5 arm thorn cranks.
19 Jul 2020
I have an older thorn 110 bcd 5 arm crank arms which I would like to upgrade to 10 speed deore 3x . Do you have a triplet set like this one for that bcd or what chainrings would you recomend I get to ensure smooth gear changing.
Easiest thing would be to use; SJS Cycles part number : 18493A0 or SJS Cycles part number : 42308L172

This will possibly be cheaper than buying all new rings.

Can i use these with shimano xt Hollowtech triple crankset. Thanks

Yes, these would be suitable if older than current series - currently the pattern is 104bcd but not symmetrical.

My question was not for the plateaux but for the crank itself

My question was not for the plateaux but for the crank itself ? My error . So the Crankset Mk2 is definitely not an asymetrical ? Thks
Hi there,

The crankset is definitely not asymmetrical.

Hi there,

The BCD on this is not asymmetric.

Would It Be Possible To Get A Thorn Chainwheelset 22T/36T/Chainguard?
07 Jun 2016
Hi there.
I am looking for a 22T/36T/Chainguard configuration to use on a Thorn tripple crankset that I want to order. I have not seen a 36T (middle) Thorn chainwheel on your website. Would it be possible to get a Thorn chainwheelset 22T/36T/Chainguard?

You would be able to achieve this, you'll need to purchase a 22 and 36T chainring separately. There aren't any Thorn 36T chainrings, but you can easily use one from an after market company like Middleburn, just select the 90ID option.
