Just bought a Cannondale F4 (2008) Headshok from Evans. Have to say I got a pretty good deal - the seatpost was scratched on the one in the shop so they swopped it for a Thomson and did a deal on some SPDs. Getting it home on the tube was a bit of a laugh, but it is now snugly tucked up in my garage next to my 8 year old P7 (to be turned into a singlespeed - watch this space)

Now, the question -

I'm used to Magura hydraulic brakes (old raceline rim brakes... remember those?) so discs feel a little weird. I know they need to scrub in, but can the lever be a adjusted to give more feel. It seems the lever is very spongy, although it does lock up at about 50% travel. For info, they are Avid Juicy 3's.

As you say, the pads need bedding in, so will improve once that's happened. Some people reckon the best way to do this is to do 8-12 full-on emergency stops from a decent speed, using as much braking force as you can without locking up. then pour a small amount of water on the rotor, and if it sizzles, they should be bedded in. If it doesn't, then repeat.

You can adjust the lever reach on juicy 3's, to bring the lever closer to the bar for more comfort, but it doesn't have any effect on the pad feel. It's the tiny (2mm hex?) grub screw on the inside of the lever. See the user's manual for details. I think it's 1 rotation for 1mm of travel.

It's one click for 1mm of throw.

The brakes may need a bleed depending on how long the bike has been sitting in the shop. Avids are prone to need bleeding if they are left unused for a long time.

You'll find that you have to adjust your braking style to get used / the best out of disc brakes. They are soooo much more powerful than all rim brakes so you need to adjust to them. If they are not more powerful than your rim brakes then they'll need a service (initial bedding in of pads aside).

Avid Juicy brakes have one of the best 'feels' of all the hydraulic brakes. It's worth visiting sram.com and reading through the tech manual if you didn't get one with the bike, as this will help you get the best out of the brakes.
