My 1996 Trek 750 Multitrack has been a very good bike (I bought it new). I have ridden it off and on as a commuter but didn't take the time to replace the chain until this year with an SRAM (originally had a Shimano IG).

Soon after, I started experiencing chain skipping (I understand that this is because of wear on the sprockets). I brought it in for a tune about 3 weeks ago (new cables, truing, adjustments). In the last week or so, it's begun skipping alot. I don't want to buy new if I don't have to because I'm content with the bike.

So is it worth trying a different chain before I start shopping? I ride about 4.5 mi. each way every day. I've been considering an internal-gear setup for low maintenance, but I'm not sure 7 gears would cut it. I usually stay seated while I ride and must use the lowest front gear on one steep portion of the ride.

Thanks for any opinions/ideas.
