woops..for some reason i couldn't post messaegs so tried this test one..oi..
hi all.. well, i know how to measure my contact points and hvae that down pat. but recently it's become quite clear to me my stock steel torelli super strada is my favourite bike. now i'm kinda scared that if i ever crash it i won't be able to replace it, so i'm trying to measure the bike. i need tips to get this accurate.
in particular, i am having a hard time measuring the below:
top tube: i put the measuring tape on the center line of the top tube, from the center of the head tube to the center of the seat tube. this yields about a 58cm, maybe 58.5cm.
head tube: with the headset in, it measures from end to end approximately 20.4cm. i guess the proper way to measure this is without the headsets. since i have shimano 600 headsets i can measure up to where it curves out to vertical (those of u with 600s would know what i mean), which yields about 21.1cm.
chainstay length: i measure this from the middle of the bottom bracket where the spindle is (not from the outside of the crank, but i put the tape on the spindle itself) to the middle of the axle. this yields 40.5cm.
so here's why i don'ot think i'm doing it right. (1) it seems i have a 58cm top tube with a big *** headtube that's more proper for a 60/61/62cm bike. i know my head tube on my stock 58cm serotta is much smaller, around 17cm. (2) my chainstays are just 40.5cm, yet every bike geometry i look up says a 58cm or bigger bike has at least 41cm chainstays. not to mention, this bike is also my most comfortable.
does this make sense? anyone know waht the torelli super strada geometries are? they're nto made any more and not on website... i e-mailed them, hopefully i get a response..
anything woudl be appreciated.
