    Ok, maybe I'm just getting too tired, but I've been racking my brain trying to find a 10 tooth 5/8" bore sprocket that will be compatible with my bicycle chain rings. I searched and searched and then realized that they sell them at SBP but, and no offense to the guys at SBP as they have been very helpful, if I get charged the $10 shipping the price tag of nearly $30 is going to feel a bit steep for me. I emailed Pablo to see if I can even get a 10 tooth from him since it isn't actually listed as a sale item on the site.. I think he will as he sold me the freewheel crank setup which isn't listed either.
    As best as I can figure out, it is a #415 sprocket that I need..but I'm really not sure because I can't seem to find exacting specifications for #415 chains so I don't actually know if that is the same chain that is used on a mountain bike. I do know for sure however that the mountain bike chain has 3/32" roller width and a 1/2" pitch.

    Does anybody know where I can get a cheap and compatible sprocket from?

    Scroll down to #41 sprocket or... the TAV Replacement Sprocket.

    Looks like they have 8 to 17 tooth.
    Ive ordered from them many times with no problems. Tons of other parts also.

    Sprocket for #41 chain. Has 5/8" ID.
    Choice of 8T-14T, 17T
    8T Sprocket has 3/16" key broached into the hub rather than a keyway, so no key is needed.
    9T-14T & 17T Sprockets have 3/16" keyway. Both have dual set screws.
    Part # 400901-**

    SKU Number:400901-**

    Price: $9.50

    As I stated in my email, shipping won't be $10 probably $5.

    However, we don't have spare 10T's laying around. They are all in kits (sub-kitted within the kit) and we are once again running low on kits. We do have 9T and 11T in stock and ready to ship.

    A #41 sprocket will not work.

    Thanks for the reply, but a #41 chain has 1/4" thick rollers as opposed to the 3/32" rollers on my bike chain. Are you sure the sprocket will work? I cuerrently have a 10 tooth #40 sprocket and it is WAY too big.

    Just noticed the last portion of your reply that states that a #41 wont work. I didn't think it would either. Thanks for the break on the shipping, I really wanted a 10 tooth since that will keep me exactly within my target speed range but if worse comes to worse I could change the output driver on my engine to a 7 tooth and then go with a 9 tooth from you guys.

    ...I don't suppose there is any way I could pre-order one for your next shipment? I probably wont want to though because I don't think I will want to wait much longer. I'll let you know shortly, Thanks again!
