If the stem is not inserted into the top nut to at least the “Minimum Insertion” mark, it is
possible to over-tighten the stem bolt and damage the fork steerer tube. If these instruc-
tions are not followed, it could cause an unsafe condition and risk injury to the rider.
Check steering tightness prior to riding by straddling the front wheel. Try turning the han-
dlebar. If you can turn it without turning the front wheel, the stem is too loose. Re-align
the handlebar with the front wheel and re-tighten the stem bolt.
