How Many Miles Has Your Bike(s)? Components?(5 posts)

Perhaps, it's just me. However, when I read some of the posts where people talk about fatigue and frame life I wonder how long they keep their bikes.

I have a carbon with about 20K and an Al with about 7K. They are 6 and 2 years old respectively. This does not seem very special to me.

I am not really concerned with nor do I believe the hype on frame life especially wrt Aluminum. I am sure manufacturers severely underestimate the life of their product - definitely a help in our overly letigious society.

Finally, if frame life is the arguement you use on your wife in order to rationalize your new purchase - that's okay. However, it's not really the feedback I am looking for.
Well in my experience it isn't the miles it is the other stuff.MB1

Crashing and travel damage are the only things that have ever destroyed any frame I have ever ridden.

I often ride a frame until it fails. The failure is always related to some damage that happened in a crash or while the bike was being shipped.
I asked a similar question last week, here's the thread....rtyszko

Too many variablesFez

Frames may last a very long time. Sometimes too long. Although plenty of frames break, a lot of them don't.

Here's some reasons why we stop riding a perfectly good frame:

1) Got tired of it. Upgrade fever.
2) Not worth putting a lot of money into it, or not possible to upgrade. Usually, not much sense in putting new wheels, bars, fork, DA group on a 10 year old frame. Sometimes, it just isn't possible. Rear spacing is an issue, and often times a different BB, headtube, front derailleur style, seat tube diameter, etc. makes an upgrade cost prohibitive. Lack of compatibility among 7-8-9 speed systems and STI shifters don't help either.

*******************

As far as longevity goes, there are too many variables.

I only ride 100-150 miles a week. My bike stays inside the house or inside the car at all times (except when ridden). I almost never ride in the rain. I weigh 150 lbs and probably don't have much power to fatigue the BB or headtube area. Oh, and by the way my frame is titanium. I think my bike is going to last quite a long time.

Contrast that with someone who is a lot more heavy and powerful. Rides 200+ miles per week. Races, crashes, rides in rain, puts bike on roof for transport, ships bike via UPS or airlines. Frame is scandium, aluminum, or carbon. That person's frame may have a shorter lifespan.

So basically, it really depends on the rider, the use (abuse), the frame material, and what and how much the bike goes thru. Frame longevity can vary from under 1,000 miles to over 20,000.

... but the bike has been in service for 31 years, probably has somewhere between 25000 and 30000 miles on the frame, has been BMXed, MTBed, neglected outdoors for years, and otherwise abused, bent, trued and the frame still strong and giving surperb service.

The tough sell was convincing the wife to let me have the flea-bitten old thing powdercoated for four times the price I paid for it new.
