Identify this crank please!

[garethrl]

Hi folks,
Can anyone identify the crank in the photos below? I can't find any tell-take markings, and scanning through google image searches hasn't resolved it yet. For reference it's an ISIS crank - at least I think it is, I don't know how to distinguish between ISIS and Powerspline, for example. The arm length is 175mm and BCD is 110.

It has some distinctive profiling on the spider arms but I can't find a match. Has anyone seen one like this before?

Cheers,
Gareth.

I haven't, but man the arm profiles look very similar to the old SR cranks of the 80's. The splines not so much. 110 BCD suggests it was developed from an old touring/mountain bike crank. It could be an SR or Sugino product for a down market brand?

105 octalink thats been polished?

Not with those webs on the front.

TBH, it doesn't look like anything shimano.

Re:

Looks like a propitiatory brand to me, (Coda/Cannondale, Trek/Icon) not sure which brand though sorry

 

[garethrl]

It's definitely ISIS not Octalink - 8 splines not 8. So that counts Shimano out.

I think it's ISIS as opposed to Power Drive or Power Spline, since the spindle diameter is about 18mm (spline inner) 22mm (spline outer) but that doesn't get me any closer to identifying it!

I had originally thought Bontrager but can't find a particular model that matches it.

Cheers,
Gareth.

Re:

Icannot help sorry but it reminds me that mavic was intending on releasing this unusual black crankset with its stillborn Mektronic group

Bontrager Race, or Race Lite. Mid 90s i think. Have a Google. There are several versions. Some have those funny webs on the front. Think they were made by truvativ, but someone else may know better.

Knew I'd seen one before. (Was on a mates Trek)

Thanks Matt! So my Bontrager hunch was right after all, just couldn't find a match. I think you're right about the Truvativ connection also.

Now the next issue is to find a match left crank ...
