Comments on: If the answer is 42 what’s the question? http://wheelsofchance.org/2009/08/28/if-the-answer-is-42-whats-the-question/ A bicycle blog Thu, 09 Feb 2012 20:54:15 +0000 hourly 1 http://wordpress.com/ By: Trefix http://wheelsofchance.org/2009/08/28/if-the-answer-is-42-whats-the-question/#comment-90 Mon, 25 Jan 2010 06:40:23 +0000 http://wheelsofchance.org/?p=406#comment-90 True, sorry.

First, it was on my ” rat bike “( with 52t-42t) and I’d just change rings. 28 is the lower ring allowed and a 69/107 mm BB gives perfect chain line and very low Q factor.

I’m not certain, but that Stronglight 80 you mention might have an 86mm BCD. Anyway 42 and something in the 20′s is a nice double.

Salutations cuclotouristes ;)

I like not having to think about front ring changes and don’t mind the large steps between gears as they are only an issue if you are racing. For a road bike I’d probably go with a 48/34 compact double with a 12/27 cassette.

I keep 11-32t in the back. The stock crank had a 50t, but I never used half of the cassette. The whole setup is 8 speed friction via ultegra bar end shifters.

I suppose a 42t would split the difference between my middle and big ring, but my setup has very easy front shifting as is.

My tastes for a road bike are totally different. I constantly am shifting the rear, but only sparingly shift up front. In that case, I like a lot of range on the front rings, but tight increments on the rear cassette.
