I have seen the Dolomite Sprint gearset ratios frequently stated as 2.19, 1.57, 1.23, 1.00. I counted : 26,29,33,33 on the main shaft and 31,28,25,16 on the counter shaft. Unless I'm mistaken, that gives 2.46 for 1st. I see that Quantum agrees - http://www.quantumechanics.com/qm-htm/triumph1.htm. - Larry
