General information about our shipping
Simple and effective MTB rear mech. Best price from Merlin.
Quality product. Clearly influenced by previous XT derailieurs. Great price.
The Deore range has long been the mainstay of the Shimano MTB component line up and the current incarnation is superb, both in form and function. As long as Shimano's instructions regarding component compatibility is adhered to then once set up, shifting is precise and reliable. The finish is also excellent.
Works really well, shift is positive and the clutch does help
Really nice looking mech, great price too. Has more steel ( inner and outer cages) and weight than XT and basic jockey wheels as expected. Function wise it works a treat, no sloppy pivots or quality issues. So far so good. Shimano deore just gets better and better.
Brilliant. I use this on a recumbent with the usual two and a half chain lengths. Used to have some fairly aggressive chain slap over rough roads, not anymore, brilliant!
