I run Spykes on my KHS (with Paul levers) because I was tired of dealing with hydraulic fluid leaks. They're strong enough and I like them but there's no way they can be adjusted to resemble the feel of a nice hydraulic disc. There's a relatively long throw to engagement and they don't feel as solid with cable stretch.
On topic - I've been looking for mountable brake studs for my 24" BMX project - thanks!
Good to know thanks.
When you say long throw (at the lever) to engagement , does this also apply on the caliper side meaning lower chances of the rotor rubbing on the pads? Could you tell me more about which lever model you are using?
