Colin HallGood quality, especially for the price.
Mr RobertsGood product, good price. It's made my gears more responsive and smother. It's what I wanted but not very exciting!!
Philip MurrayThe wheels on the derailleur go round & round, round & round, round & round the wheels on the derailleur go round & round, all day long. Until they wear out & need replaced with these & they do the trick nicely without having to dish out on a whole new mech.
PhilWheely good. Other than make more lame jokes, what else can I say in a review about Jockey wheels? They rotate. I've never had more expensive ones with better bearings so can't compare to those.
Mr LiveseyThese jockey Wheels have been straight forward to fit and have resolved the problem of the chain jumping when traveling over the rear sprockets.
McKinnonBought to hold as spares. On offer so cheaper than the Rollerboys generic I usually buy.
BrianOEM replacements. Top quality.
DeiniolArrived promptly, straightforward to fit, and now my derailleur works much better than with the old worn jockey wheels
BIKEBUILDER2015Great value items. Helped to revive my old 5700 rear derailleur.
DeanaFitted these due to poor gear shifting and the problem was solved immediately. Check you're fitting them in the correct position and the correct way round as they have specific functions. Took about 15 minutes to fit.. Excellent service from Merlin at the cheapest price.
Veteran RiderThey made the gears shift smoothly again. Glad I bought Shimano originals
NickNever under estimate the difference new jockey wheels can make. A 4 year old bike with little maintenance, it would have been rude not to change the jockey wheels along with the chain and cassette. For such a small price, it's the difference between a jumping chain and drive chain joy. Should last a good few 1000 miles too.
SeanVery prompt delivery, best value I could find. Easy to fit and has made a real difference in the slickness of change - well overdue and worth doing.
Mr HewittGood quality, easy to fit
Mr ChampionInexpensive replacement for worn 105 derailleur. Does the job and straightforward to fit
Mr gilmoreBought to replace worn out wheels on derailleur. Easy to fit but you have to check which wheel goes in which position
neil wUsed on LX derailleur on my CX bike having reduced my old jockeys to a rather shocking state having put them through 10,000 km of mud, grit, sand and snow. Hopefully these will last as long again. Work 100% as expected, no issues.
Mr JonesGood price, Fits my 5700 105 no problem
Mr LeonardJockey wheels are an easily neglected component. These were easy to replace and just work as intended.
Mr Addison, OxfordshireThese jockey wheels fitted perfectly, as replacements for the worn out ones on my Deore LX rear derailleur. Works a treat now.
Mr Cardenas MorenoThese replaced my stock jockey wheels that were super worn down. My stock jockey wheels match this exact product and can say that the old ones lasted around 1200 to 1600 miles before I replaced them. I would recommend changing your jockey wheels about same time you replace your chain for best performance.
TimGood value and simple to replace on my existing rear mech
Mr Van DoornDerailleur and owner happy. Was going to replace whole derailleur but it works like new now anyway.
Mr FrankSimple and effective. Had a worn set of these which I used these to replace, easy to fit and restored my failing in the gears of my cycle.
Dave B105 rear mech was not shifting well after 2 years of regular use. Replaced the cables, fully cleaned the mech and fitted these new jockey wheels. Shifting now as good as new.
Mr CunninghamA nice to have replacement for a 9 year old mech. Made things quieter.
Mr BirdFitted easily enough. Works well for replacement of lost wheel. Main gripe is that bolts not included. These are easily lost if they work loose on a ride.
MattRemember these little friends if your shifting is getting sloppy no matter how much you adjust it. Ten minute job.
Mr BleaseGood value, genuine, quality jockey wheels. You can spend lots more on ceramic bearings but for value and function these are hard to beat, my previous set of the same lasted me 2years riding 100+ miles per week.
Mr staitRecently fitted to my 9 speed shimano 105 mech as original jockey wheels worn out. Drivetrain now running smooth again. Pleased I didn't need to replace whole mech.
Mr MajorThe replacement jockey wheels were easily fitted and solved a problem with gear changing that I was having. Really happy with the product and price.
Mr FoulgerSuper quick delivery and does what it says on the tin, Could have done with some instructions confirming which was the upper and lower jockey, or at least clear writing on the wheels. Easy to find online though.
scattmanThe wheels themselves are fine, however the assembly instructions could be improved, I had to go online to find my rear mech instructions to work out which way around the guide and tension wheels go, as it was the 1st time I'd changed these I took off both wheels and mixed them up before I released the 2 wheels are slightly different.
Mr Lea-CoxGreat quality. Ripped up the hills in a recent washout welsh MTB race and expected that my bike and components would take a hammering. These jockey wheels looked just like new while the rest of my bike was knackered!
Mr ChristensenGenuine product from Shimano as expected
Mr jeffsWhat can I say? They're round and they work. What more could you ask for...
Mr baxterfantastic service use merlin as much as possible
Mr CarmanWhy pay for any other jockey wheel, don't listen to the hype.
AGWhat you get is what you see. Good price, does the job. Quick delivery too.
Mr nichollsCheapest original part I could find on the web. Love Merlin Cycle!!!
Mr BillingtonVery happy with product. Obviously they don't last as long at the XT sealed bearing jockey wheels but given the price this are fantastic value!
Mr TomesGood product good price.
Mr woodDon't be fooled by other cheaper parts, shimano jockey wheels are the best replacements by miles
RMA much better alternative to replacing my entire SLX mech. Bargain!
Mr CanhamMerlin come up trumps for delivery and good prices. I feel sorry for my LBS. But as for the jockey wheels, they're jockey wheels, remove the old worn out ones and replace with new, two minutes with an allen key - simples - just get the right one in the right place.
