We love the sharp, corrective shifting of Shimano's Di2 groups, but all that tech goes to waste without a power source. Enter the SM-BTC1 Di2 Bottle Cage Battery Mount -- or rather, insert a BTR-2 battery into this thing and let the shift levers fly. The SM-BTC1 mounts on your frame's water...

A misaligned hanger will hamper shifting no matter how much cable tension and limit-screw magic is applied during a tune. Keep the Storck Mountain Derailleur Hanger around so you're ready to replace a bent one and ensure proper shifting when it's needed.
Surly Single-Speed Kit
Convert your freehub cassette body into a one-geared evil ruler with the Surly Single-Speed Kit. Just remove your old cassette, slide on spacers, cog, and lockring, and now you can look pain in the eye and laugh maniacally whenever you get on your bike.
