Shimano Ultegra FC-R8000 11 Speed Chainrings

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!

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

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.

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!

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.

quick delivery. When my mechanic ordered the wrong one, they gave me credit for one I had to return with no restock fee!!

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.

Product as represented. Top quality Shimano hardware at Bike Tires Direct discounted pricing and fast service. What could be better!

Needed a replacement 6800 big ring after going too long between chain replacement and wearing out my old one. BTD had it in stock. I couldn't be happier with the service and price. My fav on line bike shop.

Came stock on the bike so just a maintenance purchase but really it's Shimano Ultegra, works fantastic with Di2. Original parts lasted a long time so no disappointments there. Smooth quiet and reliable.

Shimano 6800 for Shimano 6800 so worked great!

Bought a smaller ring for hill climbing on my CX bike. Easy to switch out rings when the season changes from long gravel rides to CX races.

Ultegra is a solid product in my experience.
