|   down tube dent on scandium frame | rough rider
Aug 9, 2002 1:46 PM | | messed up riding over a wood cyclocross style barrier last night, dented my Easton thin wall scandium down tube. Actually more like flattened a section of the tube 4cm (1 1/2") long, 2cm (3/4") wide, and about 0.3cm (1/8") deep.
How much have I compromised the strenght of the frame? |

Aug 9, 2002 4:05 PM | | Not sure in your case but I recently got two pretty decent dings in the tubes of my light Giant XTC aluminum frame by tossing the bikr around in a mild burst of anger.
Anyway an LBS advised I could likely get quite a while (a few years)
out of it yet since the dents were relatively minor and did not occur near any joins. He did state however that that was his experience--but that each bike is different--it could actually go tomorrow. Who knows.
Have a reputable wrench check it. Not any LBS--esp where you bought it if it is not a warranty issue--they'll be wanting to sell you a new frame whether they feel it's really neccessary or not. |

Aug 9, 2002 4:07 PM | | Not that much, IMO. The down tube is primarily a tension member (think about Slingshot bikes, with a wire for a down "tube"). Tension capacity is dependent on cross-sectional area, which you haven't changed. If you're running a 5" fork, then some compression of the downtube is occurring on big hits, but the primary force on the downtube is pure tension.
I bought a frame recently off the Marketplace knowing it had a dented down tube. I discussed it with the local rep, who agreed with me that it's no major concern. I beat on it like any other bike and have no real concern with it.
Resale value, however, is another story... |
