Our Box Four tier is for those people who just want less fuss! You're fond of Prime 9, but know 8 is enough, and surely 11-42T is plenty of range for an 8-speed cassette. Our derailleur still has the Limited Slip clutch but now arrives with...

Awesome groupset for a great price
I bought this to replace the hodgepodge of used parts I've been using to "upgrade" my 2013 Specialized Sirrus, the original drive train was a 3x7. My previous groupset was slipping gears like crazy no matter how much tuning I did. Slapped on this bad boy, it required almost no tuning at all and shifts like a DREAM! Given the age of the bike and my usage of it for commuting/general purpose/exercise, I didn't want to spend a ton of money on a groupset but I still wanted something that's high quality and will last me awhile. This product looks and feels well built for at least half the price (if not more!) than some other common brands. Definitely worth it!
