Width between outer and middle
12 Jul 2017
Hi what's the horizontal width (as you look down from the top tube to the ground) between the outer and middle chainrings as i want to use the rings for a sora crank (which is a triple)

The space between the two chainrings is 5mm.

Hi, this chainset has alloy crank arms & steel chainrings.

More Information Please

Please could you tell me what speed 8,9,10 or 11 speed will this work with ?
I am presuming this is for square taper bottom bracket ? Does it matter which type of square taper ? I have a British 1997 Raleigh racer, originally 7 speed hoping to upgrade to 2 x 10/11 speed bike
Does it come with crank arm bolts ?
Any more information would be great.
Hi, this chainset will work with 7, 8 & 9 speed & will work with JIS square taper bottom brackets. Crank Arm Bolts are not supplied with the chainset but can be purchased under part code #3455. Regards
