Drivetrain & Brakes
SRAM 1x Eagle groupsets are best for touring on hills and bad roads. the large gearing ratios come handy when you go with extra loads and climbing hills. Not having the front shifters also make it more convenient and lesser parts (and hence more reliability). The only issue with Eagle components is not having compatible shifters which can be used on a drop handlebar and something reliable. Microshift bar end shifter has good built quality, shifts smoothly and very convenient.
These are great to have on the road for a quick broken chain fix. Or use it on a Shimano pinned chain and have a removable link on your 10-speed chain.
These come with some mountain cassettes so you can put them on a road hub. Don't forget to check your box or the listing for the cassette. Just buy one of these in case you lose it when you remove the cassette for service.
