smaller chainring - chain trimming question(4 posts)

smaller chainring - chain trimming questionwolfereeno

One more Q for you wizards.

I ordered a couple of smaller front chainrings to mess around with for my new Pista. A 44 and 40 (currently running 48x16).

Once I trim the chain to fit the smaller gear, can I add the links back if I go back to the larger gear? Do I need a special pin like my Shimano 9 speed group chain does?

The Pista's chain's listed as "KMC 1/2x3/32"

Is it common to add/remove links as one messes with the gears or is there a point where you're better off starting over with a new chain?

Thanks very much for all the help.

BTW, I rode today in the sleet on a totally flat path and the 48x16 was fun. But the hills are a bit of a grind. Can't wait to try the smaller gears in a day or two.

I'n the track chains, especially, I have found no problems in adding back links. Just did it again last night.

The stock gears on the Pista are pretty tall for hills.

I prefer changing cogs to rings. You get about 3x the movement in gear ratio for each tooth difference.

The ring was $15 and a good cog was morem plus I'd have to buy a lockring tool. Also, I don't have any extra links to lengthen the chain so I'd need to get a new chain too. Times are lean :-)

If you change rear cogs you usually don't need to fool with the chain as each one tooth change (chainring or cog) only moves the axle about 1/8" in the dropouts
