how do rim width's work,

20 x 1.75 = freestyle

20 x 1.5 = race

or is a 20  x 1.5 width for mini / jr ?

20 by 1.75 and 20 by 1.5 - the rims are 406mm

1.5's are generally for 'expert' sizes

the funky thing here is..

mini and junior rims 20 by 1.1/8 and 3/4 are actually 451mm

yes they are bigger, hense some times you cant even fit a 20 by 1.5 into a mini/junior, as you cant get to the caliper 'more over new school canti's

plus a sew up is some where in the middle, they have never been given a metric 'etktro' whatever it is sizing - but they do fit minis

beacause 406mm is actually 16 inches
a sew up is 17 inches - a whole inch closer


-hense a 1.5 is for a if yoike  'normal sized bike, but with a smaller top tube 'expert' - 13 year old
where you arn't too heavy, and use a 1.5 tyre instead of a 2.1

its confusing old school to new school, as mini's and juniors i think differ a bit

thanks steve,

the reason i asked is that i have some GT wheels 20 x 1.5 from the early 80's and didn't know what they were meant for !!

i used to have araya's 20 x 1.75 back then and moved onto skyways,

cheers,
rob :daumenhoch:
