Just bought some wheels which are 20 x 1 3/8. They look a bit skinny to me.

Are these normal size for a race bike ?

Would 20 x 1.75 tyres fit ?

zed4130:
nope they are wheels for a junior bmx  :daumenhoch:

digitaltransfer:
You need to get 1 3/8 tubes they are for the smaller rider in a nutshell and a guide is as follows

1 1/8's mini micros etc..
1 3/8's Juniors
1.5 Expert
1.75 Seniors and Pros !!

Hope this helps

Regards  :LolLolLolLol:
