Click the image to buy the whole set. But it is only on the right. We should leave clear information so that customers can choose one set. Do you want to buy one from the left side? Took 1 more time to ship to the left. It is invisible to see if our shop has some information input to make customer confuse.

Can now pedal fast through corners

Duraace quality with ultegra prices. I have had (mostly) ultegra on my bike, with a few crucial duraace components thrown in. When I needed a new chainset with shorter cranks, didn't hesitate to go for the ultegra variant again, lot better value and does as good a job.

Exactly as expected

Bought a new Ultegra chainset which, was recommended after a bike fit. Collect in store was very quick and everything was exactly as expected. The staff at the Oakham store are very helpful & approachable. I could also use my Defence Discount Card so got an extra 10% off.

Game changer

I have always been riding with 170mm, pretty much the only option in town. But the 160mm changed everything. Faster cadence, hip tightness is gone, overall more efficient and more comfortable. Highly recommended.

Going Shorter!

I bought this 160 mm crankset to replace my 170 mm, 11 speed cranks. Although Shimano don’t recommend using the 12 speed crankset with 11 speed set ups, it works as well if not better. If you need a wider range of crank lengths, this is a serious option for Shimano users.

Great customer service from REI, not warehouse.

The product itself is excellent, but warehouse quality control really dropped the ball. I was quite disappointed when the crankset arrived used (dirt and scratches from prior use) with mismatched R8000 cranks, not 8100. Telephone customer service was excellent and is shipping me a replacement.

Power happy!

Bought this a month ago having hummed and ahhd about it for ages. Being non-mechanical had the bike shop fit it (£30) but very easy to pair with garmin. Looking at instantaneous power as your climbing validates your effort somehow and even on the flat values can be related to FTP so you know how hard you’re working. Probably wouldn’t have bothered at full price but at more than 50% off couldn’t resist

Reliable Cranks

I bought these cranks as backups for when I travel. Most frames my size come with 172.5 mm cranks; however, I ride 170 mm cranks. These are affordable, reliable, and never disappoint.Highly recommend.

Shimano Ultegra R8100 Hollowtech II Crankset 50-34T 170mm

The comments from my initial review are still equally valid several hundred kms down the road. Great pricing, excellent service. Very happy.

Shimano is always great

Great value over DA. Ultegra is overall best value over other groupsets.
