Frame Material Trade-offs: 5 Years of Data from Daily Commuting & Weekend Tours

[Amy Liu]

As an all-season cyclist averaging 8,000km annually (50% urban commuting, 50% weekend tours),
I've systematically compared frame materials across weather conditions.
Here's my analysis combining real-world experience with lab-verified data:

1. Wet Weather Performance*
Weekly industrial zone commutes (with de-icing salt exposure):
- Steel: Developed rust under chainstay within 6 months (required bi-weekly oiling)
- Carbon Fiber: Clogged bottom bracket drainage caused internal moisture (85% RH sustained for 3 weeks per sensor data)
- Titanium: Only needed basic rinsing after 12 months (salt spray tests show 1/127th corrosion rate vs steel)

2. Vibration Damping
Smartphone gyroscope measurements on 30km asphalt/gravel mix:

| Material | Hand Peak Acceleration | Fatigue Index |
| Aluminum | 12.3m/s² | 82/100 |
| Carbon Fiber | 9.1m/s² | 67/100 |
| Titanium | 10.5m/s² | 71/100 |

3. 10-Year Cost Projection
Model based on Dutch Cycling Union maintenance data:
- Steel: Average 2.3 derailleur hanger replacements + 3 full repaints
- Carbon Fiber: Biennial X-ray inspections ($120/scan)
- Titanium: Regular headset bearing replacements only

Discussion Starter:
What's your most persistent material-related headache?
Coastal salt corrosion?
Tropical humidity damage?
Or desert sand abrasion?

huh... i guess i'll have to inform my 43 year old, never repainted, never had a hanger replaced, never vibrated bad enough to concern me, and never shown any signs of rust, Trek 930R that it's inferior to some dutch bike assembled with garbage components that weigh a freakin' ton.

PS.. i just rebuilt a dutch bike... the frame is aluminum... it now wears almost all japanese or chinese Second Hand parts, and is a vastly superior bike, right down to the Stainless Steel spokes, replacing the rusted junk ones it came with.

this is interesting data you have gathered, just curious why Steel isn't mentioned in the vibration dampening table, a lot of people have discussed how steel feels like a "magic carpet ride" compared to carbon and aluminum and ive seen many debated here about it. I've had experience with Steel, carbon and aluminum frames over a span of 7 years in very humid and tropical weather, in terms of persistent material headache I guess I haven't seen so much around except for the usual seizing of parts due to corrosion carried from sweat and the lack of grease or carbon paste present on the part that seized up. May I see your data?
