Team 237 uses a combination of 35 and 25 chain on our drive system. 35 chain from the transmission to the center driving wheel, and then 25 chain to both the front and back wheels. Just make sure your chains are straight, mostly protected, and tightened, and you will be good.

As for the ways to tighten, you do not have to make your chains the perfect size, as the season goes on, the chains can stretch, and only create problems. On 237, we make the chains have a little slack and we make a simple chain tensioner. This is made out of a 3/4" round piece of round delrin plastic, and drill a hole that is offset from the center. This is helicoiled for a 1/4-20 screw and set in line with the top of the chain in the drive system. Since it is offset, the piece can be rotated into the chain, and the chain will tighten and ride the delrin. This allows for an easy tightening at competition and easy maintenance when you have to change wheels and such. If you need pictures of this, PM me and I will be happy to help you.

In the past 2 years, we have never broken a chain, and only have lost 2 master links due to freak occurrences with a foreign object
