Impressive speeds! One thing i find hard to beleive is "Which speed is right" ... for example, i've tested my speed using: GPS, Bike speedo, and the "Your speed is" road sign .. all say different things!!
Speedo: Hops erratically between 10 and 50 (somethings really wrong with it)
Speed sign: 32
So personally i'm sceptical of bike speedos, the electro magnetic intereference that the bike creates can often trick the speedo into crazy stuff ..
So is GPS the most accurate? providing youre doing a constant speed for an amount of time on a straight road?
dangit, i hit 41.8 mph the otherday on my schwinn heavy duti with an andyinchville 34t sprocket, bgf 70cc, grubee pooo-poo pipe, and a deep tuck, and i thought i was going really fast, and then you guys come along with 50+, thanks!
