Rotor 3D 1x Oval NW options

[NotSoBigBen]

I would like to run a 34t Oval on this Rotor 3D crank, just wondering what would be the best option ... A single blade but wondering about that 5*74/110 BCD or I notice that the 'spider' could possibly be replaced?

 

Where to easiest source it if it's available?

Thanks, I'll take that spider off and check it out, wonder if a SRAM or other spider might fit?

Doubt it , it looks similar to the raceface set up where a big lock nut secures the spider into place with A specific tool.

 

Sram spiders fix onto the crank with 3 bolts.

May have to man up I suppose but just to complicate it it's also 5 bolt [emoji849]

The 110BCD rings are 5-bolt.

 

Is that a 'standard' spider? ie. will SRAM 104BCD spider fit?

The BA man says not but I'll take it off tomorrow, it needs a 'special' tool though

If it is a standard spider - ie: Sram, you can just as well save some money and mount a sram direct mount chainring. But I doubt that is the case, the spider looks specific to Rotor. Just pop the distributors an email and ask them if they have a 104bcd spuder for your crankset - if so, there are a plethora of chainrings available.
