You might have already heard this, but some people have voiced the opinion that the stock RP3 is overdamped for lighter (sub-160lbs) riders.gukachu said:i just picked up a 2005 model reign frame. i noticed the 2006 models have switched to a fox rp3. i would like to swap my swinger 3-way out for an rp3, which i also plan to send to PUSH industries for modification. is there any reason i can't/shouldn't use this shock on this frame? i dunno if this helps but it can't hurt; the frame size is 16" and i'm around 115lbs. thanks!
