because the old venture skis where not the saddle less design so the rubber is different.should be thinner.you could try them if you dont have the apex rubber.might just be loose fit.
The rubber from the Venture is a little smailler..I just used the Apex rubber and it worked well..There is a little bit of slop in there but we will see when the white stuff arrives..What size of Venture do you have ??? What do you get for gas milage ???
