This Shimano 105 5600 Hollowtech II Compact Chainset is no longer available although you may find similar or newer versions below:
The new Shimano 105 Hollowtech II Chainset is lighter and more efficient than the original Hollowtech system, and makes "pro-level" technology more accessible to part time racers and fitness enthusiasts.
|Bottom Bracket Type:||Hollowtech II|
Shimano 105 is a by-product of our premier engineering range but has its own unique identity, offering a greatly enhanced and sleek design that's backed by a high performance. The Shimano 105 design concept of "smooth, Round and Natural" is consistently demonstrated in every component, giving its user a sense of satisfaction and pleasure.
The Hollowtech II crank and bottom bracket combines race-proven hollow forging technology with the integrated crankset & bottom bracket. Weight is reduced while rigidity & power transfer is radically increased.
Finished with SG-X chainrings which enable super smooth shifting. The rings use special tooth profiles, pick-up spikes and ramps to help make the front derailleur shifts quiet, easy and trouble free for you the rider.
Your chainset must fit onto your bottom bracket! There are currently four chainset/bottom bracket interfaces that you're likely to come across. If your bottom bracket is made by Shimano and it has splines, then you need an Octalink chainset. If your b/b is NOT made by Shimano and it has splines, it's almost certainly ISIS. There are a very few non-Shimano chainsets with Shimano Octalink interfaces so, to be sure, count the splines - ISIS has 9, Octalink has (surprise, surprise) 8. No matter which brand of b/b you have, if it has a square interface, it will require a traditional square taper chainset. If you have one of the new Hollowtech II systems, you will need to choose the exact chainset that matches your bottom bracket. Most MTB chainsets are now 9-speed compatible but these will work with an 8-speed system.
