Edinburgh GB Tweed Valley Play Ground
I only gave the mech an 8 for value for money as I am waiting to see how long it lasts however, if it lasts the test of time then I'd be happy to up the rating.
The mech is beautiful, the jockey's are buttery smooth, the clutch works brilliantly (better than XT) and there's a noticable weight saving. The best improvement I've noticed over XT is the spring tension, it feels much more solid and gives a lovely pronounced change although light at the shifter. Great mech!
Slightly worried I smash the Carbon cage but that should just urge me to ride better

XTR Shadow plus Dyna-Sys 10-speed rear derailleur for the ultimate in shifting performance and durability. Shimano's new Direct Mount Rear Derailleur system gives more space around the rear frame dropout resulting in easier rear wheel removal but also allows frame designers to shorten chain stays, increase axel sizes and move suspension pivots.

Key Features:
  • Direct Mount gives a simpler, cleaner look
  • Shadow plus features a super low profile design
  • Shadow Plus uses a chain stabilising switch that when on will reduce chain bounce in rough terrain maintaining more stable drive and shifting
  • Single tension spring prevents contact with the chainstay resulting in a silent ride
  • Direct cable routing prevents snagging from any trail side hazards
  • Full carbon fibre outer pulley cage saves weight while alloy inner cage increases rigidity
  • Cold forged wide alloy links and pivot body
  • Four fluorine-coated link pin bushings
  • Strong return spring for a positive shifting feel
  • Improved cable pull ratio gives a more accurate shift action
  • Dyna-Sys 10-speed compatible only
  • Durable sealed bearing pulleys for low friction
  • Top normal spring uses the spring to select higher gears
  • 35T capacity GS cage
