Why Choose Narrow Wide?
The Benefits of the sharktooth profile outlines
The term narrow wide refers to the unique tooth profile of all 1x chainrings from The Mechanic Parts, which are specifically designed to hold the chain extra firmly. The teeth alternate between narrow and wide, allowing them to perfectly grab the inner and outer links of your chain.
The narrow wide design offers several advantages. The chain is gripped much more firmly by the chainring due to the sharktooth design, which prevents the chain from moving sideways and jumping off the chainring. This allows you to rely on your equipment, even on the bumpiest roads or the most explosive sprints.
In addition, a narrow-wide chainring optimizes the way your power is transmitted. The tight fit ensures a more direct and efficient power transfer from your crankset to your rear wheel. This leads to less friction and a quieter drivetrain. Furthermore, this translates to a smoother cadence and less resistance.
Additionally, The Mechanic Parts’ narrow-wide chainrings are equipped with special mud cutouts between the teeth. These cutouts ensure that mud, sand, and other dirt are easily shed, which reduces wear on your chain and chainring. This significantly reduces the chance of mechanical failure for cyclocross racers, mountain bikers, and gravel riders.
Frequently Asked Questions
No. Narrow wide chainrings are specifically designed for a single-ring (1x) drivetrain. The unique sharktooth profile is not compatible with a front derailleur. The narrow-wide profile grabs the chain so firmly, it’s impossible to shift between multiple rings.
In most cases, no. A narrow-wide chainring, in combination with a rear derailleur with a clutch, already provides a very high degree of chain retention. However, our chain guide can provide extra security in extreme conditions, such as a very bumpy descent or an extremely rough mountain bike trail. This further reduces the chance of a mechanical failure.
No. All of our narrow wide chainrings are made from 7075 T6 aluminum, which is the highest quality aluminum. You can further prevent wear by properly maintaining and regularly cleaning your bike, especially after muddy rides.
An aero narrow wide chainring has a solid, full profile to minimize air resistance. It fits perfectly on the crank, which provides an aerodynamic advantage. A normal narrow-wide chainring, on the other hand, has a more open, lightweight design that is perfect for gravel, cyclocross, and mountain biking.
A normal chainring is slightly lighter than an aero chainring, but this difference is minimal due to the weight savings on the back of the aero chainring.
Yes, we also have oval chainrings! The oval design helps to overcome the “dead spots” in your pedal stroke, which can improve efficiency and comfort for many riders, especially on climbs. Our oval chainrings are not standard stock items, but we can always produce them. Please contact us via the contact form to arrange this.
