Trail riding is all about going further, faster than ever before. The all-new One Forty 500 positively encourages you to do that thanks to an all-aluminium frame with radical new trail geometry that's equally happy cleaning the toughest climbs as it is ripping down high-mountain trails. Made for the toughest trails in the world, the One Forty 500 is the pinnacle of modern trail riding, with a super-steep 80° seat angle, low front end and bottom bracket allow it to clear the most technical climbs, while longer reach figures across all sizes and a well-balanced 65° head angle mean it’s still more than capable of ripping any descent. Fitted with a kit that delivers solid performance, the Marzocchi Z2, Air, 150mm travel fork is paired with a Rock Shox Deluxe Select+ shock. A wide range Shimano Deore M5100 1 x 11 speed drivetrain turns your effort into go and four-piston brakes turn the lightest touch into slow. Rounding off the build is a long travel internally routed dropper post.

Comfortable & well-fitting, but some differences in stiffness between batches
Size: Medium, Color: Black/Deep Blue/Deep Grey/Heather Grey
I've basically been exclusively buying these since I've discovered them. Super-comfortable and maintain their shape for a long time, but I've noticed from buying it multiple times that sometimes the pouch area has stiffer texture and more support than other times (when it's loose & stretchy like the rest of it). I wish I could specify receiving the more-supported ones because they tend to produce less....how to say, knocking the boys around.

Look great, feel great
Size: Large, Color: Black
These feel great and fit well. With most briefs I tend to the trouble either keeping the front in or not having the back cover everything but these do both things and are very soft. They also look great, even on body types not in the promo picture. They are a great set of briefs and have held up so far and I got mine a little around a year ago and wear them often.

Comfortable, but run big
Size: Small, Color: Red/Orange/Yellow/Blue
I'm a small guy and I purchased size small. The underwear are not bad. Great if you're a bigger guy or if you have a really big butt. If you're on the smaller side or skinnier though they'll fit a little loose. My butt is pretty big, but it doesn't fill out the back completely. Very comfortable though and the waist fits fine. Just a big backside. They don't ride up and so far they're durable. No fading in color and the material holds strong after many wears and washes.
