i have been reading up on and following the progress of the team roller secondary driven clutch and it's efficiency to eliminate scrub and heating up. polaris has purchased the right to use them and many racers are now using them. BUT!! i need information from experienced trail riders as to whether they are as good for our trail sleds and are there any quirks with set up or rer applications as has been posted here with the hyper=lite secondary clutches. any info would be really appreciated....thanks...don.
