    Chain recommendation for a heftier rider?

    I'm coming to the conclusion that my chain is stretched - haven't really checked it, but the tell-tale signs are there - slippage when shifting, coupled with the fact that I've been doing a lot of hills, I'm around 250 lbs (started riding last year at 325) and have put more than 100 miles on the bike in just the last three weeks - only have about 200 miles total on the bike since I bought it new last year.

    So - rather than waiting til the end of the season, I'm going to need to have the chain replaced this week before other things start to deteriorate, and wondering if there's a certain brand that tends to be stronger for folks who will be putting the chain to hard use?

    I have a 21-speed, run-of-the-mill Raleigh Passage 3.0.

    Chains don't really "stretch" in the way you are thinking; the force applied by (even a large) person pedaling isn't enough to do that. They generally get longer because the bushings in the chain wear resulting in the overall chain length increasing. Properly lubed chains usually last much more than 200 miles. It may be that you have another problem, possibly your derailleur needs adjustment.

    If you do decide to put on a new chain though I have found the SRAM PC 68 to be a pretty tough chain for 6/7/8 speed use.

    Er 200miles = brand new chain. Unless someone sold you a worn chain. Measure it and report the results.

    Yeah, I'd guess the symptoms point to other problems, like derailleur misadjustment and cable stretch. Possibly wheel misalignment. Of course, you can easily figure out which is the culprit by measuring the chain.

    I weigh 350+ and had 3,000 miles on a chain before I replaced it.

    The same chains used on other bikes are used on tandems (only more links), so weight isn't going to wear a chain that fast.

    Are you easing the pressure of the pedals when you are shifting?
