The Zipp SL-70 Ergo is built around two geometry choices that work together. A short 70mm reach keeps brake levers within easy range without sacrificing steering leverage, and a variable-radius drop opens up multiple hand positions as the hours stack up. The 10-degree ramp angle transitions cleanly to modern shifter hoods, and housing runs along the underside of the bar to keep the front end clean without adding routing complexity. What Our Gearhead(R) Experts Are Saying:"The 70mm reach puts the brake levers closer than most bars, which means less stretch on a long day and more control when the road gets rough."
