    Does anybody know where I could find sprockets with more teeth than a 44t sprocket. I got some really big hills around where I'm at and it would be helpfull if I had a little bit more power!

    i didn't double check, but i believe dax has a 48th sprocket...

    Thanks alot! Dax does have them...How much will a 48th sprocket actually increase the climbing power? Is it worth the cost?

    in simple terms, the difference would come out about like the "difference" between 3rd and 2nd gear on a 5-spd cluster.

    someone who's owned the two can better answer this, i just felt like piping in :lol:

    I think you'll like the difference. I run a 50 tooth on my mountain bike.... never tested it on any big hills, but I pull a trailer for groceries/laundry etc. real good take off.
    will your bike pull you up your hills, even slowly or do you have to pedal too?
    I lived north of springfield when I was a I know about them Missouri hills.....and curves. here in kansas, everything is square & flat.

    My bike can get up most of our hills without needing to be assisted but it sounds sortof hard on the engine. Where did you get your 50th sprocket?

    You could also use a front chainring from a cruiser or BMX with an astrubula(1 piece) crank. You would have to drill mounting holes in the chainring to match your mounting system.

    the old grubee kits came with 2 sprockets, a 50 and a 44. I might have an extra 50 tooth. I'll look in the morning.

    You should be able to get a 50t sprocket from Mike at . I looked on his site but didn't see them, if you e-mail him or give him a call (# on his home page) I'm sure he can hook you up...Kelly

    Thanks a lot for all your help! I'm just curious, but is the 50th sprocket the biggest one out there?

    54 & 60 tooth sprockets

    here's a couple big ones. both would take some work to mount. maybe the 60 tooth could bolt to your existing sprocket? might mess up your chain alignment?
    60 about could prolly climb trees!!
    Wheelies?...... anybody?..... I know Tom wants to do some wheelies!!

    i think 50 is the biggest they go with out modding it to fit.

    oh you guys....and your need for speed! 8) I ride mostly in town & there's a lot of stop & go. I appreciate the extra take off ya get with bigger sprockets. I'd like to try a 60 tooth on my 55cc. it might only run 20mph but it'd get there quick. naaaa, cause then I'd wanna do some off-roading....& I don't heal up as quick as I used to.

    don't get me wrong here...i have the 44th and won't be changing it, i know i can get another 5-10mph but i just don't need it, no matter how bad i might want it 8)

    My kit came with a 44 and a 40 tooth. I installed the 44 and I'm not using the 40. I would be happy to trade my 40 for a 50 if anyone has one and would like to trade? :?

    50 tooth is too slow and not worth the increase in stump pulling up steep hills at the expense of top speed.

    A 48 tooth sprocket is your best bet. I live in Colorado at 7000 feet altitude. Every combustion engine (piston, jet, turbine) loses 3% horsepower for every 1000 foot increae in altitude. At my altitude, I'm losing 21% of the engine's power. I have found that a 48 tooth sprocket is all I need to climb even the steepest COLORADO hill with ease. I haven't found a hill yet that can't be tackled with a 48 tooth sprocket. A 50 is JUST TOO DARN slow for an 80cc engine that is slow revving to beign with.

    BTW, I have climbed mountains with my bike and my 48 tooth sprocket took me all the way up to 12,000 feet in altitude with no problem.

    I have some 55T sprockets I need to get posted on the website. Remind me to get them posted . Not sure of a price yet. I had them milled special on a water jet cutter. anyway..Remind me to get them posted.. Thanks...
  20. HI All,
    A friend of mine has a machine shop and can make ANY size sprocket for our bites (ready to bolt up using the standard 9 hole mounting plate). The sprockets are made out of heat treated 7075 T6 Aluminum for durability and is WAY lighter.....PM me if you are interested....He made me a 40 T sprocket with satin finish and lightening holes for $45.00 ( I tried the 36 T but it didn't pull hills well enough, and the 44 T was way too low a gear for me...I wanted a little speed too!)....
