Four gear ratio options cover the race-spec spread - tight ratios for criterium and rolling terrain (11-25, 14-28), through general road (11-28) to mixed terrain (11-30). The 14-28 variant in particular gives tighter sprocket-to-sprocket spacing than the more common 11-28, keeping the rider in their optimal cadence range during sustained efforts.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eConstruction \u0026amp; Materials\u003c\/strong\u003e\u003cbr\u003e\nUltegra-grade construction delivers a weight saving over the 105 HG700 while retaining the same Hyperglide+ shifting performance.
