Necessity for SRAM AXS road flattop chains. Stock up on a bunch especially if you need to take your chain on/off frequently (like for waxing). Not 100% sure on the one-time use aspect, but better to be safe than to risk damaging your drivetrain.
Really make sure to line up the notches and make sure it's securely locked. I've had times where I line up the notch on the front, but the notch looked "OK" in the back. Nope! That resulted in a snapped power lock
IMO best looking rotor on the market, also very reliable and works great in mixed conditions. The edge of the rotor is polished so wont cut your hands/skin. And the rotor is very sturdy, wont warp as easily as the Shimano ICETECH Steel/aluminum/steel sandwiched rotors. Cheaper than Shimano/SRAM rotors. Great value. Not the lightest rotors on the market, but it's only 20g of difference, 2 rotors is 40 ish grams. Equiped all my bikes to these rotors.
This tire is fast, durable, puncture-resistant, supple, and sticky. I run a size 35c, so my only minor criticism is that it has some weight. I haven't used this particular version in smaller sizes, but I come from the time of running 23c GP3000 tires that were the best you could do at the time. They weighed much less, and I got flats all the time, and slid out on wet corners, and 120psi rattled my elbows. I run these tubeless and have been getting about 5000 miles out of a tire, without needing to repair any flats. I get curious about other tires, but I always just come back to these as they haven't let me down over 15K miles.
Can't really say a lot about these that would skew anyone's decision. They are fast and grippy, it seems almost every wheel profile is designed around a GP series tire, it's a solid choice.
They are way too expensive for a tire. For a bicycle. For a race tire they won't last long for sure, so you're paying for speed. Even on sale they are expensive. No one forced me to buy them but just from a practical standpoint, they cost too much.
