I've included pictures of my three main bikes. The first one is a Trek 950 that I purchase new in Moorhead in the mid 90's for around $700. It has been solid. I wore out two geared drive trains, ran it as a single speed for a year to now have it as a 1x8. Perfect gearing for its use as a winter commuter. I lubed it up and tightened the rear hub; an adjustment after putting the freehub body in.
The next bike is a 2000 Diamondback XR4. I purchased this a NOS in 2002 for $1000, about $800 below list price since it was a held over two years. This has been a good bike with few problems. I'm, however, leaking some oil out of the front shock. I emailed Shockspital for a price quote and possible diagnosis. I also need the rear wheel trued and tensioned. I will not likely ride this bike again until next spring.
The final bike is my LHT that I purchased in Sept of this year. I cleaned up the drive train and relubed it. I'm very please with this bike thus far. I was fortunate enough to get this bike for cost, $690. It retails for $1,100.
All three of these bikes are mid-level bikes that have served me quite well. The 950 and XR4 have proven overtime to be quite dependable; I expect the LHT to do the same with good maintenance.
