What Year is Dura-Ace 7800?

Dura-Ace 7800 is a Shimano road bicycle groupset that was released in 2005. It was the successor to Dura-Ace 7700 and was superseded by Dura-Ace 7900 in 2009. Dura-Ace 7800 consisted of a crankset, bottom bracket, cassette, chain, front and rear derailleurs, STI levers (shifters), and hubs.

The crankset was available in three chainring configurations: 53/39t, 52/39t, and 50/34t. The bottom bracket used cartridge bearings press-fit into the frame. The cassette sprockets were made of titanium and ranged from 11-25t to 11-28t; an optional 12–23t cassette was also available for use with the 50/34t chainrings.

The Dura-Ace 7801 chainset featured hollow-forged crankarms and an integrated axle design similar to that used on Dura-Ace 7900. The front derailleur had a capacity of 14 teeth while the rear derailleur could handle up to 28 teeth difference between the largest and smallest sprockets (an increase of 2 teeth over its predecessor). The STI levers incorporated carbon fiber into their construction and added an extra set of stop screws to prevent accidental shifting into the innermost ring on triple setups; they were also slightly longer than previous versions to improve ergonomics.

The hubs were made of aluminum with steel axles and featured adjustable cup & cone bearings; quick-release skewers were included as standard equipment. Disc brakes were incompatible with this groupset due to clearance issues with the STI levers. Dura Ace 7800 proved popular with professional cyclists due in part to its low weight – it weighed just under 2000 grams for a complete group when equipped with titanium sprockets – and its reliability and smooth shifting performance.

Bottom Bracket

A bottom bracket is the part of a bicycle frame where the crankset is mounted. It serves as a housing for the bearings that allow the crankset to rotate freely. The bottom bracket itself is usually made of metal and houses either ball bearings or cartridge bearings.

Ball bearings are held in place by cups that are threaded into the frame, while cartridge bearings are held in place by an internal housing. The bottom bracket shell is the part of the frame into which the bottom bracket is inserted. It is usually made of aluminum or steel and has threads on its inside surface that mate with those on the bottom bracket cups (if using ball bearings) or housing (if using cartridge bearings).

The width of the bottom bracket shell influences what size crankset can be used with a given frame. For instance, many road frames have a 68 mm wide shell while mountain frames have a 73 mm wide shell. Some newer designs use even wider shells to accommodate larger axles and bearings as well as to stiffen up the area around this key structural component.

There are two basic types of bottom brackets: threaded and press-fit. Threaded bottom brackets screw into threads cut into the inside of the bottom bracket shell. They include an inner sleeve over which the right-hand cup screws in clockwise while the left-hand cup screws onto it counterclockwise, or they may thread directly onto one side with external lockring threading onto them from the other side after both cups have been installed(this latter system — known as Englishthreading — requires special tools).

Cups may be flush with the outside face of the rear dropout when installed or they may protrude slightly so an adjustable cone wrench can get at them more easilyto make adjustments.
