WORD OF CAUTION!

 

TEST RIDING FOR STRAIGHT

I absolutely do not recommend that anyone try this test to determine if a bicycle frame set is straight or not.  However, I use this method every time I test a bicycle's geometric integrity.  The test is very dangerous and probably against the law.  It also works but as I have found out in one particular instance, not every time!  With that qualification out of the way, this is how I "test ride for straight".

After carefully checking a bicycle over to ensure that it is safe to ride, I test ride it for a short distance.  When I go for the test ride, I begin by getting the bicycle up to speed.  This does not mean go fast, just go fast enough to ensure good balance.  Once I have achieved this state, I slowly begin to relax my grip on the handlebars.

Relaxing my grip on the bars does not mean that I throw my hands above my head in a "Tour de France" victory gesture as I cross an imaginary finish line.  It means that slowly and almost one finger at a time, I relax my grip on the bars.  If there is a geometric irregularity, the bicycle will begin to pull one way or the other.  The tendency to pull will be felt immediately and perhaps very strongly.  I am extremely careful when using this method of testing a bicycle.  If you feel this act pulling action beginning, try to develop an understanding of which way the bicycle is pulling. If I do feel the bicycle pull, I stop riding and get off of the bike.  It is time to investigate the geometric integrity of the frame set and, perhaps, make a repair or two.

If I do not feel that the bike wants to pull one way or the other, I continue to relax my grip on the bars until I am not touching them at all.  If the bike can be ridden with no hands and still tracks well, all is likely well with the frame and fork set.  That said, this is no guarantee that all is well.  A frame and fork set can be bent in ways that counter each other allowing for hands off control, as was the case with the blue Mercier.
