The Specialized Foundation Bib Knickers offer all-day comfort with added coverage for cooler rides. Made with the same breathable fabrics and trims as the Foundation Bib Shorts, they feature a 3/4 length to keep your knees warm in chilly conditions. Plush elastic suspenders and a lightweight back panel enhance breathability, while an elasticated cuff with silicone gripper ensures a secure fit. The Single Density Body Geometry 3D Chamois delivers lasting comfort, and with 80% recycled nylon, they provide sustainable performance without compromise.
The low compression fit of our Specialized Foundation Bib Knickers is more forgiving than our other fits, making it more comfortable for more body types—striking the perfect balance of supportive yet not overly restrictive.
Stretchy elastic suspenders are plush and soft against the skin.
Lightweight back panel supports bib straps and aids temperature control.
Elasticated cuff with silicone gripper provides a gentle, secure hold on the legs.
3/4 length provides additional knee coverage in cooler conditions.

Everything was great. Was waiting for the SL9 to release since the first leak. Going from a SL7 was night and day.
Also Sierra Bicycle Supply, was amazing. Will be shopping here plenty more. The service they displayed was top tier, from the order placing online all the way to the delivery.
After many years I wore out my derailleur gears. Since I ride on my wind trainer daily, I needed to get up and riding again. Riding us part of my cancer therapy. Replacing the gears was a quick and easy way to fix the problem. Cost was fine and the delivery was fast. Thank you.
Got this for my kids bike. He does XC racing. Has been riding in dry lose dirt, wet conditions. Lots of climbing and some downhill. He loves them. Shipped fast and in sexure packaging. I would definitely buy again.
Heard a lot of good things about this tires put them on my commuter. The roll much faster than the schwable energizers on it. Puncture protection only time will tell.

Literally EPIC
Fast shipping and perfect frame set as described. It's literally the lightest built MTB I've ever felt. My wife will be smashing on it at this year at the Leadville 100. LFG Thanks guys!

Exceptional Wheels
The CLX III are exceptional I was a little apprehensive about buying them having ridden the Enve 4.5 but you feel less crosswinds and their lighter and spin fast. The spokes seemed to offer a lot of dampening vibration. Win win in my book.
