Chainring: (one of the) front gear(s), attached to a crank; Chainset: see Crankset; Chainstay: a pair of tubes on a bicycle frame that runs from the bottom bracket to the rear fork ends; Chain tensioner: a device to maintain proper chain tension; Chaintug: a device to aid in setting the proper chain tension
Replacement chainrings must be chosen with a bolt-hole count and spacing that matches the spider. Chainrings designed for use with multi-chainring crank arms may have ramps or pins to aid in shifting. The middle chainring, in the case of a triple crankset, usually has the most shaping to aid in shifting up and down.
There are three chainrings with half-step differences between the larger two and multi-range differences between the smaller two, e.g. chainrings 24-42-46 and cogset 12-14-16-18-21-24-28-32-36. [12] This general arrangement is suitable for touring with most gear changes being made using the rear derailleur and occasional fine tuning using the ...
Biopace is a tradename for a type of ovoid bicycle chain ring manufactured by Shimano from 1983 to 1993 [1] [2] The design was intended to help overcome the "dead zone" where the crank arms are vertical and riders have little mechanical advantage. [3] Biopace chainrings have a reduced chainring diameter coinciding with the cranks being horizontal.
Deore XT is a mountain and touring bike groupset first introduced by Shimano in 1983. [1] It was Shimano's first mountain bike groupset, based on their existing Deore touring groupset, and it consisted of a triple-, double- or single chainring crankset, front and rear derailleurs, handlebar-mounted "finger" shifters, cantilever brakes, and large-flange hubs. [1]
A larger sum requires a longer cage length. Typical cross country mountain bikes with three front chainrings will use a long cage rear derailleur. [citation needed] A road bike with only two front chainrings and close ratio sprockets can operate with either a short or long cage derailleur, but will work better with a short cage.
A great "on road" gear ratio, for the 26″ wheel, is 42:17, approximately a 2.5:1 ratio and 64.2 gear inches for versatile tour riding. Many British enthusiasts used to tour on 27–inch–wheeled lightweights on a single fixed–gear of 69 inches before multi–speed gearing became universally popular, though this certainly made for tough work.
Osymetric is a French make of ovoid bicycle chainring which has a non-circular shape whose angle is tailored to the pedal stroke of the individual cyclist. These were designed by engineer Jean-Louis Talo who claims that this improves cycling performance.
