Mr BrownReally happy with item I bought and delivered really quickly. A great service and will keep using Merlin! :)
MarcosBought to replace (and slightly upgrade) old cassette that had teeth worn down to the gums!. Next day delivery, super easy to fit and the bike feels brand new!!. Shifting is the smoothest its ever been :)
JordanVery good quality and shifting gears feels smooth.
Gustoideal, replaced my xt7100 with this, same ratio, works a treat as the old one wore out... covered another 150 rough terrain no issues so far....well happy
DanUsed shimano xt/xtr all my life,has never let me down.
P HallettVery happy with the range on this cassette, it shifts very smoothly too.
Revolution Training & RepairI love XT products. You can feel the quality out of the box. Lightweight and very easy to fit, the components involved in the 1x12 shift crisp and smooth. Just remember XT uses a microspline free hub body.
JanLove the ratios, much more even spread of low gears compared to Eagle. Shame it requires another free hub body but micro spline is neat and so far more robust than older alloy Shimano hubs
Mr ConelyWhen coupled with a full Shimano 12 speed drivetrain, this thing is great! Just keep in mind, you will need SHIMANO 12 speed compatible derailleur, shifter, chain and chainring, and indexing is NOT the same as SRAM 12 speed. Also note that chain length determination for Shimano 12 speed is slightly differnt (longer) than past drivertrains! Get is wrong and you're shifting will NOT be ideal!
Mr O'CallaghanMy bike came with another cassette on it which never shifted right. I put this Shimano cassette on my bike and the difference is incredible, the shifting is perfect and runs silently
StephenRuns so smooth but yet to put miles on it.
