Rear Shock Setup:Because it is highly likely the original rear shocks on older models are repaired/replaced/ upgraded throughout the lifetime of the frame, we offer some very basic tuning guidelines, and recommend using the original rear shock manufacturers manual for more detailed set-up for the specific rear shock you have. Contact the rear shock manufacturer for info if you do not have it.The key component for set-up with any rear shock here is sag. Once you have that set-up correctly, the rest of the shock settings are fine tuning adjustments (Rebound and Compres- sion damping, etc.) set to rider preference.Recommended sag is 10-15mm at the shock shaft for 152mm Travel set-up or 16-20mm for 178mm Travel set-up - This equates to approximately 15-25% of the total rear wheel travel. Less sag = a firmer suspension feel.For Air rear shocks, set the air pressure to match the recommended sag. This varies greatly by rear shock used.For Coil rear shocks here is a rough spring size to weight guideline for average coil shocks. This can vary based on rear shock model and manufacturer (Below is with a Fox Coil used).100-130lbs - 400#140-160lbs - 450#170-200lbs - 500#210-240lbs - 550-600#
Rear Shock Notes:Rear Shock and Travel Upgrade for 1998-2001 framesThe 1999-2001 Bullit came with the 7.875" x 2.25" size rear shock as standard and152mm of total rear wheel travel. Riders with pre-2002 model Bullit frames can upgrade to a 8.5" x 2.5" size rear shock, and get 178mm of rear wheel travel. Just the correct 8.5" x 2.5" size rear shock is required. You will lose the adjustability of the shock shuttle (a worthwhile tradeoff in our opinion), as you need to put the shock shuttle all the way in the forward position, tighten it up, and leave it there.You can also upgrade to the 2002-on two position style shock shuttle, but you will still need to keep it in the forward position.All Bullit models from 2002-on came with the 8.5" x 2.5" size rear shock as standard, get 178mm of rear wheel travel and can still use both the forward and aft shock shuttle shuttle positions.
