for you.
