My team is thinking of buying flex wheels for this year’s Spin Up Season. We are new to flex wheels and are seeking some advice on how they work and which ones we should buy. We have also heard that there are a couple of different parts that you need to buy in order for Flex wheels to be compatible …

the 60a, 30a and 45a signify the harness of the plastic on the durometer scale. the 2inch and 1.65inch flex wheels are also skinnier. the versa hubs go inside the flex wheels then you slide a hex adapter pice in and then you can put in the hs shaft or put in another adapter for the ls shaft

Ok, thanks for the explanation. Could you elaborate more on what the durometer scale means in the case of flex wheels? Do 60A, 30A, and 45A directly correspond to the relative harnesses? Which number do you think would be ideal for a Spin Up flywheel and which for an intake? Also, VEX listed many Ve…

[image] For the intake I would suggest 30a and for the flywheel it is all up to personal preferences.

[image] these for the 1.65in and 2inch [image] these for 3inch + for these you still need the hex adapters

Yep, 30A is the softest compound, therefore making it the most “squishy.” 60A is a lot firmer, and therefore it has less compression. Versahubs are the most convenient way to mount the 3” and 4” flex wheels. Versahex adapters are the most convenient way to mount the 1.625” and 2” flex wheels. Sid…

Thanks for all the resources! They should help us a lot. How would we get the VersaHex adapters? Aren’t they discontinued?

I don’t know if they are discontinued but if you can’t get your hands on them this thread is about using alternate methods to mount flex wheels [image] Better Ways to Mount Flex Wheels Technical Discussion Flex wheels are really good stuff, the compression and the friction…

A company called West Coast Products also sells the VersaHubs, flex wheels, and other accessories. You can order it from them just make sure the part number is the same as the one on VEXs website.

Ok. West Coast Products also sells 5" Flex Wheels. These aren’t listed on the VEX website, and the maximum size there seems to be 4". Does this mean the 5" flex wheels are illegal or just discontinued? What is the maximum flex wheel size that y’all have used?

5" flex wheels are not legal for use in vrc since they’re not listed as VRC legal on the vex robotics product page. The only legal flex wheel sizes are 1.625", 2", 3" and 4".
