SRAM

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

Great looking cassette! looking for an upgrade from the larger and heavier "mullet" set up I was running. I didn't want to go full on road gearing due to the fact that I ran a mullet set up for racing gravel. I looked at logical upgrades for my Rival drivetrain and this cassette came highly recommended! I can make changes to my chainring side and feel confident that this 10T-44T cassette will still provide enough variations in gearing to help me up steeper efforts out on the gravel!

Pairs right up and works without a hitch so far, hasn't dropped connection and does everything I'd want it to. One time before a ride I had to de-pair and pair again after it wouldn't connect, but that was just a weird one-off thing seemingly.

The reason I took off a star is because the unit I received was very obviously a used and returned open box with a bunch of grease everywhere, but I figured as long as it worked it was no harm no foul even though it was supposed to be new.

I have SRAM Force on my Trek Emonda. I decided to upgrade my front derailleur from D1 to E1 (skipping D2) because I was having issues with clearance between the inside of my drive side crankarm and the outside of the derailleur cage while in the big chainring. Setup on the E1 was straightforward with the included alignment tool. As advertised, the cage is narrower. Another noticeable change from D1 is that the bolt for the back of the derailleur cage moved from outboard to inboard. The end result is that there is now AMPLE clearance between the derailleur cage and the crankarm! Quiet and smooth shifting. Only minor gripe is that BTD doesn't mention that a battery is not included (although they disclose that on the Red derailleur). Definitely a pricey upgrade for just a front derailleur, but for me, well worth it!
