ok here is a bit of info about the libre buggy....
Judith's buggy is a Libre Full Race buggy which is on bigfoot lights and a standard wide axle, you can upgrade to a wider axle if you really wanted.
There is nothing else added to Judith's buggy but there are options of putting extra weights on it, putting full big foots on it or putting disc wheels on it.
What wheels you use depends on what surface your going to be riding on.
I found the bigfoot lights are fine for Scottish beaches and handle damp beaches fine as well but, once you start hitting 40mph in the buggy it tends to loose its straight line ability but this can be combatted by putting full bigfoots on it, the disadvantage of this though is if you hit water at that speed the chances are the entire buggy will break loose and you will go sideways!! So you need to have a balance and know what your going to ride on. Disc wheels are fine for hard backed sand and work fine on wet beaches as well as there is less surface touching the sand but hit a soft spot of sand and you will stop or dig in!
One thing I am looking at doing to Judith's buggy is put more padding on the side rails though, the reason is when we were racing in France we were so powered up I was getting pulled in to the siderails when the kite was low and powered. This is easy enough to do though with some pipe lagging
As Judith said, the next time the buggy is empty sitting on the beach, give it a go. Its the best way to get to know a buggy, go for a ride in it.
Whats your reason for wanting a race buggy mate? Looking at joining the racing fleet??
