TUNE STARKES STUCK

£119 - £130 (scroll down to configure this product)
The Starkes Stück Seatpost tube is CNC machined from seamless drawn 7075 heat-treated aluminium. A unique multi-butted extrusion, not only unique to Tune, but unique to each Seatpost diameter to guarantee the optimum balance of lightweight and strength is all sizes. Lighter than most carbon tubes, yet no chance of compression damaged through clamping.
This beautifully machined tube is paired with a 7075 aluminium Arbor & Craw system (the clamping beam through the post and beams above the rails), which clamp the saddle rail into a carbon cradle using TiA64V titanium bolts featuring cold-rolled fine threads and radius machined heads for perfect alignment and micro-adjustment.
The front & rear bolt arrangement allows for very fine saddle angle adjustment, and zero possibility for the saddle to slip. The Arbor is slightly longer than required, allowing a little fore-and-aft movement to compensate for extreme seatpost angles.
Available in two diameters, two lengths and the full range of Tune anodized colours.
