X-PR prices are manufacturer MSRP and were verified 2026-06-08; confirm current pricing on quintanarootri.com before each campaign. A2 SP prices are current direct prices. Rows above the divider match the same groupset on both bikes; the “entry electronic shifting” row compares the closest electronic-shifting builds across brands (SRAM Rival AXS vs Shimano 105 Di2), which are different groupsets at a similar tier. Wheels: the SP ships carbon wheels standard on its Rival, Force, and RED builds (the 105 build ships aluminum); the X-PR ships an aluminum Vision Team 30 wheelset standard on every build, with carbon available as a paid upgrade. Rows marked “not offered” have no equivalent build.

Or buy it pre-tax
Eligible buyers can use HSA/FSA dollars through Truemed. Illustrative example: at a 30% effective tax rate, the $3,115 Shimano 105 SP could mean about $935 in pre-tax savings — an effective net of roughly $2,180. Your actual savings depend on your tax situation and Truemed eligibility.
Why riders choose A2
Carbon wheels, lower price
On the SP's electronic builds (Rival AXS and up), carbon wheels come standard. Comparable X-PR builds ship aluminum, with carbon as a paid upgrade — so the SP can cost less and still roll on carbon.
