SHOCK SETUP

Your Transition frame is fully equipped with GiddyUp suspension technology. The custom tuned
rear shock is designed to work perfectly in conjunction with the frame’s leverage curve to provide
superb pedaling performance and downhill small and big bump sensitivity. As a starting point all
GiddyUp bikes are recommended to have 32-35% sag. Adjustments like rebound and compression
are all personal preference settings that should be adjusted to your personal riding style and
preferences. Consult your shock manual for information about how to adjust your rear shock.

MAINTENANCE & INSPECTION

It is crucial to the longevity of your Transition frame that you properly maintain and inspect it. We

recommend that all service be done by a qualied Transition Bikes dealer.

Before you begin any ride it is very important to inspect your entire frame for any cracks, loose
pivots or bolts, and properly functioning bearings. In addition to inspecting your frame, checking
your entire bike to make sure it is working properly must happen before every ride. This includes
but is not limited to checking tire pressure, ensuring the wheels are secure to the frame and fork,
all components and brake bolts are tight and pedals are secure. Also, a quick check of your brake
pads and brakes to insure they are working properly and ready to ride. If you are unsure of what
you need to check on your bike to make sure it is safe, please bring your bike to a bicycle shop to
have them inspect and maintain it before you begin a ride.

TORQUE SETTINGS

Proper torque ratings for the hardware used on this product are crucial to keeping your frame
working in proper order and preventing damage to the frame and pivots during use. Damage
caused by over/under torquing will not be covered by the warranty on this product. All torque
settings can be found on the exploded frame view on page 3 of this document.

Main Pivot

The main bottom bracket pivot on your GiddyUp family bike is equipped with a collet style hardware
system. This type of pivot requires a two step process to tighten correctly. Step 1. removed the main
pivot screw (A) with a 5mm hex wrench, then slide out main pivot taper nut (B). Step 2. With an 8mm

hex wrench tighten the main pivot axle (C) clockwise until you reach the specied torque of 19nm.
Reinstall the main pivot screw with the taper nut to the specied torque of 10nm. The pressure from

the main pivot screw and taper nut will help to maintain correct torque on the main pivot axle and

increases the rear end sti󰀨ness of your frame.

BEARINGS

Take apart all the linkage and rocker arms to inspect the bearings to see if they are rotating smoothly.

If they do not feel smooth or are seized up, you should replace the a󰀨ected bearings. Always replace

bearings in pairs.

WARRANTY

Your Transition frame comes with a 3 year manufacturing defect warranty and a lifetime crash

keep riding and has a smile on their face.
