Cannondale became a leader in bicycle innovation in the 1980s with the development of their lightweight yet strong aluminium frames. During the 1990s Cannondale further solidified their role as an industry leader with their groundbreaking suspension technologies. The Delta V was introduced at the dawn of the 1990s, but it was the Super V model that proved a full-suspension bicycle could be compete with the best bikes on the market. The Jekyll model of the 2000s carried on Cannondale's legacy as a top-shelf bike manufacturer.
The backbone of this mountain bike is Cannondale's aluminium Jekyll frame. This frame employs a single pivot design that provides for more rigidity for increased pedalling efficiency and handling prowess than designs built around multiple pivot points and linkages. The mainframe and swing arm of this Cannondale are both built out of aluminium alloy and are linked by a Fox Float air shock providing 4.5 inches of suspension travel at the rear wheel.
The Jekyll 700 comes equipped with Cannondale's HeadShok Fatty DL suspensions fork. This fork is an air-oil design equipped with a switch to turn off the suspension for long hill climbs. The Fatty DL provides 3.2 inches of suspension travel. This fork moves on a set of 88 needle bearings which creates less friction than the standard bushing design, allowing for more responsive tracking over stutter bumps. The Fatty DL equipped on the Jekyll 700 is disc brake specific and does not include mounts for traditional V-bakes.
Cannondale's Jekyll 700 full-suspension bike offers 27 speeds with most of its shifting equipment being furnished by Shimano. Mounted onto the rear wheel is a 9-speed cogset with gears ranging in size from 11 teeth to 34 teeth. This bike is outfitted with a Cannondale PX3 crankset mounted to a Shimano STX bottom bracket. This crankset comes equipped with a 22-tooth climbing gear and a 32-tooth middle ring, while this gear's big ring has 44 teeth for top speed pedalling. A Shimano XT derailleur handles shifting duties for the rear gears, while a Shimano LX front derailleur handles shifting for the front gears.
The Jekyll is outfitted with Cannondale-branded T-6061 aluminium alloy handlebars mounted to a Headshok Si stem and headset. Mounted on these handles bars are a set of Shimano Deore shifters and Magura Julie brake levers that are connected to a set of Magura Julie disc brakes.
The 2001 model year Jekyll 700 was equipped with a 32-spoke Cannondale Expert Disc wheelset, while the 2002 model came from the factory with a set of 32-spoke Mavic X223 rims laced to Shimano hubs.
