Hi community!
For my winter project I am going to overhaul my Felt DA.
I have a Vision Trimax Pro TT30 Crankset installed. I need this thing to get off, but never did a crank removal on that kind of system, what tools do i need in order to be able to uninstall the crank? I am sure some of you have the same crank and did that a few times already!
Thanks for your help!
I found an image that should give the real mechanics enough information 
greetings, Nick
I believe it needs an 8mm allen head on NDS and elbow grease
.
I have the same crank on my DA
I had to bang mine out pretty hard.
After removing the non-drive side crank arm, I inserted an old screwdriver from the non-drive side, supported the drive side the best I could and tapped it out with a large hammer.
I use this to remove the bearings

Hello!
I also have a Felt DA (2012) that I am trying to overhaul. I ran into a similar problem with the crank. My vision trimax crank’s non-drive side crank arm has a piece that can be taken out with a 10 mm allen wrench (or 8 I forgot), but I seem to be missing the retaining ring (that circular piece with the 6 holes in it). It is my understanding that this ring is what makes it a self-extracting crank set, but my Felt is missing one. There are threads where the ring would go.
Interestingly enough, I have a Felt F75 road bike with an FSA crank that is also missing that retaining ring.
Does anyone know if that ring is necessary to take off the crank? or can I just remove the one bolt and yank the non-drive side crank off? I tried this method, but was hesitant to pull to hard for fear of damage.
Yes. That ring is pretty important to remove the crank arm / crank. This allows the screw to push on the crank arm, thereby removing it.
I suppose you could potentially remove the NDS crank arm by other means, such as getting between the BB and crank arm with a screwdriver and prying the NDS crank arm off. However, I think I’ve tried that once and failed miserably.
Alright, that is what i figured and was afraid of. Its odd that the shop that sold me the bikes didn’t supply that piece.
Any idea where I can get that retaining ring?
It is odd. I have always seen those cranks with the ring.
The good news is that this ring should be on virtually every FSA crank. I hope you can source / borrow one pretty easily.
I’ll start asking around. Thank you!
Thanks for the awnsers! I can work that out! And will have a closer look at the ring…or better if I have that ring!
I believe this is the part you are after. Or the “Crank Bolt Assembly” here
Hope that helps.
