Hey I am new to the club and I saw that the spin session had a max of 19 bikes (with 23 people already signed up). I am guessing this means there won't be any spare for the session / there are no turbo trainers?
Welcome to the club!! Yes you will need to sign up for Wednesday spin/brick on a Sunday when Len puts the events up to get a spot. The ones signing up over 19 are hopeful someone drops out. There is another spin session on a Thursday night though which you can usually get a place for.
