RPANTAHI Carbon Cranks
« on: May 16, 2026, 01:35:58 PM »
Considering rolling the dice on these as I don't want to switch to a DUB BB, and these are the cheapest TI 24mm Carbon cranks I can find. Alternative would just be to go with the Ultegra crankset. Anyone have any thoughts or experience with em?

The thinkrider PP5 has been proven to be unreliable after a sprint, so I wouldn’t recommend it. It always reads too high after you give it some beans.

Good to know! Thanks for your input. What chainrings have you used with em?

If you want to pair with THINKRIDER PP5 powermeter, then buy the THINKRIDER power meter and crank package set, if you buy Rpanthai cranks to pair THINKRIDER power meter, you have to buy the spacer from THINKRIDER.

I've got this crankarm matched to a PP5 powermeter and the fit is fine, no spacer is required. The PP5 sits slightly higher than the crank and the lockring can be tightened down to spec.

I picked up my RPantahi crankset a week ago and I'm impressed. The Easton mounting system is very solid. I'm also using a PP5 power meter. I know it doesn't have the best reputation, but I picked it up for about $60 usd with a crankset, so for the price I can't complain too much.

Also spare parts for Hudud crankset fit the RPantahi crankset from this AliEx store. I picked up a spare 24mm easton lock ring just in case:

I'd definitely buy another one if it came up for a good price.  :)

I have the same chainrings in black color and they have been great so far.  How do you like them?

They're very solid chainrings. Shifting has been solid. I even have friends who've bought aero chainrings after seeing mine, so it's a bit popular in that regards.  ;D

Also bought RPantahi and PP5 power meter.  Couldn’t make them to work so I replaced the PP5 pm with a Sigeyi one.  Put VMX 50/36 chainring on the crankset for lightweight benefit.  The whole setup is much lighter than SRAM Red crankset with PM.  Been riding it for the last 3 months, very happy with it.
