So ride the Chubby and let it Rip! Note: The Noleen Chubby and Chubby LT come in a Standard size (for bicycles with 90mm to 125mm head tubes) and a Long size (for bicycles with 126mm to 160mm head tubes). Make sure that you have the correct size Chubby. If you have further questions about the correct size, see the Installation section. - Page 4 Some headtubes need to be “faced” in order to hold the headset cups properly. If you believe that your headtube needs to be faced, consult your local K2 Bike / Noleen dealer or other qualified bicycle dealer.
- Page 5 You will need to know the headtube length and the headset stack height to find this measurement. This is VERY IMPORTANT! The maximum amount of room between the triple clamps for our Chubby and Chubby LT forks are:...
- Page 6 Step #5 - Decide where you want the upper triple clamp mounted. The position of the upper triple clamp on the Chubby forks is somewhat flexible. You can place the upper triple clamp directly on top of the headset, or you can space it up so that it clamps up higher on the stanchions. Remember: the position of the lower triple clamp is FIXED, and should not be moved up or down.
- Page 7 The Spring Rate of a spring is the amount of load required to compress that spring one inch. This definition applies mainly to coil springs and not to MCU springs. Since the Chubby and Chubby LT use a combination of MCU springs and a coil spring, the spring chart below refers to combina- tions of MCU springs and not actual spring rates.
- Page 8 Noleen forks should all be set up properly with a certain amount of sag. The optimum sag amount for all of our front suspension systems is 20% of the total wheel travel. For example: Our Chubby LT has 125mm / 5 in. of travel. To calculate the optimum sag for this fork, multiply 125mm by .2. The answer Adjusting Preload gives you a suggested sag , which for the Chubby is 25mm / 1 in.
