Top Features of the Shimano Tiagra 4650 Hollowtech II 10 Spd Compact Chainset
- 2-piece cap-free design is quick and easy to install whilst being lighter and stiffer than a traditional crank/ bottom bracket assembly
- Designed to work with HollowTech II type bottom bracket cups
- Compatible with 10-speed Super Narrow HG chains
- Anodized aluminium crank arms
- Lightweight aluminium chainrings
- 110mm bolt circle diameter
|Bottom Bracket Type:||Hollowtech II|
Fitted with SG-X chainrings, these feature strategically placed chain pick-up pins and tooth profiles to ensure fast and positive shifting.
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.

Product Q & A
Ask your questions and share your answers.
Tiagra is now 10 speed.
will the 10 speed cassette fit?
Will a hollowtech bb fit where my square taper sits at present?
Will I need new gear levers to use all 10 gears?
What about front and rear mechs compatibility?
That lost will cost a fortune.
Will a new bike be cheaper?
Is there a compatible 9 speed system?
This 10 speed chainset works well with my 8 speed chain, so shoupd work with your 9 speed. As long as you're replacing a double/ compact, you won't need to change your shifters.
As with any new chainset, you'll probably have to adjust the front mech's travel limits etc, but that's it.
The front shifter will if its a double but the rear wont as it is 8 speed
I used the Shimao Tiagra 4600 Bottom bracket.
I also used 105 Stis on this setup.
best of luck
