Sprocket change/ chain length

[K Wolf]

Is there a formula to determine how many chain links are needed when sprocket size is changed?

 

[runeight]

yeah!..glad you asked that question. I want to go from a 42 rear to a 40.

2 teeth down 2 links out. Unless you have the room to move the rear tire back.

and is it possible to remove two (2) links with the chain still on the bike? Rear wheel removed of course.

Sure how good are you with a die-grinder.

Late reply. Also could use an Dremel. Master links come 2 ways. The clip type and rivet. I recommend the rivet. Tools can be bought or borrowed. Several rivet tools. Ranging in price for I think about 20 all the way up to ? 150. Got a good one from pitposse on ebay for about 40 or 50.

nah..gives me an excuse to put a new gold chain on it.

Oh..I counted the links..112 without the master link...soooo..that should be 110 link chain huh?

two down in the front what will that do for you

 

[06BUSA]

Sound right.
Still gonna need a master link. Most chains are coming with the rivet type. Dont forget to get your hands on that rivet press.
Gold huh.

He was talking 2 down on the rear sproket. More top speed. Not sure, but torque should change. Prob a little less.

 

[06BUSA]

Down 2 in the front is huge. I wont mess with that one.
Sorry sure there is a pro who knows.

2 down in the front is not adviseable. The chain has to turn too hard to go around the sprocket causing all kinds of not good karma. Going Down i the front is the same as going up three on the rear as far as gear ratio is concerned. The smaller the front sprocket ( OR the larger the rear sprocket ) the faster out of the hole you can be. BUT your top end suffers. The taller the front ( More teeth ) and the smaller the rear the closer you get to a 1:1 ratio witht the tranny and the faster you can go top end. At least that's what i read in Cycle world once
