Introduction
Introduction sheet for PHYSIS MTB handlebar
INSTRUCTION MANUAL
The handlebar is made of extremely strong carbon fiber and highly resistant to tears, due to the nature of the material, it is vulnerable to pressure
or to be damaged by sharp edges. Therefore, we must ask you to follow the safety instructions below.
• If there are sharp edges on the fastening parts, they must be smoothed out before attaching the handlebar.
• Take care that no dirt or metal chips get caught inside the tightening zone.
• Do not puncture the handlebars.
• Observe the permitted tightening torques!
Rod: 3 Nm | Lever fixing: 1.5 to 2 Nm
• Apply the insert paste included in the tightening area. This paste increases friction and reduces the necessary tightening.
• Do not tighten the screws to the maximum values specified initially. Start with the lowest values specified and verify that the connection is
secure enough. If necessary, increase the tightening torques, but do not exceed the specified maximum.
• If the specified maximum values are exceeded, you put your safety and health at risk and the warranty expires.
MTB HANDLEBAR
Clean all contact zones with between stem handlebar.
Do not lubricate the stem clamp and handlebar surface. It is important that the
contacting surfaces be abrasive enough for a secure grip. The use of friction paste is
strongly recommended.
Place the handlebar (A) between the stem body (B) and the stem frontal plate (C).
Tight the frontal plate bolts until reach a light clamp force on the handlebar, tight
the bolts evenly, use small increments while making sure that the gap between stem
body and frontal plate is absolutely equal in the four bolts. Use the handlebar marks to
center and adjust the angle to desired position.
Using a torque wrench with an appropriate hex key, tight the frontal plate bolts, in
one-turn increments and in rotation, to the recommended torque. Use a cross pattern
tightening sequence (1-4-2-3).
Torque values (N) are the maximum torque allowed, not the recommended torque.
Start with a lower torque and check if the connection is tight enough. If necessary
increase the tightening torque or apply friction paste, do not exceed the maximum
torque. The use of friction paste reduces the amount of necessary clamp torque and
prevents risk of rupture. Insufficient tightening can cause serious injury or death.
Adjust the width, only if necessary, use the lines at the end of the handlebar as
reference and cut the handlebar to the desired width. Use the same reference mark on
each side.
The assembly of the brake levers and shifters must be done carefully. Make sure that
are free of sharp edges. If necessary remove them with a thin sand paper. Remember,
this parts should be tighten with the minimal torque to operate. Normally 2-3 Nm /
18-26 in.lbs. Please check the manual of each part and follow the instructions of each
manufacturer.
