Externally-butted seat tubes still have an internal butt at the bottom too, normally 28.6 .9/.6 with the bulge at the top being an integrated substitute for a sleeved collar
You may note that the actual ID is closer to 27.4 at the business end of the seat tube
well some things donāt matter
(i am prepared to be flamed)
we have decided that people can ride whatever saddle they wantā¦as long as itās not a brooks on a straight post
we are fairly equal opportunity on wheel sizeā¦as long as youāre not doing some sort of low trail 700c falsehood
uhā¦really stretching hereā¦we do not have super strong opinions on pedals except for those awful MKS ones that we hate, and also that crank brothers suckā¦ok take this one off the list, pedals totally matter
tried capturing a pros leg extension here. Obviously missed the bottom and some ankling going on but is it fair to say his seat is lower than others? Not saying itās wrong or right, just noticing that his legs donāt extend as much as mine and wondering what effects this has
