How to Set Up and Maintain Your Specialized Big Hit 1 Bike
The Specialized Big Hit 1 is a full suspension mountain bike designed for downhill racing and freeride riding. It features a durable aluminum frame, a coil-sprung rear shock, a Marzocchi fork, hydraulic disc brakes, and a SRAM drivetrain. The bike is built to handle rough terrain and big jumps, but it also requires proper setup and maintenance to perform well and last long.
In this article, we will show you how to set up and maintain your Specialized Big Hit 1 bike, based on the owner's manual that you can download from here. We will cover the following topics:

Seat Post Setup
The seat post of your Specialized Big Hit 1 bike has a minimum extension mark that indicates how far you can insert it into the frame. You should never insert the seat post below this mark, as it may damage the frame or compromise your safety. If you need a higher saddle position, you should replace the seat post with a longer one.
To adjust the seat post height, loosen the quick release lever on the seat collar, slide the seat post up or down to your desired position, and tighten the lever securely. Make sure the seat post is not twisted or tilted in the frame. You can also adjust the angle of the saddle by loosening the bolts under the seat clamp and tilting the saddle nose up or down. Tighten the bolts evenly after adjusting.
Frame Features
The frame of your Specialized Big Hit 1 bike has several features that enhance its performance and durability. Some of these features are:
A tapered head tube that provides more stiffness and strength to the front end of the bike.
A hydroformed down tube that reduces weight and increases rigidity.
A forged bottom bracket shell that integrates with an ISCG mount for chain guide compatibility.
A replaceable derailleur hanger that protects the frame from damage in case of a crash or impact.
A Horst Link rear suspension design that isolates pedaling forces from braking forces and provides a smooth and responsive ride.
A coil-sprung rear shock with adjustable preload, rebound, and compression damping.
Frame Geometry
The frame geometry of your Specialized Big Hit 1 bike affects how it handles and fits you. The frame geometry varies depending on the size of the frame (small, medium, or large) and the fork travel (170 mm or 200 mm). You can find the frame geometry chart in the owner's manual or on this page.
Some of the important measurements in the frame geometry chart are:
Top tube length: The horizontal distance from the center of the head tube to the center of the seat tube. This affects how stretched or compact you feel on the bike.
Standover height: The vertical distance from the ground to the top of the top tube. This affects how much clearance you have between your legs and the bike when standing over it.
Head tube angle: The angle between the head tube and the ground. This affects how stable or agile the bike feels when steering.
Seat tube angle: The angle between the seat tube and the ground. This affects how far forward or backward you sit on the bike.
Wheelbase: The horizontal distance between the centers of the front and rear wheels. This affects how stable or maneuverable the bike feels when riding.
Chainstay length: The horizontal distance between the center of the bottom bracket and the center of the rear axle. This affects how well the bike accelerates and corners.
