Shimano Ultegra 6701 Chain - 10 Speed
  • Super narrow lightweight 10-speed directional chain for optimum cassette and chainset interaction and maximum power transfer
  • Chain uses a directional design with specifically shaped inner and outer plates to optimise shifting over the chainset and cassette
  • Outer plate design has been developed to reduce the chance of chain suck
  • The inner plate has been developed for better contact with gears providing smoother shifting under high load, giving efficient pedalling, increased rigidity and near silent running
  • 5.88 mm chain width, optimised for 10-speed
  • Super Narrow HG drivetrains
  • Weight 267 grams


Mr BixleyGood chain, nice shifting.
MarkGood quality 10 speed chain.
Aaron FillionNo issues, works as it should. I find shimano chains ride smoother that other chains.
IgorThe best 10s chain that shimano ever made! There's no other chain than this one, just hit the "buy now" and be happy.
Mr BovingdonAlways used Sram for the ease of Powerlink but tried Ultegra for something different and is just as good.
Mr RutaDuraAce chain does not seem to be available so I use this chain on all better 10 speed set-ups. Good shifting (if installed in the right direction), long life. May be a bit noisy at first with some gears, but quiets down with use.
Mr ElstobExcellent chain for all-round performance and value. I upgraded from a lower-level Shimano chain, not sure exactly which one, but this Ultegra version seems to shift slightly better. It might be just perceived smoothness, but regardless it definitely seems better than before.
Mr BerkaExactly what you would expect from high quality chain. Pretty quiet, last long. Not much more to say about it, really. It does its job well.
Mr HewittReally good quality chain, should last for miles.
Mr HarveyShimano chains are always super smooth, quiet and great quality.
DeneSolid and reliable. Not that I recommend failing to maintain your chain, but, if you tend to neglect it this one seems to last longer than other brands
TurboAs always chain performs exactly as expected, at a great price.
AndrewDShimano chains are still my go to. They perform well and are better priced than many of their competitors. My regular rides along coastal bikeways takes it toll on chains (salt and sand grit) so regular replacement ensures the whole system continues to operate effectively. This is a top shelf product at a reasonable price meaning maintenance is affordable
AnacondaQuiet operation and smooth shifting
Mr JohnsonGreat chain, never use anything else. Great service from Merlin as always.
Mr ZanieckiGreat chain, it is Shimano so, no issues
MartinGood durability for road and mtb
DavidGreat product, I would not put anything less on my bike. With the Ultegra cassette and derailleurs I have problem free shifting.
Mr DegraffGreat lightweight chain, have used shimano products for years and know they are reliable and long lasting, and can take a lot of bad weather, dirt and grime and still work without any loss of traction.
TheronReplacement for an identical chain - worth the cash to replace regularly.
Mr Fat_TailMy favourite 10 speed chain. I usually get around 4000 km out of each chain. Keep it clean and well lubed.
M JacksonI'm using this on my 1x10 mountain bike and it's shifting as well as any other Shimano chain I've used (XTR and XT).
Mr HwangOnly marginally heavier than Dura Ace, but works just as well
Mr schilpI have used these chains for many years and find them to work well. I ride hard at a low cadence so am very hard on chains. These typically last me about 2,000 miles so are about the best value dollar per mile.
McCrearyVery durable quite chain. GREAT improvement to my drivetrain! Shifts very well!
FullerDoes the job and shifts nicely (comes with one pin) - make sure you put on the right way as it is directional.
Mr WilliamsVery good quality, light weight, easy change of gears when fitted
Super CommuterTypical robust Shimano product, have been using this model chain for tens of thousands of kilometres and never had a failure. Merlin had the cheapest price at the time of purchasing of all the major online retailers and the free delivery to Australia meant I paid around half of what it would cost to buy locally from a store.
ArslanMust buy product for sets to the shimano 105. I am using tiagra set but pedaling and shifting performance was changed dramatically. It bends and flexes incredibly nice and doesn't make any problems.
Mr MacLeodGood solid workhorse chain.
Mr ChapmanA light chain that shifts well.
Mr BinghamAlways a good chain to buy, find nothing wrong with them
Mr GonçalvesVery good chain. Recommended
Mr WilcoxGreat chain, runs very quietly!
Mr EdmondsSmooth as butter. Excellent chain and value.
Mr BrooksOnly a chain but you won't get far without a reliable one! I have always found the upper range of Shimano chains 100% reliable and with care, very long lasting.
Mr BoltI appreciate the design of this chain - it's specifically engineered for incredibly smooth shifting and light weight.
Mr AyearsFantastic value from Merlin. Great chain quick, smooth gear change, why spend more on Dura Ace?
NialThe ultegra chain gives smooth changing and the service from Merlin is excellent as normal
fritznessQuiet, perfect shifting.
Mr GilLooks resistant to corrosion and overall better quality than the 105 chain. When paired to the Ultegra cassette seems a bit smooother. Cannot speak about durability yet.
Mr DownieA smooth, well engineered chain.
