What size should I choose?
Most CX riders choose 38T as most versatile option. For Gravel 44 or 46T is a good start. If you feel strong try bigger size.
- 44T Oval chainring is best suited for someone who uses wide gravel tires, plenty of bike mounted camping gear or simply ride in mountain terrain
- 46T Oval chainring is best suited for fast hill riding with majority of gravel roads and some tarmac roads.
- 48T Oval chainring is best suited for someone who rides majority of tarmac roads and occasional off-road flat terrain
- 50T Oval chainring is best suited for road oriented riders with occasional flat fire roads
Remember when selecting your chainring sizes - it's not about what others use, but about ensuring YOUR ability to maintain a comfortable and effective cadence across the terrain you ride most often. If you ride chainrings that are too large (round or oval), your cadence will be lower. This can affect your performance by prematurely tiring your legs and possibly lead to stress injury in your knee joints.
* Do I have a perfect pedal spin?
This is an important one. Professionals and semi pro cyclists spin perfect "circles". The rest of us often struggle with our pedalling action, simply because we don't spend every day of every week on the bike, to master this skill. Switching to oval rings effectively correct an imperfect pedalling action – delivering the smooth power delivery the pros developed through thousands of hours of training. One of the key reasons the benefits of oval chainrings have historically proven hard to prove in lab tests, is because they were nearly always done using Professional riders – as a user group they are the least likely to gain a performance increase from a switch to oval, as their pedalling is already close to perfection. Where ovals shine however is with rest of us, who ride for pleasure and not for a job. Simply 99% of road cyclists will benefit from having oval chainrings on their bikes.
