Shimano Ultegra FC-R8000 11 Speed Chainrings

Chainrings are Ultegra. Good quality, easy to maintain and allow for a smooth ride.

I use this product to propel my bike faster and faster until I feel like I am flying. This was a replacement to a worn out chainring I previously had on my bike. Would recommend if it is what you need for your drivetrain.

Tried cheaping out & bought a 105 series 52 for my Ultegra frontend as all my investigations' online seemed that all 3 Shimano chainrings are interchangeable (& the 105 is half the price of the Ultegra). Yes the bolts line up & the cog works as a cog, although doesn't shift quite as well. Cosmetically though Shimano rather cleverly uses slightly different colors but most importantly, the 4 spiders do not sit flush to the crank, they step down (on 105) not on the Ultegra. Looks very crappy. Bottom line, spend the extra $50 fo the correct Ultegra cog - looks right, color matches, shifting seems better. I now have a 52 tooth 105 chainring sitting around!

Having recently purchased a Trek Domane SL6 with a Shimano 11 speed 11-32 cassette I quickly realized that the front 50 tooth chainring was not giving me optimal gear ratios for the kind of cycling I was doing. Solution?

A 46 tooth Ultegra FC-R8000 chainring from BikeTiresDirect. Now I lose a top gear (which I never used anyway) and gain a mid-range gear and my spinning has improved. Great product, great price, easy to use website & great service.

there was a bit of a question as to whether it would work on a Shimano 105 and it does fit.

I swapped this out for a 36T ring because I live in a flattish area and rarely use my granny gear combo. Shifting up to the 52T outer ring is fine, and I get more useful gear ratios without spending 4x the money on a new cassette.

After alot of miles on a Crankset, the inner chainrings do wear out, thease are easy to replace.

replaced worn chain ring of the same make/model.

Got it so that I could do a fondo overseas with climbs of upnto 35%, did the job, much easier than using the 5236

I'm convinced SRAM is going 1x because they can't infringe on Shimano's awesomeness and actually make a decent front derailleur. I recently switched back to a Shimano front and love it.

Changed gearing for shimano 8000 with shimano 8000 so what can I say, they work as they should!

It was a perfect match for my Shimano 105 FC-5800.

I bought a 39T ring to replace the stock little ring on my 52T/36T crankset. I live in an area with lots rolling terrain, and the 39T ring helps me hit the gearing sweetspot without inefficient crosschaining. I run a 11T-28T cassette and never feel undergeared on hills. Shimano says the 39T is only for use with the 53T ring, but mine works fine with the 52T; I've ridden this setup almost daily for ~2 months and only dropped a chain once due to bad shifting/pedaling technique.

After 11,000 miles and a couple of chain replacements another chain was due, wearing to .75%. That was more than my original front chain rings could bear and I was slipping on my large ring after the new chain was installed. I replaced my rings with these and no more slipping. In fact, what surprised me was the decrease in noise. It was remarkable. These are not cheap but they're genuine, in stock, and shipped right away. It was well worth it.

The replacement Shimano chainring was an exact replacement for the original chainring. The great price and fast shipping made this purchase a very enjoyable experience. The first place I look for bicycle accessories, parts or equipment is Bike Tires Direct.

BTD sent me the wrong Shimano Ultegra Large Chainring for my 2017 TREK Madone 9.0 even though I requested BTD to confirm compatibility prior to ship. Post purchase, I was unable to talk to anyone thus all communication was via email. After several exchanges over several days, BTD admitted they do not have the ability to confirm compatibility in a pre purchase environment. I was told to use a Dremel tool to modify the chainring Shamino Ultegra received to "make it work". As a rider who averages 5,000 miles a year, I will never use BTD again for my cycling product needs.

Ordered this chainring to replace the exact original. It fits as expected and now my bike isn't convulsing everytime I shift. Thanks for carrying superior products.

The outer chainring is "Hollowglide" which means lightweight but pricey. Together with new cassette and chain I'm back to smooth and reliable shifting. Happy days

Easy to put on working very well. I recommend

My bike had a compact set, which was just a little too low for my fast bike. I like spinning fast on my inner ring, but with a 34 tooth Id have to almost cross chain to go my normal speed. I bought a 36, and it is perfect. Now I can keep it more in the middle of my cassette and spin away. Good quality, worked perfectly swapping the 34 to the 36, with a 50 outer.
