Just a note, the order form on page 19 of the pneumatics manual does not list 24" for a stroke length for the 1-1/2" bore, but it also says "Please check the Bimba web site for available strokes in each bore size". Page 7 of the pneumatics manual also says "You can order the amount of stroke you require.", implying you can get whatever stroke you need (of course assuming its avalible). As said by oneangrydwarf the bimba site does list 24" stroke cylinders in 1-1/2" bore, which means you can get it.

Also, rule <R91> says you may use last year's kit pneumatic cylinders and solenoid valves - last year our team recieved two 24" stroke 1-1/2" bore cylinders as part of our 3 free cylinders, meaning we can use these because the rule says any cylinder avalible in the kit last year is also legal this year.
