I have no objection to going down the second hand route if the cost and condition are OK.
I'm a bit confused by a term used by Smithie ^^^ up there.
He said ..... "bottle+whip £150."
What's a Whip?
Also, the last link provided by Moxy showing clamp systems almost scared me to death. It all looks more complicated than my Jag's electric system. One reason why, if I go down the PCP route, I'm hoping to buy the full kit from the same person, either trade or private.
Many thanks for your info, guys,
Steve
