i agree with 1fitz depends on the chainstay. i have the ascend moher hunting bike from cabelas and outfitted it with the bbshd and my chainstay will only allow me to fit a 34 tooth chainring. i currently have the mighty miny 30 tooth chainring on and have incredible climbing power my rear cassette is a 10 speed 11-48 . my top speed is about 34 mph on a flat with tires ( 4.9 inch ) filled to 20 psi. very bumpy ride. in addition i had to have the chainstay notched and modified to fit the bbshd. not recomended to do unless you are or know a professional welder with frame building experience. to sum it up the bigger your chainring is the less hill climbing power you have but gain speed, hope this helped
hi sorry for the late response , but i dont check my e mails that often as you can see lol, so lets get right into it. by now if you tried to outfit the bike with the bbshd from bafang tnen you ran into a clearance problem with chainstay and if you tried to use spacers to correct the problem then your chainline is way off . the way i had to correct the problem was to notch the cnainstay and reinforce the chainstay with filling and welding ,a friend with frame building and welding experience. helped me with it otherwise i would not recomend doing this unless you know how or have help doing so . in addition i added front susspension forks to the bike from wren sports, i ordered the tapered style fork because the headset is tapered only to find out that when i removed my original forks the steer tube was straight and could not use my original crown race ,after an exhaustof serch for the crown race i needed to match my bearing cage and and tapered fork .realized that i had to get my original crownrace machiened to fit my forks,again thanks to friends.hope this helped if i was not to late lol. check out the cool 3200 lumen dual headlight from fisher fabhouse i added to my build. any questions please feel free to ask i will try my best to mind my e mails lol. bye for now RSP
depends on the bike and the chainstay , u might need 36t which has low offset 5mm or 42t has about 18mm offset (chainline more toward the wheel). for a fat bike id lean toward 36T HD ring, also better torque for climbing on a heavier bike.
