Shopping Tips For Chainrings
Find the best prices on chainrings for your road bike, mountain bike, or latest art project! "Art!", you say? There are all sorts of creative bike art pieces using chains, chainrings and other bike parts, such as a clock built into a bike chainring. Though most ready-made cranksets come built with chainrings in place, there is a huge after-market for chainrings that will fit fine with Shimano, SRAM, Campagnolo and many other cranksets. The standard road bike chainring configuration is 53/39, which means a 53 tooth large chainring paired with a 39 tooth inner chainring. This is for a double setup, meaning 2 chainrings, as opposed to a triple setup, which applies for mountain bikes and often road bikes geared for beginner riders or those living in areas with lots of steep climbing. A popular crankset that applies in such a case that there is lots of climbing involved is a compact crankset, which typically makes use of a 50/34 setup - 50 tooth chainring paired with a 34 tooth chainring. When you configure your bike drivetrain with a compact crankset, and then put on, say, a 11-25 bike cassette, you end up getting a decently hard top gear of 50/11 and a very manageable 34/25 "granny" gearing (well, it's not that granny!) to handle the hills. For time trial cyclists, they will often equip their TT bikes with big chainrings, such as a 54, 55, or even 56 tooth front chainring. Most all chainrings are made of alloy materials, but there are the rare cases of carbon chainrings. You won't see them often - carbon chainrings are strong enough to withstand the chain forces put on them, but it's the wear factor that really comes into play. Carbon chainrings, for this reason, are exotic bike items. Trek created what is called an elliptical chainring in the 1980's, the idea being that there are points in the pedaling rotation where more power can be transferred to a bike's drivetrain by creating a more advantageous angle for the foot/leg combiation to push on the pedals. The elliptical chainring design is making a comeback in recent pro time trial racing. Whatever your chainring needs are, for road, mountain, fixies, or BMX, you'll find the bicycle chainring you're looking for here on QBike.
