Bought to replace an item on a 2001 Rift Zone which had developed slack. This was a perfect replacement, fitted easily and adjusted well. The cable did not need to be changed as the recent one was still a good length. Pleased with result and price/delivery.
Its a great derailleur which I still need for my old Marin MTB and a great price! This was the only place I could find it so thanks Merlin!!
Seems a bit bulkier and sturdier than the previous XT model I had which cracked. Shifts perfectly well.
I find front mechs frustrating but this is easy to set up
Diifficult to find a mech with capacity to work with 48-36-26, this can, and works very well, excellent value. (Used on 2 hybrid bikes both 8 speed 48-36-26)
Does what it says on the box, will deal with 26, 36 inner rings and 48 tooth large ring. Good bit of kit.
I cant really fault a shimano front mech because it is just that and they are always fit and forget items so five stars for that. I did come a cropper with this though as it did say universal fit. I have a Dialled steel hardtail that requires a 27.2 and 'universal' did not extend to that size. To give Merlin their due, the ad now states the sizes it will fit. I must stress that 'universal' appears to be a Shimano term. Refunded no issues so no worries there. You cant win every time!
As usual Shimano have produced an easy to fit, well made, front derailleur at a good price, that won't let you down.
Why spend more, works like clock work, goes on for ever, I use Deore or XT depend on deals, both are as good as your will ever need.
Needed to replace an old front mech that had become stiff and difficult to shift. This was the nearest equivalent and performs the job very well.
Removed the worn out mech from my on one. Took me 5 mins to fit and adjust my new shiny deore mech. Out for a quick spin and further slight adjustment worked like a dream. Great value and prompt delivery from Merlin yet again.
Once again another quality item from Shimano, which ensures crisp gear changes. Thank you to Merlin for such speedy service.
Reliable, cheap front mech. Does exactly what it is supposed to do.
Needed this really quick for a build and I wasnt disappointed - ordered just before 2pm on Thursday, arrived before lunch on Friday and helped me finish my bike build before the weekend Was considering XT etc but to be honest - this is just as good ... maybe a little heavier but I'm almost 15 stone and riding a steel hardtail so a few ounces makes no difference to me. Shifts perfectly every time!
Received the day after my order was placed - excellent service. And what can one say about the Deore groupset - a perfect mix of quality, strength and sensible prices - and even better value when bought from Merlin!
Works like its says on the tin. A bit bulky but good shifting.
The mech was easy to fit and working fine
Nice piece of kit. Easy to fit, cable entry point easy to use and plenty of adjustment available. Like all front mechs, a bit tedious to set up correctly. Good value for money and a quality product as you'd expect from Shimano.
Good value front mech,well made & multifit with the shims provided.Useful when swapping frames etc. Works very well out on the trails would recommend. 1st class service from Merlin fast despatch very pleased.
