Feedback Sports GRVL Grindr rollers? Sea Otter Classic might be late, but it’s not short on new parts from brands big and small. Here’s our first of many roundups, featuring new components and concepts.

Above are the prototype GRVL Grindr rollers from Feedback Sports, using sustainably harvested gravel that you can customize to match whatever racecourse you’re training for. They’ll help build muscle memory for the vibrations while helping you sort out proper tire selection and air pressure. But that’s not all…

They also get you ready for the fun with resistance tuned to keep you riding at a party pace while promoting mustache growth. Want one? Probably best to just start gluing things to your own rollers (don’t actually do this) as it’s not likely it’ll ever really be made. Sorry.

Adding to their Kolossos line of oversized derailleur pulleys, they have a version for Shimano 12-speed mountain bike rear derailleurs. The cage uses their stiff, CNC’d design that replaces the entire lower cage and pulley on the stock derailleur.

This one’s a final prototype that hasn’t been anodized yet, but will feature the same ceramic bearings as the ones for Eagle, GRX and road groups. The lower pulley has 18 teeth, and introduces their first narrow-wide tooth profiles for better chain management. The upper pulley has 14 teeth.

Price is $399, available by January for XT and XTR for sure, and they’re testing for SLX.

They’ve also updated their SRAM Eagle Kolossus model with a more robust lower section to improve strength, stiffness, and durability. It gets the narrow-wide tooth profile update, too, and this one’s sporting their $20 titanium bolt upgrade…

…which just so happen to also work perfectly for Pivot’s cable clamps, in case you needed something else to upgrade. Kogel offers a huge range of titanium bolt kits for bikes, check it all out at

Yoshimura Chilao mountain bike pedals

If you haven’t seen them yet, they also make these Chilao flat pedals, which use a combination of an IGUS bushing and two outboard sealed cartridge bearings, set well apart from each other for a stable ride. They get 10 pins per side, and you can choose from red, blue, black, purple, or gold pins to dress them up a bit. The front pins are angled backward slightly to ensure your foot won’t slide forward.

The shape is slightly concave, and they have a huge 110mm x 107.25mm platform, which is set close to the cranks with minimal spindle length. This keeps your feet closer in to help you wiggle through the tight spots and improve cornering clearance. Retail is $190, available now at
