Thoughts about using a button clutch and shift speed.

[svensdream]

team secondaries are less efficiant becouse they only use a pressure spring to controll upshift and backshift. so by the time you get them to backshift properly there is usualy to much spring to make they upshift. a button clutch has a torsional spring that is preloaded as to force a backshift without hindering up shift. when a clutch fights an upshift that creates belt heat, which is less efficiant (ie. team clutches). as far as springs and helixes, if it's having a hard time out of the hole you can up the engagement of the primary, but this is not the best cure, but something is the only option. the helix is the main control of upshift, if the helix is to steep on the initial than it will upshift to soon, if it is to shallow that it won't upshift fast enough and will feel slow. the secondary spring uses pressure and torsion to control the shift, since the spring is twisting to make the back shift not as much pressure is needed compared to a team

helix angle

Ok just for my info. If your running a 50/36 your initial 50 will upshift quicker
so a 45/32 will slow the upshift and as far as backshifting the 45/32 would backshift sooner is that right ?

yes the 50 will upshift quicker, the angles doen't have as much to do with the backshift as much as the spring does. the final angle on the helix should be what ever the motor will pull.
