race and freestyle brakes and seatpost

[al-bmx]

just an observation but why do race bikes have a 27.2mm and freestyle a 25.4mm?

also why dont race bikes use U brakes instead of V brakes

[bobbbbsy]

GOOD QUESTION. BETTER CHOICE OF ALLY SEATPOSTS FOR 27.2 ?! DUNNO

 V BRAKES ARE THE WORK OF SATAN !

i agree they look so clumsy i much prefer a U brake under the seat stay

[bobbbbsy]

they look crap on any type of bike !

V brakes work a lot better than U brakes.

Seat tube? not really sure, could be something to do with material wall thickness v weight v strength.

Any way, get a custom made, that way you can have what you want

...and chrome rims are very crap in the wet.

V-brakes are quite quick to open up if you needed to change a tyre or mess with the gearing, not sure if U brakes are as quick and convenient.

[oldtired]

if you get u brakes that use knarps rather than fixed bolts for the straddle cable then they release as quick as v brakes for wheel swapping etc  as Bren says v brakes work better

Nice bike Bren by the way ,  not seen that one before , defo an old pic you can see the first berm if it were a recent pic it'd be behind the "JUMP OF DOOM"
