Maxxis Dissector II Tire. Dual compound, Exo, Mounted on the rear of a 160/145 trail-enduro bike. Noticeably better braking and cornering than the old version on dry hard /loose on hard. Good rolling. I will be trying a Dissector ll MaxxTerra, Exo+ on the front

Great customer support and great prices

They had a sale going on and I was looking for a replacement chain from X01 sram eagle axs it was a great price. It was a problem with with shipping who had nothing to do with the seller they quickly expedited a new chain for me. I really appreciate what the customer support they have. I’ve bought many items from them and I will continue to support them.

Worked perfect for my 1/1 hub bearings.

I used this for my 1/1 hub 15307 bearings and it fit perfectly. I can see this tool being useful for other bearing jobs as well. Worth getting if you're a DIY'er.
