Anonymous asked: I feel I need a triple for climbing and my old knees. According to a report in the latest Bicycling, SRAM's WiFli (having a 11-32 ten-speed cassette and a double crank) may "kill the triple" because of the weight savings, improved shifting and reduced chance of derailment. Do you agree? Which manufacturers will carry the WiFli?
Dear Anonymous,
We are certainly seeing the “compact double” killing off the triple in many cases. The front rings on a Compact Double are usually 50/34 as opposed to a 53/39 on a “traditional” Double. The 34 is a big part of what can help you get to the same low range a Triple would. Sram was the first to introduce an 11-28 cassette to work with this “compact” design. They’ve raised the bar again with the 11-32 offering an even lower option, no doubt taking technology derived from their brand new 10 speed mountain group the XX. To answer your question, there is a lot of merit for a person looking for low climbing gear and improved performance over a triple. Let’s face it, the honing and performance of a modern triple is nothing to scoff at but these new offerings do provide improvement. Bottom line, the gear ratios between a Triple and Compact Drive Double can be virtually identical. The new C.D. needs less “throw” on the front derailleur for only 2 gear rather than 3 which means crisper shifts and lighter weight. You get more usable gears and less redundancy using the range on the cassette and the 2 front rings of a C.D. We don’t have bike spec’s for 2011 bikes yet but all our major brands now offer bikes with both Shimano and Sram options in a compact drive. I suspect we’ll see companies using this WiFLi idea but at the very least will give an aftermarket option for a wider cassette range on any compatible 10 speed group. Hope this helps,
