Specialized rockhopper adjustable dropout rh dropout Manuel D’Utilisation

2

Tighten the two drive side bolts so that they’re fixed, but not 
torqued to specification yet.

Single-Speed style: Pull the wheel backward, so that the chain 
is properly tensioned.

Derailleur style: Push the wheel all the way forward.

Make sure the tire is centered between the chainstays.

Torque the drive side and non-drive side bolts to 

250 in-lbf.

NOTE: Do not use a multi-tool or 3-way Allen key to torque 
the bolts, they will not apply a high enough torque. Only use a 
torque wrench, or a long handle Allen key that can apply the 
same torque as a torque wrench.

WARNING! Insufficient torque may damage the dropouts/frame 
and can result in serious personal injury or death.

Apply downward force with body weight on the saddle and 
apply the rear brake, then roll the bike forward slightly. This 
will rotate the dropout as far forward as possible, so that the 
dropout won’t be able to rotate under braking while riding.

Once the brake and dropout are rotated, make sure the wheel 
is still centered, then tighten the left dropout so that it’s fixed.
