I bought one of those near my Seattle residence after I got a free bike from another Subaru driver. It needed a chain, rear shifter and cable, and just last month when I was out there again it had a completely flat tire. The tire was glued to the wheel with something. I thought bike tires held themselves on like car tires. Basically, not really worth fixing for a [secondhand] cheap ebay bike.By the way... I purchased a Park Tool MLP-1 master chain link breaker and it is the most wonderful tool ever. $12 well spent.
A couple of fairly steep, but short ones near the Northern access. Those were the "worst". there was a lady with her young un in a trailer, that passed us! If a woman can do it, you MIGHT be able to. >;-)That's a beautiful area... how were the hills? I've been looking for a place to go ride with the kids (in a trailer).
So it sounds like there's a story here... do tell!!
Mountain bike? 8 or 9 speed? I've always had good luck with the SRAM 970 cassettes. Not the cheapest, not the most expensive. For the chain, go with a SRAM PC951. That's assuming you're running 9 speed stuff. More expensive stuff = lighter = wears out faster. IMHO the 970 cassette & 951 chain are a good, durable combo.
Also check jensonusa.com as well as amazon.com. Jenson USA will price match anything but their free shipping is SLOOOOOOOOOOOOW.
And while yer at it... get a Park Tool MLP-1 Master Link Pliers... $11 on amazon. Makes removing the master link of a SRAM chain a piece of cake.
