different clutch types

[just a number]

standard or Helix(paddle) is there any advantage/ disadvantage to either of them? what about the Kevlar/ceramic/standard/ material? I'm trying to make sense of it all. all input would be great.

well here's what I found out so far. http://www.valairinc.com/performance/selector.html has great info on materials.:thumbsup: so far I can't find the differences between the 2 designs of them.:mad2: I guess the hunt continues.

What I remember about clutches is that there are basically two different types Diaphram and Borg & Beck. Diaphram has a bunch of small fingers that generally speaking allow for more holding power with less pedal effort. The B & B uses a three finger system which hold good but requires more pedal effort. I don't know if it matters with a hydraulic clutch or not but back in the old days of mechanical linkage it made a big difference. On either system to increase holding power they upped the spring pressure. Then to further complicate things they started using different materials on the discs. The more aggresive the holding power the harsher the engagement. So clutches are much like everything else a compromise. How much harsh engagement can you stand. I personally like centerforce clutches which use the diaphram system andalso use what they call a dual friction disc. Harsh material on one side not so harsh on the other. When you let out the clutch it's kinda grabby initially but then it's easy to feather from there. All my rigs that have clutches in them use this setup and they are all mechanical linkage. Don't know if this helped or just muddied the water but it's my 2 cents.

atleast now I know what the B&B setup is. I'd heard of it but had no idea otherwise. any suggestions on materials?

I pretty much gave my preference on the last post.

what I ment was what materials did you get? organic, ceramic, kevlar?

 

[ak diesel driver]

I belive the dual friction is ceramic on one side and organic on the other but it's been to long. I'd check with centerforce.
