? I guess it comes down to gearing? Is there an optimal set that would give the LHT a bit more speed if you wanted?
Well, according to Sheldon Brown's gear calculator it will hit ~35mph with your cadence at 90 (using a 46t ring and 700c tires... a 48t was also an option). Is that fast enough for you? The low end will be 7mph (cadence at 90).
