Perfect chain for crisp shifting
My original 7901 chain lasted me 2.5 years and many miles. Wouldn't think of replacing it with anything else.
Smooth shifting, top quality product
Not sure why they make other chains when you can use these ones.
Dura Ace, Works like a dream
A very good chain at a great price. Light and silent.
Wow!!! What a difference from my previous chain? So much smoother and quieter.
Awesome chain.Very lightweight and well built, as all top shimano products. I certainly will use another Dura Ace, and another... and another...
D-A Chains are simply great. well looked after I got 5,300 km from the last one before it got to 0.75% wear (elongation). Durable by anyone standards.
Chain used on Ultegra groupset. It is quiet and shifts smoothly. It looks and feels well made. I have used a KMC quick link instead of the supplied Shimano link pin and this works fine.
Good price and good chain, hard to go past it at this price if you're replacing your chain.
Perfect match with cs-7900
Excellent chain, helps my gears shift perfectly.
It may be "just a chain" but Dura Ace makes the best hands down. Crisp, accurate shifting. Worth every dime and with Merlin's prices you'll get to save some of these dimes!
Great product. Great price. Fast shipping.
Quick reliable service item received next day as ordered
at the best price it's a pleasure to order from Merlin Cycles
Top quality chain, as you would expect from the Dura ace range of components.
Bought as a replacement for the one I already had on my bike. Very light as you would expect.
Make sure you fit it correctly to the instructions as mine had been fitted incorrectly by the supplier of my bike when I purchased it and it does have a detrimental effect on the shifting of the gears if it is the wrong way round.
I used to change my chain every 1000 miles, but have been experimenting to see what you can get out of this chain. I did 1400 miles on the last one with no wear on cogs or chainset. But I kept it clean and well oiled. For reference you do get two reinforced connecting pins supplied with the chain.
Satisfied with a smooth gear.
And very quiet.
When attaching, although the check of the back and front is required, it is not troublesome.
It will continue using from now on also.
Why pay extra for excess packaging when you can by this OEM versions
Great quality product, runs well. Lightweigh &
Well made so can't be bad.
Hard wearing and light. Good value for money
good value top end chain
Shimano. It has always been my preferred brand for their quality vs. price and aerodynamic designs.
This Chain has dual perforation on their sides, so you are able to reduce his weight to 252 grams approximately. His design is for double plate and 10 speeds.
I commend it has any cycling enthusiast. the price is quite affordable for a chain of high quality.
Thank you. to merlincycles :)
