5.GENERAL NOTES ABOUT ASSEMBLY
This manual is not intended as a comprehensive assembly, use, service,
repair, or maintenance guide. Please see your Authorized Specialized
Retailer for all service, repairs, or maintenance. Your Authorized
Specialized Retailer may also be able to refer you to classes, clinics, or
books on bicycle use, service, repair, and maintenance.
In order to successfully build your bicycle, it’s very important
to follow the order of operations as outlined in this manual.
Modifying the order of assembly will result in a longer build
process.
Assembly of the front end of the bicycle is easiest with the rider’s
fit already determined (the steerer tube doesn’t need to be cut at
this time; it can stick out the top of the stem) prior to routing all the
housings and wires through the frame and fork.
To determine fit, it’s recommended to use a fit tool. If this isn’t
possible, perform a basic assembly of the wheels, drivetrain, and
front-end components without the brakes and housings. Once the
fit is complete, all the components need to be removed in order to
route the housings and wires.
Many bolts have a blue thread-locker patch on the threads to help
secure the bolt under torque. Repeated installation and removal
of a bolt may reduce the effectiveness of the patch. However, it can
be replaced with the application of a liquid blue thread-locker.
5.1. TIRE SIZES
Tire sizes vary significantly from brand to brand. CEN standards require
a minimum of 6 mm of clearance between the frame/fork and the tires.
When choosing a wheel and tire combo, factor in enough clearance for the
conditions, setup, and wheel flex.
5.2. BOTTOM BRACKET
The Crux frame uses a 68 mm standard BSA threaded design bottom
bracket.
Before installing the bottom bracket (BB) and crank, make sure all
housings and wires are routed through the frame.
Grease the threads, install the BB, and torque according to the
manufacturer’s instructions.
CAUTION: Do not face the bottom bracket shell! This can prevent
proper installation of the crank. Your Specialized frame does not
require any bottom bracket shell pre-installation preparation, as
all surfaces have been precisely machined to specific tolerances
at the factory for proper interface with a compatible crankset.
Please refer to the manufacturer’s instructions for crank and
bottom bracket installation.
CAUTION: Always use a bottom bracket equipped with a sleeve
between the two cups. Running a bottom bracket without the
sleeve can result in housings and/or wires contacting the bottom
bracket spindle, which can result in wear.
5.3. RECOMMENDED TIRE PRESSURES
The tires must be inflated, periodically checked, and re-inflated using a
pump with an accurate pressure gauge.
Pump the tires up to your desired pressure. Refer to the tire’s sidewall for
pressure range. Check your wheel manual or decal on the rim itself to see
if your wheels have a maximum pressure limit. Do not exceed it.
WARNING! Never inflate a tire beyond the maximum pressure
marked on the tire’s sidewall or the maximum pressure limit
specified by the wheel manufacturer, whichever is lower. Failure
to follow this warning may cause the tire to blow off the rim and
may result in serious personal injury.
