help with nimbus T bar!

does this bar fit on the 09 seat post and seat? the adjustable seat mechanism seems to be too wide, am i doing something wrong?

The 09 seatpost is made in 2 versions if i’am correct,

If you have the adjustable seatpost with 4 holes that will fit any standard unicycle seat, you then can not use it without modification on a t7 bar.

The t7 bar is made for use with a bicycle seatpost.

If you want to use the kh adjustable seatpost you have to remove some material to make it fit the t7 bar.

best solution go to your local bicycle store and buy a seatpost:o
