Hiya,
I'm in need of a very low stack height headset. It needs to be about 24mm in total. Anyone know of one this small?
I understand the Crank Brothers ones are about this but I've read a few reviews about them being poorly sealed.
Cheers

Yep, Crank Bros are 21mm. I've used both the Iodine and Opium with no bearing problems in the Welsh mud. [url= 
]I have a lightly used Opium C for sale[/url] as my new frame has a 1.5 headtube, complete with original box and instructions - bearings run smoothly and top cap and star nut are new and unused. £30 posted if anyone's interested 🙂
I've got a iodine am h/set and accoding to the paperwork the stack height is 20.3 mm. also for sale about 20 hrs use £25 posted.(is this the new for sale forum ?)....... 😆
Im one of the "crank brothers are crap" brigade sorry, I pulled a cobalt after a month and it was full of rust and gunk. If you have no alternative (and there basically aren't any) then make sure you use both a gator on the bottom, fit the rubber seals properly and keep them well lubed / greased.
Other options I went through was a single bolt clamp stem (NC-17 and Spike) before finally admitting defeat and replacing the CSU.
