About 5 years ago, I bought a Specialized Sirrus Sport--the $600 version of their "multi-use" bike. Aluminum body and fork.
I may have put on, I'd guess, 3,000 miles over the last 5 years. It's the "Large" version of the bike for my 6'2", 185 pound body. I generally ride around city trails, and often have to ride over curbs. I ride it moderately hard, although I've never broken a chain.
Over the last month, both the front and back wheels have gotten screwed up--the front wheel got noticeably out of true for no reason (other than the fore-mentioned curbs), and a spoke on the back wheel broke for no reason. I've made repairs to both of those things.
I'm planning on going on a 350 mile bicycle tour this fall. The same type of riding I do around town, but with an extra, say, 30 pounds of gear on the bike, plus further away from repair resources.
In a thread under the wheels and hubs forum, I've been advised to build some new 48-spoke wheels with quality parts, for a cost about $300 total. I also need some new tires, which brings the cost of the overhaul to $400 (you can now see where I'm going with this).
When I'm really pushing up a hill or whatever and am pushing down the right peddle, the bike makes a certain squeak near the bottom bracket. It could be the peddles, cleats, crankshaft, or possibly the frame. It's that last point I'm worried about. The owner manual says frames do wear out and that squeaks are a tell-tale sign. I'm wondering if I've worn out the wheels if I've also worn out the frame. And in general, can a 5-year old aluminum $600 bike with a somewhat larger than average rider handle the strains of a modest tour?
I could probably afford to upgrade to a real touring bike, but I don't feel an overwhelming need to do so. Any thoughts on how much life is left in my bike and whether it can reliably handle the strain I'm putting it under?
