SRAM

Same basic review of the rear derailleur I have working with these, Force stuff works super well. I like the grip size and shape too. The bonus button is also nice and accessible even with winter gloves on, so if you ride in bad weather, this is much appreciated.

The one major complaint - holy heck Sram stop sending the levers and lines filled with fluid. We have to cut them anyway, it makes a mess, we almost always have to bleed them after running through frames, just send them dry! It'd be cool if for the time and labor savings of this you lowered the price too, I'll gladly use my own fluid and a supplied barb/crush washer. It just makes no sense to me to send them filled and bled.

And seriously with the DOT fluid in this day and age? Come on.

Otherwise, no issues functionally with the setup, works as it should, stops are awesome, no noise, they just work.

I have a Red-equipped bike to directly compare this to, and there's no differences worth talking about. You notice nothing. I care so little actually I didn't even weigh it. I do think the "better" components from the brands seem to resist corrosion more than the lower end stuff, so Force/Ultegra and up, I do seem to have less sweat rust popping up.

I really like the external batteries and how they are interchangeable, huge selling point. My only issue with Force is the front der doesn't work with big chainrings, which is sorta dumpy. I'm running 1x at the moment to make sure I like the new frame build, and will get a Red front der to handle my larger than 50t chainrings.

I actually ordered the wrong one at first, not knowing there's a standard and wide version. I've been riding my Crux on roads a lot lately with endurance tires and forgot it's a gravel bike. The team really did me a solid exchanging it for me and once I got the right one it was super quick to put on and pair with my Karoo and phone. I think someone even upgraded the shipping for me which was huge because as a result it arrived just in time for my 52mi group ride event and I could monitor my power during the ride. Very happy with it and my experience with the team!

I upgraded the standard crank on my Force D1 2x 43/30. This crank connection works reliably, and the readouts are in line with all my other power meter spiders and pedals from SRAM and Garmin. Beware that you only get the left side crank arm, so if you upgrade a D1 series like I did, you'll have a mismatched right-side crank arm, unless you also buy a separate E1 series crankset. There's also a D1 left crank arm power meter upgrade that may still be available for similar situations.
