Of all the upgrades, I was most excited about Easton’s new carbon cranks. I’ve been using 9-speed Dura Ace with FSA Superlight Cranks (543 grams with bolts) and the reliable and light Dura Ace Octalink bottom bracket (175 grams). The combined weight of 718 grams seemed hard to beat; most of the newer 10-speed crank/bb’s actually weigh more. But since I switched to 10-speed recently, I wanted a crankset that was optimized for the 10 cogs. Easton’s crank was the one that was lighter without being quite as cost-prohibitive as some of the competition. Better still, the EC90 crank and bottom bracket weigh a total of 676 grams, a savings of 32 grams.
How does it compare?
So how can you objectively measure the relative worth of these cranks without riding them? To try and quantify this, I looked at the weights and MSRPs of the latest high end standard sized cranks (the FSA K-force Light TI was not compared because it is only available in compact). I then gave 100 points to the lightest and 100 points to the least expensive with proportionate weighting to each. Each crank is then graded relative to the best in class.
In the end, it’s very clear that there is a huge price premium for ceramic bearings; the jury is still out if the maintenance is worth the claimed reduction in friction. However, and more importantly, along these two judging criteria, the EC90 with standard BB has the best overall score. With the ceramic BB, it comes in at 3rd.
Looking purely at $/gram, the EC90 with standard BB slips to 2nd with the Ceramic BB version still at 3rd.
Not a bad empirical showing for the EC90.
