NOpe that photo is with a Speedway rear ( i have 19' - WM3 rims so tyre are limited - rears are quick change hubs ) but i have also had good reports on the kenda carlsblad.
It depends on the bike, most of my Flat track bikes still have the round US rubber on them in the early MT carliles and also later FT goodyear or maxxis block patterns, only cause they look right on the bike, it would look silly with a skinny pulled over it, downside is they run like shit on our tracks, but im after a look rather than a place these days.
on the mx BIkes i also run at Dt, i use the thin knobbly like the kenda sticky and they are much better handling and steering ( bit like a speedway front) you wont get a beeter tyre up there for crushed granite tracks
I have been using the speedway rears as front and rears as i picked up a dozen or so for Nothing at the last aussie titles here, so not only do they fit but they where at the right price.
Thats the only Flat tracker i have with the TX front the others are spools but you cant really tell the differance and they look fatter too, the spoolers might save you weight but you wont notice it and if you needing that kind of advantage then you really should be using a small hub front brake like out of a 100cc somthing as you need front brake if you not on a oval track.
IF in you want to lace in a spooler for resto looking then you can get 36 holers out of the State for under $150 but if your getting them off ebay second hand then just check you not buying a 40 hole as many where in the early chopper type one. I have some contact in the US if you really want to go down that path but if you are then youll want to run a fat rim or the look is lost.
What are you trying to achieve ? and what bike is it for ?
