RockShox Carbon Steerer... Expander or HeadLock head set adj

GTD.

Just bought a RockShox Reba fork that has a carbon crown and steerer

What would be better,

a headlock type headset adjuster?

or an expander?






I also have an SKS Shockboard front mud guard, if I fit a headlock type adjuster will I still be able to fit this?

unless the thread of the expander bolt goes out the bottom part then I could possiblyfit the bracket for the shock board with a thin stainless nut?

if you use a bolt through set up, you will not be able to use the mud guard.

From the looks of it, there is no lower hole on the crown to fit a headlock type device through either.

My new 2011 rev with a carbon taper steer came with a expander type.

GTD.

Damn didn't notice there was no though hole

oh well expander it is then, I was looking at headlocks as a kind of fail safe if the worse happens and to add a bit more strength and security.

was just looking at a THE Stem Lock and Pro DH mudguards in carbon effect... bang goes that idea

Going to have to change mudguard mount, unless plastic can be glued to carbon with a bit of epoxy or something as I could glue my spare q/r mudguard bracket to the base of the crown

I'm guessing it's a bad idea to use a star fangled nut, right? Cause it would gouge the carbon?

correct and it can cause the fork to fail.

Fair enough. I suspected as much, but just wanted some clarification.

Does not stop RS supplying a expander and a SFN with 2011 rev world cups. I recon a few people will try using them as well as the instructions dont mention anything.

yes it does.

Suspension fork IN STALLATION
It is extremely important that your RockShox suspension fork (fork) is installed correctly by a qualified
bicycle mechanic. Improperly installed forks are extremely dangerous and can result in severe
and/or fatal injuries.
1. Remove the existing fork from the bicycle. Measure the RockShox steerer tube against the length
of the existing one as you may need to cut the RockShox steerer tube. If your RockShox fork has a
tapered steerer tube, be sure to leave enough steerer above the taper in order to clamp the stem.
Prior to cutting, consult your stem manufacturer's instructions to determine the length of steerer tube
required to clamp the stem.
Aluminum or steel crown-steerer: mark the steerer tube and cut to the proper length.
Dual crown-steerer: mark the steerer tube and cut to the proper length. If using a direct mount stem
make sure 5 mm of steerer tube is exposed above the upper crown and cut to the proper length.
Carbon crown-steerer: the steerer tube must be cut flush with the top of the stem. Apply masking
tape at the cut location to help prevent the carbon from fraying. Use a 28-tooth blade (minimum) and
cut to the proper length. Smooth the entire cut area with 400 grit sand paper.
2. Remove the crown race from the existing fork and install it firmly against the RockShox crown Use a
39.8 mm crown race for 1 1/2" steerer tubes and a 29.9 mm crown race for 1 1/8" steerer tubes.
Do not damage the surface of the carbon crown-steerer when removing and installing the crown
race.
3. Aluiminum or steel crown-steerer: install a star nut or headset compression device into the steerer
tube.
Carbon crown-steerer: install an expansion style plug into the steerer tube. Do not apply more than
11.3 N·m (100 in-lb) of torque to the expansion plug bolt. Do not use star nuts. Torque values may
vary depending on headset design and condition.
