requires less clearance above seat tube vs the long-travel version
three elastomers included (light, medium, heavy)
Ordered directly from CaneCreek.
N.B. When this extra-extra-long post is used with the Xootr Swift, it is long enough to secure the bike in its folded position by touching the tire; the standard Thudbuster post isn't long enough for this.
I don't have an accurate way to measure the weight, but the Ø 27.2mm at XL length of 403mm is said to weigh 489g, so the Ø 33.9mm with a post-length of 507mm (total length 609mm) could be expected to weigh considerably more. I'd guess around 700g?
