Mr Hinz|Good compression plug at a good price. The plug is nice and long which is necessary to provide the best strength and support to the steerer tube where the stem is attached.
Mr SmutsGreat product that allows you to SAFELY run a few spacers above your stem without a risk of carbon steerer failure.
Chris in VanGreat price for an expander that just works.
Mr SalihDoes the job nicely
Mr DeeganVery easy to fit. Used some carbon grip paste to fit into a carbon steerer. Top job
DWSimple to fit, works well, good value - and usual good service from Merlin
Sebastian HorseradishWell made and fast delivery
Mr MilneFits well and seems of good quality
Mr OsborneNice quality, does the job well, exceptional value.
LHPLooked long and wide for a solution to my slippery headset problem for some time. This appeared to be the answer, and has proven to be performing to date. Very good price and service.
JohnVery well engineered unit which provides maximum support to the fork steerer tube against the crushing force of the stem clamp. Only negative to this product is that the instructions that are included are wrong and should be corrected. Very economical, well engineered, and manufactured.
Mr mckenzieGreat for supporting carbon fork steerer against damage from stem bolt tightening. Installation was straightforward.
AlistairNicely made little piece, works well and the top cap even looks good (slightly different design to that in the picture)
SpencerExcellent product - far superior to the stock item that failed on the bike. Quick and easy to fit - headset now 100% solid. Would buy this product again if needed for other bikes
K9This is a very well made piece of kit. Very light, and great workmanship. I purchased two and am very happy with them.
Mr AraujoGreat product, with a large area to grip the steerer tube and distribute the pressure. The carbon top cap doesn't make much of a difference. If it wasn't in stock I'd buy the other versions without hesitation.
Andy CVery impressed with this, works better than most headset bungs I've used and at half the price!
FaraciCompressor works great, better than the unit I was using.
Mr TrollopeGreat piece of kit - fitted in minutes and very secure grip. Highly recommended.
Mr LiangExcellent product. I particularly like the design of the circular springs that hold the compression plug pieces in place as opposed to the rubber band used to old my old piece.
EarlStanViiAn excellent piece of kit. For various reasons, I wanted something other than a star nut for my aluminium steerer tube. The "PowerHead" looked like it fitted the bill, and is everything that I had hoped (It is sturdy, well-designed and well-made; The instructions are clear and include torque specifications for the inner and top-cap bolt. It looks good and is reusable.)
Mr LefortInstalled in seconds. distributes load nicely across 50mm of alloy expander. Wonderful for use with carbon forks. (Weight weenies beware though - they do weigh substantially more (58g) than other options).
Mr HumphreysBought this for forks with carbon steerer. Does the job perfectly and looks good too.
