Shimano Deore transmission

Our review

With look and feel beyond its price point, Deore is a strong contender in the budget transmission arena

Budget priced it may be, but Deore kit still packs a lot of features. With permanently attached gear displays, there’s not quite as much flexibility with shifter positioning as higher-end components, but the triggers still have the ergonomic flexibility of a two-way release.


There’s more flexibility at the front mech; with dual cable routing and Multi-fit frame shims, the decision is between high and low clamps. In common with Shimano’s higher-end kit, Deore also has a Shadow derailleur option, which is lighter, clanks less and is less vulnerable to damage than a conventional rear mech.


Shifts at both ends are accurate, although upshifts at the rear aren’t quite as snappy as Shimano’s pricer parts. Deore’s real rival, though, is SRAM’s X5, against which it scores on weight and solidity. It’s also got a distinctive look that belies its lowly cost.
