Does anyone run or have experience with the OSP clutch kit? I'm debating between there kit and the Big Venom. The OSP is weights with a Primary spring and the Big Venom is weights with a Secondary spring. I know there is alot of debate on what is better and I ready a bunch of the forums but I didn't find much on the OSP kit. They OSP is a little cheaper with there Black Friday Deal. Or should I just spend the extra money and get the Ulmer?

Thanks

I don't believe the OSP comes with a Primary Spring despite the picture on their website. I bought their weights last year and have yet to put them on. I called them about the Spring and they said the clutch kit does not come with a Spring. I have the Big Venom kit on now, it will certainly test the OSP once we get snow.
 
i am almost ready to buy the big venom kit, as in now!! what do you not like about the big venom kit, just asking, as why you are so willing to buy another set up
 
i bought the thunder products kit, talked to lonn a few times, great guy, the kit is put together real nice i also got the belt adjuster, i havent ridden the sled yet but so far very impressed with the customer service and the quality of the kit

I love the Big Venom kit. I had just bought both last year around the same time but never had a chance to try the OSP. I absolutely love the Big Venom though. I just want to give the OSP one a try so I have a comparison. I also have Ulmers too.
 
only thing i hate is how noisy the primary is, 2500 rpm shes noisy, not a thunder products issue im just saying lol
 
Once you guys use magnets you will never go back to anything else. It's that easy to make changes.
 
I think I'm gonna go with the big venom and the ops belt adjuster.

I was on the ulmer site today and I can't even find the clutch kit now.

For me, i think I'll let it all play out, then see what's what.
 
What is this?
Look at the pics OSP posted. to change wieght you just put magnets in the pockets in the wieghts. No tools other than tool to compress clutch and I use allen wrench to remove magnets. All positions are accesable with wieghts still in clutch. I can do it in the dark middle of nowhere and wearing gloves. It makes clutching FUN! HUGE timesaver.
 
Go with the Big Venom kit and you will not regret it. Its the best kit for the vipers and it is so easy to install and adjust.
 
Just pulled the trigger on a big venom kit...good guy and fast shipping
 
I'll agree with the ease of adjustability with magnet's,but most people don't mod a couple times a week :eek:(cannondale),set it, forget it and ride.
