Discussion Overview

The discussion revolves around a survey regarding the thickness of bike frames, specifically focusing on the dimensions relevant for attaching a bike alarm. Participants share their experiences and measurements of frame thicknesses and diameters.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant inquires about the thickness of bike frames for a survey related to a bike alarm.
  • Another participant provides specific measurements, indicating that their thick street bike frame has a wall thickness of .049 inches, while standard bikes may have a thickness of .035 inches or less.
  • A third participant clarifies that the original inquiry pertains to the outside tube diameters of the frame rather than wall thickness.
  • A later reply shares specific outside diameters for various tubes of their bike frame, including 1.5 inches for the top and down tubes, 1 inch for the seat tube, and 3/4 inch for the downtubes.

Areas of Agreement / Disagreement

Participants have differing interpretations of the original question regarding frame thickness versus outside diameters, indicating some confusion but no consensus on the primary focus of the inquiry.

Contextual Notes

There is a lack of clarity regarding the definitions of "thickness" and "diameter," which may affect the responses provided. Additionally, the discussion does not resolve the initial inquiry's intent.

hey, I am doing a survey for my bike alarm. How thick is the biggest frames on your bike, and how thick is the smallest frame? a reply would be very helpful. Thanks

Thick as in the metal inside a frame? On my bike, a very thick street bike (stunt/bmx whatever you want to call it), it is .049 throughout. And that is thick! The frame weighs more than 8lbs (for a 20in bike) I would say your standard bike is .035 or less throughout, probably less for a cheap mountain bike.
 
He's attaching an alarm to one of the tubes of your frame, Matt. He doesn't care what the wall thicknesses are. He needs to know what the outside tube diameters are.
 
lol, ok that's what I thought originally, but I thought that information was easy to get.
My frame:
top tube and down tube are 1.5"
seat tube is 1"
downtubes (rear triangle) 3/4"
