Hello everyone. I just purchased a set of single speed (freewheel type on sram, shimano freehub) fatbike wheels that are disc brake ready. I want to purchase a kit to try and run both the brake rotor and engine drive sprocket on the same (left) side. Anybody have any input? Tips? My wheels rim width will be 100mm wide. Im running a smaller tire so 100 mm is the clearance. Im kind of wondering if any of you succeeded in this (the sprocket disc part. Im running a 44 tooth rear drive sprocket and wonder how whoever is doing this is fitting their caliper between the sprocket and rotor. Do calipers fit in between sometimes without buying a much larger rotor? Or do all need be small drive sprockets with large rotor to solve that problem? Is it better to just do the jackshaft brake mid bike and forget the rear brake? ( I have a Gasbike jackshaft billet plate) so thats a great option too. Ive seen that mod and wonder how it stops? Is it good? I will have a really nice big rotor on the front so Im not too worried about it being on the rear. As long as I can stop nicely. Im only running a 79cc Harbor freight predator Which disc/sprockets kits are the best? I already know I have to buy a new sprocket So far these the vendors I found: *Kings sales and service *Jakes motorbikes *Bicycle designer *Miscelaneous items on ebay. (somebody is selling 1 piece recessed sprockets that mount to thehub) I think their from europe. Dont know if a disc rotor will be turn key with this one Just looking for some tips and feedback so I can sort these thoughts all out. Is it more reliable to just do the jackshaft brake mod and leave the back hub strictly for the drive sprocket? Some feedback from those people who have that direct bolt on sprocket to 6 hole hub is appreciated. How are all your direct 6 hole sprocket to hub direct mounts holding up?
