Ridley Liz/Shimano 105 Complete Bike - 2013 White X-SMALL

Ridley Liz/Shimano 105 Complete Bike - 2013 White X-SMALL Let's face it the sport of cycling tends to be slow in its adoption to change. - Whereas the powermeter used to be considered a luxury item for the most elite of pros (the types who sleep in altitude tents and wear space legs) it's now a prerequisite for anyone seeking success in the saddle. - Training with power is the most effective way to make your efforts count and at the forefront of this movement has been a little company in South Dakota called Quarq. - If you were impressed by Quarq's Cinqo Saturn or S975 powermeters you'll feel the same sense of excitement when you see the new Riken GXP. - So besides a $300 price difference the question begs to be asked how do the Quarq Riken and Elsa actually differ? Surprisingly the answer is not much -- that is if you're not a habitual gram counter. - In fact the overall functionality of the two systems are nearly identical only differing in the Riken's absence of the new Power Balance feature. - However where the two most noticeably part ways is at the crankarms themselves. - Where the Elsa utilizes the newest SRAM Exogram Hollow carbon arms the Riken relies on a more standardized RED pair of arms. - Ultimately though this only amounts to around an 88 gram differential So let's focus on the Riken. - For Quarq's 'next wave of powermeters' we see a complete redesign over the Cinqo with an emphasis placed on three key issues -- weight accuracy and ease of use. - And starting with weight the Riken features SRAM's carbon crankarms found on the last iteration of SRAM RED. - You'll also find SRAM's RED Powerglide chainrings from one model back. - But as the name implies the cranks feature a hollow construction. - However what isn't inferred is that the hollow cross-section design extends all the way to the new spider creating SRAM's stiffest and lightest crank ever. - In fact the complete system tips the scales around 823 grams. - For some perspective the newest RED crankset weighs around 585 grams and the last Quarq RED Ex. -. -. -Bike>Bike Parts>Cranksets/Chainrings>Road Bike Cranksets & Chainrings1595 More Details click ******************************************************
