I am pretty sure I have about 18 grams with the 412 ramps with my RB kit. My memory is sketchy sometimes but i wrote it down....somewhere in the shop, but where I don't remember. Kids that never sleep have made my memory like Swiss cheese. I rode mcbride at about 6000 ft on clicker 4, and used 5 on some riding where we hit over 7000 ft. Pulled hard with consistent rpm, so far I like it better than the 441 ramps.
Last year had RB kit with stock 441 ramps , 15.3 gr pin weight , 19 tooth ! had trouble keeping consistent RPM ! This year went to 412 ramp , geared up to 20 tooth , running 17.5 grams ! hard to tell yet but first ride out with 10 inches of fresh on long steep pull - rpm was 8000rpm all the way ! happy with the new ramps !
