To determine what model you have, look on the back side of the cage. If it's not stamped there, it is somewhere else on the derailleur. If not, and assuming the entire group is the same vintage, you can find the number on say, the back side of the rear derailleur parallelogram.
How do I know which Ultegra?
Shimano cranks are all identified with model information above or surrounding the area on the backside of the pedal threads. For example; FC-6700/6750 = Shimano Ultegra. The crank length is often located in the same area, which is helpful to note before placing an order.

Shimano boasts that, “At its lightest set up (Di2 with mechanical braking) Ultegra R8000 weighs 4,071g, which is an 84.5g saving over Ultegra 6800.” Okay, but that 84.5g saving includes wheels and pedals, and many people will already have favourite wheels and pedals.

Worthy of note: the new R8000 components are all cross-compatible with the previous 6800 generation and just about any other Shimano 11-speed mechanical groupset. This means that if you're on a recent 11-speed Shimano road groupset, you can mix and match many of the components reviewed here.

How do you measure a front derailleur?
1) Clamp Diameter or Interface
“Clamp-On” front derailleurs come with a clamp of a specific diameter, which are meant to fit around different kinds of bicycle frames. Most frames will be either 28.6mm, 31.8mm or 34.9mm in diameter, but certain bikes made before the 1980s will have a slightly smaller tube diameter.
Where is the serial number on Shimano?

What is SS and GS?
It's easy to remember that SS (short cage) is for cross-ratio road sprockets and GS (medium cage) is for wide-ratio sprockets, but just because the maximum number of teeth is large doesn't mean that GS (medium cage) is the best choice.
What is SS in rear derailleur?
Shimano categorizes its rear derailleurs into three tiers depending on the cage length, and they're denoted by the suffix on the model number. “-SS” refers to the short-cage versions, with a maximum chain capacity of 33T or less. These are usually the domain of road bikes.
Are Ultegra chainrings interchangeable?
Yes you can get a 52/36 to fit compact cranks. In fact the 36 won't fit on a standard chainset. A standard crankset is typically 130 BCD and a compact is 110 BCD so they're certainly not all the same. 5800/6800/9000 are all the same – they've got the assymetric 4-bolt pattern for this reason exactly.
Is ultegra R8000 Di2?
The new Ultegra R8000 series is taking our rider-tuned philosophy to the next level, with an extensive range of components for mechanical shifting, electronic shifting (Di2) and time trial / triathlon.
Is Shimano Ultegra R8000 electronic?
Shimano Ultegra R8000 Review. Shimano Ultegra R8000 is the company's second-tier drop-bar drivetrain. Under the Ultegra umbrella, there are two shifting methods (mechanical and electronic) and two braking systems (cable actuated and hydraulic disc)–as well as bits for triathlon and time-trial bikes.
Is Ultegra R8000 good?
Ultegra R8000 verdict
Ultegra R8000 is best seen as an overall refresh of the venerable Ultegra 6800 groupset rather than a drastically new design — lots of small refinements make the groupset an absolute joy to use with braking and shifting that is largely indistinguishable in performance from Dura-Ace 9100.
