Hello! I seek for your help. I have bought the blue ones at 17,5mm. Which is the appropriate length of the rubber for a 100cm roballen railgun?
 
for that thickness i would say 26 cm long for a 100 speargun
 
they've told me that about 54cm(it is railgun) would be ok. Aproximately 3,3 elongation
 
ist's about what Marwan said:
2*26=52cm
plus 2cm for the loop turn and you have 54cm
