I am still having issues with the chain randomly dropping off the front chainring towards the inside. It never happens during shifting and usually in a mid gear but I have set the derailleur limit screws anyway. Would shortening the chain increase the chain tension and maybe prevent this from happening? If so, how many links should I remove?
Below please find the actual simple equation calculation; according to the specified Part Tools simple proper chain length equation using their stated and specified equation as followed and specified using CCS specific data known input parameter information:
Simple Equation: L = 2 (C) + (F/4 + R/4 + 1)
L equals 2 x 17.5inches plus (52/4 plus 32/4 plus 1)
L equals 35 plus (13 plus 8 plus 1)
L equals 35 plus (22) equals 57 inches
L equals 57 inches
L equals 57 inches for the actual proper total calculated chain length using equation above
---------------------------
L = Chain length in inches. Round the final result to closest whole inch figure.
C = Chain stay length in inches, measure to closest 1/8". 445mm equals 17.52 inches calculated; rounded off to closest 1/8 inch equals 17.50 inches.
F=Front Chainring teeth
R=Rear largest cog teeth
Fractional conversion to decimal for 1/8" measurements:
1/8” = 0.125”
1/4” = 0.25”
3/8” = 0.375”
1/2” = 0.5”
5/8” = 0.625”
3/4” = 0.75”
7/8” = 0.875”
Use chart above to find decimal measurement.
F= 52Teeth Number of teeth on largest front chainring.
R= 32Teeth Number of teeth on largest rear cog.
The bicycle chain for the CCS should not be any longer and/or shorter than 75 inches.
The good news is all is not lost however if one has set the chain length to exactly 57 inches and the bicycle chain still does not stay on the front chain ring properly; simply just tilt the entire rear wheel axle and rear wheel that is held between the rear spreadable bicycle chain stays(sight directly down the parallel rear frame chainstays) ; with the rear wheel axle/ wheel slightly canted and tilted to the right side, that should help the bicycle chain stay on the front chain ring; this will help serve to counteract the former pulling tension forces to the inside(left) side of the chain ring; by now pulling instead now slightly to the right side by re-positioning the rear wheel canted and tilted at the axles slightly to the right side between the rear chain stay dropouts one can hopefully realign the rear wheel and its associated rear cogset to be in better perfect rear cog gear alignment with the front chain ring alignment.
Juiced Bikes has probably cut the length of the chain correctly for their CC bike; so its more likely that its a common issue with the misalignment of the rear cogs with the front chain ring; which also happens quite frequently also as well in the bike assembly process;
also make sure your high and low limit rear derailleur screws are adjusted properly so as to hit their high and low limit parameters; check to make sure that the "B" limit screw on ones Shimano Alivio rear derailleur is also adjusted properly also as well; the jockey pulley wheel should be between 2-3mm away from the largest gear cog on ones rear freewheel and/or rear cassette to help ensure smooth, reliable and crisp shifting.
