Wolf Tooth Components CAMO Aluminium Elliptical chainring - oval and for CAMO
The Wolf Tooth Components CAMO Aluminium Elliptical chainring is an oval chainring for use with the CAMO spider by Wolf Tooth. With its elliptical shape, it accommodates the biomechanics of pedalling and also increases traction. Thanks to Drop-Stop® technology, chain drops are counteracted and the load is distributed evenly. CAMO is an integrated chainring spider system designed to optimise the characteristics of direct mount chainrings. The main advantages are a perfect chainline for less wear and more shifting precision, an optimal utilization of the material to improve the stiffness/weight ratio and a favourable price as a spare parts.

- increased and more even pedalling performance, more efficiency in the recovery zone and more traction thanks to constant torque
- timing: 112° to TDC (Top Dead Center)
- less wear, more shifting precision, faster chainring change
- stainless steel bolts supplied with the CAMO spider
- Made in the USA
- Note from the manufacturer:
- It is best to use a clutch rear derailleur. For very muddy conditions a chain guide in combination with clutch rear derailleur is recommended.
CAMO stands for Chainline And Material Optimisation, i.e. an optimisation of the chainline and material of Direct Mount chainrings. The chainline is decisive for the function of a 1x drivetrain. CAMO is available for 4 different chainline options. CAMO spiders are made of 7075 aluminium, which is very light, stiff and strong. The CAMO chainrings are either also made from aluminium or from ultra-durable but exceptionally light stainless steel. Due to the coordinated spider chainring system the power transfer is optimised compared to conventional solutions. The CAMO system makes the supply of spare chainrings more affordable and simplifies chainring changes. All five bolts are accessible without removing the spider. The small dot on the chainring must be in line with the dot on the spider. Connect the sockets of the spider to the chainring, tighten the bolts to 4 to 5 Nm and use blue Loctite.
PowerTrac Elliptical™ (PTE)
Wolf Tooth's PowerTrac Elliptical chainrings feature 10% ovality, in combination with 112° timing, which is measured according to the Top Dead Center (TDC). This means that the wider diameter chainring section engages the chain at the optimum point in the downward movement, the power zone. In this way the natural biomechanics of the body are taken into account.
PTE is like having two chain rings in one. This is because your pedal stroke is biomechanically weakest when your pedals are at the upper and lower positions of the circle (at 11 to 1 o'clock and 5 to 7 o'clock on a dial), also known as the " recovery zone" . Thanks to the oval shape of the chainrings, the narrower section grips at this stage, which makes it seem as if you have two chainring teeth less. It's as if you were instantly shifting to a smaller chainring, for example from 34 to 32 tooth.
The reverse is true for the power zone of your pedal stroke - when your front pedal is at 1 to 5 o'clock. Here, when your legs are at their strongest and most efficient, the PowerTrac elliptical has a wide diameter and works as if you have two extra chainring teeth, about 36 instead of 34.
The whole thing also benefits traction. The torque on the rear wheel is more even, so the probability of you overpowering and slipping in the power zone is reduced. It also makes pedalling easier in the recovery zone and maintains momentum. This " 2 chainrings-in-1" effect keeps the pedal stroke smooth and the torque constant at every stroke.
Wolf Tooth has invested countless hours in the design, prototyping and testing of their Wide-Narrow chainrings and has developed a highly innovative tooth profile. Test riders around the world have confirmed that this design brings unparalleled performance.
The right side of the chainring tooth has a different shape than the left side. The right side transmits the power to the chain and the left side opens a free space for cleaning mud and dirt. Since the two sides have completely different functions, it makes sense to design them differently, true to the motto: extra reinforcement where you need it, less material where you don't.
The right side of the Drop-Stop tooth is as wide as possible to distribute the load over a larger area, which also minimises wear. The left side of the Drop-Stop tooth helps to guide the chain, but it does not transmit any load. Therefore the left side is narrower than the chain roller. Wear is not an issue on this side, so Wolf Tooth was able to save material and create a better mud clearance channel. More free space means less friction and less change of the chain being dropped due to mud.
In the A version, the original version of Drop-Stop, the profile is optimized for use on mountain bikes. The wide teeth are slightly wider than Drop-Stop B. The outer sides of the narrow and wide teeth guide the chain.
