Impossible to install - very misleading, avoidAs my postie will testify, I have bought many products form Wiggle; but this has been a rare bad experience. As a reasonably competent home mechanic I found the installation impossible without risking serious damage to the bike.
The Hope installation video shows the unit dropping into the steerer tube - do not be misled, this will probably not be the case. Even loosening the unit to its utmost, it is probably still about 0.75mm over-width (on a Canyon carbon tube). Searching the web this is common experience and it looks like only a combination of brute force with a hammer and chamfering the steerer tube will get it in. I am not prepared to do that and recommend others to think carefully before purchasing.
Of course after multiple fails to install, grease etc, the product is now used and impossible to return so has to go in the 'lost causes' parts bin the workshop!

ExcellentEasy to fit and adjust - so much better than a cheap star washer. And made in the UK.

Does the job nicely - but did not fit ENVE forksI ordered this to enable me to slam my stem on my ENVE fork (as the expander plug has a large lip which extends above the stem.
Unfortunately it is too big to fit inside an ENVE steerer (carbon is too thick), so be aware if you have them. Ended up using on another bike with an alloy steerer, where it fitted a treat. Nice quality, well made item - just does not fit some carbon steerers.
Does this fit 1"1/8 or 1" steerer tubes? Carbon or alloy or both?
Reviews about problems fitting to 3T Funda forks. Is the expander too big to go into the steerer in these cases?
Asked by: kssl
1 1/8" alloy steerers. Carbon steerers have a thicker wall and so have a smaller internal diameter. You need to order a Carbon specific bung which is smaller and won't damage the inside of the steerer tube.

If I already have a star-fangled nut fitted, can I still use a Head Doctor?
Asked by: castle
It depends on how deep the star nut is set, if it is shallow then there will not be enough for the Hed Doctor to fit but if it is deeper down you may be able to use it. Worst case scenario you just pound the star nut deeper into your head tube so it fits

fitting inside tube
do you have to use a srewdriver down the middle of this and tap it home, as it says it fits all tubes but its seems really tight to me, I've loosed it off as much as possible but its still not fitting in easily
Asked by: golffinder
We would not advise using a screwdriver to fit this product.
If you are having issues fitting this please visit your local bike shop.

1" Threadless Headset
I realise that this is made for 1" 1/8 steerers but the Hope tech website says that the maximum expansion is 26.6mm so I presume it will fit smaller? I'm interested in a tifosi carbon fork and would it be possible for you to check? Many thanks.
Asked by: barfuss
I can confirm that this is designed for a steerer tube of 1 1/8th as the inner diameter of the steerer is 26.6. I can confirm that this is not compatible with a 1" steerer tube. I hope this helps.

Does this fit 1.25 or 1 inch steerer tubes? Carbon or alloy steerers?
Asked by: kssl
I'm running one of these on a 1.25" steerer with no problems. Works great with alloy steerers and I believe it is okay to use on carbon steerers as the design spreads the pressure out.

Will the Head Doctor fit a tapered fork?
Hi,
I'm interested in fitting this to a Rockshox XC32 fork with a tapered steered. Will this work and if not are there are any other options rather than the star fangled nut for a tapered fork?
Cheers
Asked by: pedrosC
yes because the top of the steerer tube is 1 1/8

Hi I just ordered one of these and I think it mite be the wrong one as I have a full carbon steer should I have got the pro headset expander?
Asked by: MarkDyer
I've got one fitted in a carbon steerer and trust me it wasn't easy to do. I ended up removing the rubber ring and "modifying the aluminium some what. Fit's like a glove now, one that will never come off!!
Hope stuff is usually top quality but why this has to be made so tight is beyond me?
