Can I replace a 48t chainring whit this?
29 Mar 2020
I have a triple shimano crankset 48-36-26 and I'd like to replace 48t chainring with a chainguard, could you please give me a suggestion?
Yes, you could just unbolt the outer and fit this, or fit XL bolts, spacers and this as a bash in the 4th ring position.

Thanks - 30/03/20
To use with your cranks 31813L150 - standard double bolts or something else?

Also please confirm - 107 BB for Rohloff chainline using 8540 splined carrier.
You will need to use a double chainring bolt, using the chainring in the middle position, you will need a 110mm BB.

I have triple chainrings on a Truvative crank. What length of bolt would I need to fasten this guard securely.
Hi, you will need the following, item #11987, item #254 x 2 to attach either side of the chainring sleeves & a pack of item #33189 to give you the correct 4.6mm of spacing. Regards
