Rated 3.9 out of 5 by 8 reviewers.
Rated 5 out of 5 by Excellent No Issues getting the device to seat in the carbon steerer tube of my SID WC XX Shocks. Looks Good. Does exactly what it is supposed to do. I actually like it better than the included compressor from Rock Shox. 01 August 2014
Rated 4 out of 5 by Very quick to fit and holds well Very quick to fit, holds well and does what it says on the tin (like ronseal), so would recommend, 08 July 2014
Rated 5 out of 5 by Great value, excellent This product is a good value for your money, i bought one for my tribike now im buying it again for my road bike. You can go wrong with this. 17 June 2014
Rated 5 out of 5 by Works well I ordered this to use with a set of RockShox SID with a carbon steerer, I was a little dubious, as other reviews had talked about it slipping in the tube. For me it was as easy as pie to fit, simply slide it in, screw down with a 5mm hex key until it bit and then use 6mm hex key to pre load, works really well 11 February 2014
Rated 2 out of 5 by Poor Bought this for a carbon steerer. No good. Did not bite enough to tighten the top cap properly so I didn't even got out on the bike with this. Ended up using the deda bung which is longer and tightens in separately from the top cap. 06 June 2013
Rated 4 out of 5 by Easy to use Can't see how this could fail to work, 5mm key expands bung (plenty rough enough to grip), 6mm key tightens top cap to preload bearing. Loses a star as there is no plug to prevent water collecting in the top. 23 December 2011
Rated 5 out of 5 by works much better than the stock one that came with my Felt, no probs with it at all 18 April 2010
Rated 1 out of 5 by Rubbish piece of kit This expanding bolt is very poor. The faces of the wedges are scored with emery paper but not sufficiently to grip the inner face of the carbon forks ( Principia by Mizuno)therefore meaning that I couldn't tighten up the stem onto the spacers. I had to replace it with one from Condor which had proper knurled faces to the wedge sections 05 June 2009
