SRAM

I really like the shape of the shifters. They fit my hands really well. The cadence jumps aren't too bad and I don't mind being on 1x as much as I thought. It's quite convenient and am now considering switching my road bike to 1x as well with this same groupset. The one finger braking is a little gimmicky. It's noticeable, but as someone that's only 170 lbs I wouldn't upgrade from the previous gen of sram or shimano to this just for that. The only knock I really have is that all the components are so expensive which you should keep in mind. The cassette is over $300 while a Shimano cassette is about half that price.

The SRAM Force E1 Thread Mount 2x Chainring Kit is an upgrade worthy of praise for SRAM. The ease of change without changing crank power meters is great. I have not seen any difference in performance of the threaded vs non threaded chain ring. I also recommend investing in the chain ring installation/removal tool for you home mechanics. It is simple and takes the errors of over-tightening out of the picture. Can beat the BTD price on the item!

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.
