Hey all,

Was chasing some advice/opinions on possible setups for a new bike.

Bike comes with dura ace 9100 cranks and ceramic speed pf30 bb to suit. I'm very keen to get a p2m ng eco hence have to get new crank.

Option 1. get a rotor aldhu 24mm crank, keem the ceramic speed BB, use p2m and probably praxis rings - benefit is keeping the better BB, drawback is i don't like the aesthetics of the rotor cranks.

Option 2. go praxis zayante m30 crank, replace the BB with the praxis m30 cermaic bb and use praxis rings - benefit is the uniformity (and better performing) crank setup, drawback is losing the ceramicspeed BB.

Option 3/4. give up on the p2m spider, either use a pioneer pm or vector 3?

As always, thanks for any help :)

Are you sure your frame is pf30? That's not the ideal shell for use with shimano cranks.

Please confirm. You have some options if you can run a 30mm x 68mm spindle like pf30 can.

Assiomas or Vector 3s unless you ride gravel or prefer other systems like SPD-SL or Speedplay.

Yeah - I'm getting the Ventum NS1 and here are the specs which confirm PF30 and Dura Ace cranks -https://2sno9k2jkirf37e3pk1df398-wpengi ... ations.pdf

Why not just get it with the Pioneer power meter?

to be honest thats where i'm leaning too.. its going to be $500aud cheaper to do it with that for me than to get the zayante cranks/rings/bb and p2m.

Just hoping the newer pioneer is better than the previous two gens which seem to have mixed reviews. https://www.pioneerelectronics.com/PUSA ... OWER+METER
