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.

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.

After searching all over for a 165mm Ultegra crank, I stumbled across Cambria Bike. Having never heard of them before (being on the East Coast), I called them up to confirm what I was seeing their site, to what was actually in their inventory. The staff was knowledgeable and helpful, they assured me that if it says "available" online then its in stock. I placed my order and within 8 hours my part shipped.. I was riding 3 days later! Excellent service and great customer support! Ill be buying again from Cambria

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.
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.
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.
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
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.
The comments from my initial review are still equally valid several hundred kms down the road. Great pricing, excellent service. Very happy.
Great value over DA. Ultegra is overall best value over other groupsets.