Mr HawkinsI am now on my fourth Ultegra chain and cassette combination and they have performed flawlessly. There is no real difference to dura ace other than the weight saving for me so save your cash !! One massive difference I have found is that I replaced the Jagwire cabling on my bike with the Shimano PTFE kit and WOW ! It's transformed my Ultegra set up. The shifting is ultra smooth. When changing up or down it's a slight push to the click and it's changed. No more push and hold or push and push a touch more then oops it's a double click like with the Jagwire cabling. I never realised how good Ultegra really is until I switched to PTFE. Oh and thanks Merlin for your as usual excellent prices and delivery times !!
Mr BertholdiExcellent product, long life, good performance..
Mr AdamsRuns smoothly and near silently. Definate improvement on the previous Tiagra chain,
Mr GinnGreat value chain from a trusted brand that lasts for ages with an occasional clean and lube.
Miss PinionGreat chain, great Ultegra quality
JMDSmooth running and quiet, as to be expected from Shimano.
DeanFitted this to my Sram Red group set, replacing a Sram Force chain which was not worn just very noisy. It sounds much quieter now. I do find Shimano chains to be the smoothest and quietest. Plus at Merlin's price it is a real bargin.
Mr OdiniusNice and smooth using quick link as well
Mr WelchVery easy to install as shimano supply a special pin which you can slot in place with your fingers and away you go. I only wish they would include a powerlink like some other brands so that you don't have to use a chain extractor tool to remove the chain. A minor niggle as it's not something you would need to do very often. In terms of longevity or performance only time will tell.
Mr siggeeThis chain was simple too fit and comes with one chain pin. Fits nicely and runs very smooth. Tested this out on a 75 mile ride and a 50 mile ride so far and it certainly glides nicely. Running this chain on a sram force crankset and ultegra fd, rd and cassette. Great price at present on Merlin and well worth a go. Not much price difference between 105 chain and this one however weight saving and performance i believe are noticeable.
Mr FeltonExcellent well made and reliable chain, Quiet and smooth shifts, I always use the KMC quick link as the Shimano pin is a Faff and it makes taking the chain off much easier. Make sure that you put this chain on the right way as its directional. As always top service from Merlin, great price and rapid delivery.
MattThis is a great chain and an incredible price! Haven't had an issue with shifting and never had one of these break. (provided its kept well greased)
Dr BeckettI've got through loads of these and keep coming back for more. It does what it's supposed to and I've not had one snap on me for well over ten years. I've also ridden them with three joining pins, due to a number of frame swaps, with no problems. I'm very happy with this product.
Mr BertholdiExcellent product...
Mr HydeA high-quality chain at a fair price, with Merlin's usual rapid service.
Mr HeynsExcellent chain at a brilliant price, many thanks
Mr HouriganQuality shimano chain, not Dura Ace but whos checking?
Mr WalkerBrilliant chain - runs as smooth as silk even on a 2006 version of the Ultegra groupset. Great price too.
Mr endoI upgrade from 9-speed to 10-speed, changing the triple crank to double one. That causes me to change everything. I must have spent more money, but here "Merlin" gave me good prices. Thanks so much, Merlin!! Next time again I will definitely come and buy some, I swear. I was lucky I found this nice internet shopping. Thanks.
Mr StittGreat shifting chain and pretty light. Wouldn't use any other with my Ultegra groupset. Just remember it's directional and has to be put on the right way around!
Mr MANDYGreat chain. Essential for your bike maintenance. Great price and ultra swift service.
Mr BrownGood quality chain - always use Ultegra chains and never had any bother. Last one saw me through all the filth and grime of the 2012 english summer and still cleaned up well after each ride. I generally change them after about 1500 miles, by which point my chain checker is starting to indicate enough wear to warrant the change. With Merlin's discounted price, it's a lot more affordable to change them!
Dr KesselGreat chain at a reasonable price. Works especially well with Shimano drive train.
RattyUltegra is a solid option at the price point. This does the job and has never failed on me in five years.
Mr SpeckExcellent piece of kit at an excellent price.
Mr TajimaAs always excellent service an delivery and a great buy
Mr newbyGreat quality as described ..Excellent competative prices. the postage is always the fastest online... CUSTOMER SERVICE IS AS GOOD AS IT GETS
Mr HouriganQuality Shimano product at a very very good price. Will be ordering more soon!!
Mr nolanQuiet slick shifting from a chain so light yet so strong
Mr HarrisGood and light chain
Mr BaxterShimano Ultegra first class components will purchase every time, 5 star.
Mr KearneyBest price going around. Swift delivery also. Cannot fault Merlin
Mr DrysdaleShifts well, light, no problems so far. Can't fault the chain. Merlin's service was, as usual, incredibly fast. Overall, very happy!
Mr PickettFound prices were competative on my 5 purchased items, the postage delivery was on time and well packaged. No discount was received on postage ? I will be a return customer if prices and delivery costa are faverable cheers Garry
Mr GoreNo packaging other than plastic wrap, which honestly doesn't matter, but a great deal on the chain!
Mr BowersBought this chain to use with a new Ultegra cassette. My original chain and cassette were Shimano 105 5700. To be honest I don't notice any different in shifting performance. Shimano gear shifts are very good across the range of groups anyway.
Mr nolanI replaced my tired and stretched 105 when you get to hold both of them at the same time you can feel the weight difference .The ultegra looks like a quality product
Mr ZaharioudakisVery solid and silent chain, very pleased with it.
Mr Dawson
