[inopinatus]

For this build I acquired (from eBay) a bargain-basement second-hand test saddle of the same model I use in competition. Well, it was the alloy-rail version rather than the carbon-rail version, but otherwise identical in form. My butt was happy with it, which is what matters.

Can confirm it was still the single most expensive component of the whole bike build, more than the frame, wheels, or groupset even.

Test saddles aren't supposed to be sold to the public; I believe it was a liquidation sale.
