27,2 er den gamle standarden, og finnes i bøtter og spann.

hvis 27.2 er ukurant, hva er da de vi sleit med på 90-tallet... http://www.bikepro.com/products/seatposts/syncros.shtml Syncros takes an interesting approach in merely machining basic aluminum tubing, billet stock, and extrusions to derive a highly adjustable and superior seatpost. The Syncros clamp system uses two bolts to hold down the upper clamp piece which also cinches the lower clamp piece and the saddle in placethat. The two bolt tie-down system is becoming popular. The upper clamp piece is made by machining 2" by 2" piece of extruded aluminum. The extrusion is about 1/2" thick with a 7/10ths by 3/10th hollow running through it. Excess areas surrounding the hollow are cut away to make an arm on each side with a slot milled through them so they become two .2" wide arms separated by a .21" groove between them at the center of each side. A hole is drilled through the arms that will accommodate a brass rod. The rod is .58" long and .3" in diameter with a hole drilled through the middle of its side, tapped with threads. These rods on each side will anchor the bolt that rises from the head piece to hold the clamps in place. Added holes are drilled through bottom to top to reduce the weight of the piece to its 36.5 grams. The lower clamp piece is again extruded in a half-round shape with a hollow center. On the top a groove is milled for the 7mm saddle rails leaving 1.1" of contact. Added milling is performed to the top to reduce the pieces' weight to just 18.5 grams. The head piece is machined from billet aluminum. An inverted hemispherical top makes the cradle for the clamp pieces to lie and be restrained against. At each end of the head piece is a protrusion with a slightly oblong hole drilled for the tie-down bolt. The hole has a cupped perimeter on the lower side to accommodate a sintered brass washer which relieves some of the friction in tightening the bolts upward into the brass anchors. The bolts are made of cadmium plated steel with 5mm x 1mm threads, are 35mm long have a 4mm hex fitting and weigh 6 grams each. The head piece is a mechanically simple work of amazingly intricate machining. The seat mast tubing is made from 7075-T78 aluminum tubing, with the head piece pressed and bonded in it to a depth of 1 inch. The weight of a 26.6mm Syncros Hardcore 330 post is 222 grams. The Syncros 330 post is made in Canada, and available in 26.0mm, 26.2mm, 26.4mm, 26.6mm, 26.8mm, 27.0mm, 27.2mm and 27.4mm It is also available in oversize dimensions - 28.0mm, 28.2mm, 28.4mm, 28.6mm, 29.2mm, 29.4mm, 29.6mm, 29.8mm, 30.0mm, 30.2mm, 30.4mm, 30.6mm, 30.8mm, 31.0mm, 31.2mm, 31.4mm, 31.6mm, and 31.8mm for $10 more. Made using Black anodized tubing with Silver clamp pieces.

Ramma er nok lettere ukurant med litt lav ræv ja. Så da må det ukurant setepinne til.
Har kanskje ukurante dimensjoner på kroppen da 410-pinne er akkurat langt nok på medium Chameleon.
