Mr Reid Excellent quality. Fitted perfectly to my bike. Enjoying the ride more now that I have the new rings.
Anthony Very easy to fit, surprisingly light for the money. Great value and looks solid!
Andy C replacement for a worn chainring
Northern Cyclist Bought a 34T to replace a worn out Tiagra 4700 inner chainring. Was not 100% convinced it would work owing to the different chain width between 10 speed Tiagra and 11 speed 105, but the internal chain width is actually the same between 10 and 11 speed, so while the cassettes are not interchangeable it seems that 10 and 11 speed chainrings are compatible. Was easy to fit (you will need a Hollowtech II crank installation tool to remove the cranks, as well as some Allen keys to attach the chainring) and has worked well since.
Mr Johnson 1st replacement ring of my 105 chainset, easy fit to return my drivetrain to new
Mr Radmanic I had to replace my existing chainring due to a stripped bolt and wear. These chainrings are great value and hard wearing
Ed Bought the 34T to replace another that had folded when a bolt fell out. Went on just fine, although you’ll need to buy chainring bolts too if you are missing any.
Mr Hopkinson Decent price and easy to fit without having to remove the cranks.
Hector JR Excellent chainring, needed to keep it as spare in case its needed in the future. It’s getting harder to find old generation rings elsewhere!
Sussex Cyclist Bought as replacements for Shimano 6800 ring. Same size and fit but cheaper. Probably weighs a couple more grams but not noticeable.
Mr Marais Quality of chainring is good.
Roy Becoming hard to find. Good price
Surrey Commuter Bought as part of a project to increase the gearing on my commuting bike to 52/36, which already had a 105 groupset fitted. That meant it was a simple job to swap chainrings and I'm now enjoying the same slick shifting & ease of putting the power down as before, now without spinning out too early.
