Review: crankset - Shipping was pretty quick less than 2 week turnaround. I upgraded from a Shimano 105 50/34 172mm arms to this Ultegra 52/36t 160 mm arms. You do have to make adjustments to your front derailleur if you go from a crank like mine to this one. You have to raise it up a little and make small adjustments. Big difference on the hills. Can feel it in the legs really good. The star plug for the left side crank arm runs a little short. I used my old one from my 105 crank arm which was like 1/2" longer than the one that comes with it. ## Features - Arm Material: Hollowtech aluminum - Arm Length: 160mm 165mm 1725mm 175mm - Chainring Sizes: 50-34t 52-36t - Bolt Circle Diameter: 110 - Bolts: 4 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BCTXJJ5M | | Additional Features | Portable | | Age Range Description | Adult | | Age range (description) | Adult | | Best Sellers Rank | #199,245 in Sporting Goods ( See Top 100 in Sporting Goods ) #904 in Bike Drivetrain Components | | Bicycle Drivetrain Type | chain drive | | Bike Type | Road Bike | | Bike type | Road Bike | | Brand | SHIMANO | | Brand Name | SHIMANO | | Color | Grey | | Colour | Grey | | Customer Reviews | 4.8 out of 5 stars 8 Reviews | | EU Spare Part Availability Duration | 1 Years | | Included Components | Crankset | | Intended Riding Terrain | Paved Roads | | Is Assembly Required | No | | Item Weight | 2.9 Pounds | | Model Number | Shimano | | Model Year | 2000 | | Number Of Speeds | 12 | | Number of speeds | 12 | | Power Source | Battery Powered | | Specific Uses For Product | Road | | Style Name | Crankset | | Suspension Type | Dual | | Suspension type | Dual | | UPC | 192790893938 | | Unit Count | 1.0 Count | ## Product Details - **Age Range (Description):** Adult - **Bike Type:** Road Bike - **Brand:** SHIMANO - **Color:** Grey - **Included Components:** Crankset - **Number of Speeds:** 12 - **Size:** 160mm, 52-36T - **Special Feature:** Portable - **Suspension Type:** Dual - **Wheel Size:** 160 Inches ## Images ![SHIMANO Ultegra FC-R8100 Crankset Grey, 160mm, 52-36T - Image 1](https://m.media-amazon.com/images/I/614+6zN5fqL.jpg) ![SHIMANO Ultegra FC-R8100 Crankset Grey, 160mm, 52-36T - Image 2](https://m.media-amazon.com/images/I/41nNtBtJXxL.jpg) ![SHIMANO Ultegra FC-R8100 Crankset Grey, 160mm, 52-36T - Image 3](https://m.media-amazon.com/images/I/61yWmlDlLHL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ crankset *by D***E on 21 June 2025* Shipping was pretty quick less than 2 week turnaround.
