Jordan, Good question. I have checked through our data on this and cannot find an answer. From memory, I would judge the rim for want of a better word to be about 2mm wide. If it is critical, I would have to get someone to go to the stores with a caliper to measure one. Let us know if the approx figure is not good enough for your needs.

Andy, Not sure about the exact length but is likely to be around 400mm as you suggest.

John, There are no driven or idler sprockets available for these tracks, they simply stretch over a hub. we quote a wheel in the description that can be used in pairs to form a grooved drum to keep the track aligned.

Gareth, Sorry but we do not have that information available.

David, The actual dimensions are as per the description, namely 180mm long by 30mm wide.

Ihave just bought a pair of these and they are slightly too big for my needs. I have considered bigger wheels but is there a way of slightly shrinking the rubber, maybe by heating and cooling that might serve my purpose?

David, Sorry but we do not expect the tracks to shrink by heating and would not recommend that you try. We have no other suggestions to make apart from the obvious changes to the mechanical layout or wheel size.

Kevin, Tracks are supplied individually.

Shaun, There is a rib along the inside centre of the track that should rest in a groove along the drive and idler wheels. Then it is a simple matter of ensuring the correct tension. What mechanical set up are you uisng and how many idler wheels?

am not sure how to set the idler wheels up so that they can take the correct tension without bending. am guna use 3 idlers.

Shaun, as you are not using our recommended wheels as idlers, it is hard for us to advise. We would recommend using axles of at least 3mm diameter and to have the idlers mounted close to the axle bearings.
