it states there in the yss page that the x series comes in different lengths. 205, 215, 235, 240, 250, 255, 260, 265, 270, 280, 290, 300, 310, 320, 330, 340, 350 and 360 mm. so im wonderin, can i get one in a different length other than the 205 which is for our bikes? im kinda heavy, weighing on ard 100 on the scale, so when i sit on my bike now with my yss o series, it kinda drops, all i can do is set it to the highest click. im wonderin whether i can get one ard the length of 235? is it possible? anyone any ideas?
