General information about our shipping
Smooth shifting from Shimano. The SLX may not be the best in their range however one can't complain. As good as some of the so called better gear on the market at a much better price.
Silky smooth shifting and love the ability to drop 3 gears at once quickly. Using these with the SLX brakes and the I-spec mount is very neat and space saving on the bar too.
Works with a satisfying positive click and works quickly with a suitable rear mech. Finish probably a little less smooth than XT but much lower price.
Nice and clicky, I like the thumb/index finger trigger setup up
Having fitted these with a slx shadow +rear mech the feeling is really good, nice and positive. I especially like the two way release so I can use my thumb for the down shift.
Great feel from these shifters and nice quick changes, perfect upgrade from the standard Deore's
Nice positive shift. The kit comes with cables and blanking covers so you can get rid of the pointless shift indicators. The only downside is that Shimano have gone out of their way to make the 10 spd mtb shifters incompatible with 9spd rear mechs so if you think you can do a relatively cheap upgrade to 10 spd, think again.
Having come back to shimano from SRAM with this group set, I'm very impressed, the shifting is super smooth and precise
Supplied with inner and outer cables and all end caps making the price a bargain. Precise shifting with the shadow rear mech
Great value for money, very slick shifters and easy t fit
These came with the cover plates so you can get rid of the gear indicators if you want, which was a nice surprise. Perform very well. Excellent delivery from Merlin as usual.
Why buy XT when these are as good?
Clean crisp feel & solid changes. Only buy XT if you have to watch the pounds and want a metal lever...
Fast and light!!
A great product and best price from Merlin. Good shifting all round with smooth engagement.
Better than sram X7, smooth shifting
Fantastic service and prices, not fitted yet but have rest of kit to build bike up from Merlin! Including frame :)
Great shifters at a great price , best set up i`ve used so far for slick shifting gears!
Bought these for my new build on the basis of using M666's previously. So far so good. Reliable, sturdy, really good value for money. Obviously a bit more weighty than XT's but in my opinion just as good. Couldn't find them any cheaper anywhere else on the internet other than with Merlin (and I spent a long time looking!).
Very good I'm happy
