A2 Warehouse Sale  /  Final unit

One bike left.
This one.

The last SP in the warehouse is a size XL in matte black — never ridden, never registered, and it qualifies for the free Zipp 303 S carbon wheel upgrade. That makes it almost identical to the SP Rival AXS we sell new for $4,999. The only real difference is the saddle.

Why this one is different

The carbon wheel upgrade applies to this one.

The free Zipp 303 S carbon wheelset upgrade on current SP Rival AXS orders carries over to this Warehouse Find — so it rolls on the same wheels as the $4,999 new build, at the warehouse price. The only meaningful difference: the new build ships with the Bi-Saddle Hurricane, and this one has the WTB saddle from its original production run.

It’s an XL. Let’s make sure you fit before you buy.

Warehouse Finds are not eligible for returns, exchanges, or size swaps — so spend two minutes with the fit calculator before you commit. It takes your measurements and tells you whether an XL is right for you.

The good news: the SP has over 250mm of fit adjustability across the cockpit and saddle, so an XL dials in across a wider range of riders than a typical XL would. If the calculator puts you anywhere near the line, talk to us first and we’ll tell you straight.

Why A2
