Description of Wolf Tooth Elliptical - Direct Mount Boost Chainring for SRAM Boost - Drop Stop - black

Wolf Tooth won't try to convince you that elliptical (or oval, the same thing) chainrings will change your life...but they might! What the engineers of Wolf Tooth can say for sure is that their Powertrac rings have a different feel from round rings and can provide an efficiency benefit and smoother power output for some riders. Testers report the biggest benefits on punchy singletrack and hills, allowing less shifting and faster acceleration.

Wolftooth elliptical Direct Mount chainrings with the special Drop-Stop teeth profile for preventing a falling off of the chain.

This chainrings is compatible with 1x10, 1x11 or 1x12 speed.

Fits for SRAM Boost cranks.

Optimized to work with 10/11/12-speed chain. If using a 9 speed drivetrain use a 10 speed chain (shifts and works well on a 9 speed drivetrain and fits the ring tighter for better chain retention).
Chainline 52 mm.
Offset: 3mm

Powertrac

More power? Check. Better traction? Definitely. Less shifting? Yup. Funky uneven pedal stroke? Not with Wolf Tooth’s PowerTrac Elliptical™ (PTE) chainrings. The proprietary design means a slightly less ovalized ring (10%) with less aggressive timing (112°) than competitors’ versions; any change to your pedal stroke is unnoticeable for most riders, but they still provide the POWER and TRACTION benefits inherent to oval chainrings.

It’s like having two chainrings in one! With PowerTrac Elliptical rings, the larger-diameter section of the ring engages with the chain at the optimal point on the downstroke, or "Power Zone" – between 1-5 and 7-11 on a clock face – to take advantage of your body’s natural biomechanical POWER: For example, during this section, a PTE 34t ring is equivalent to a 36t round ring. Similarly in the "Recovery Zone" (11-1 and 5-7), the smaller section on the PTE ring engages, maximizing EFFICIENCY in the weakest part of the pedal stroke; here the PTE 34t ring is equivalent to a 32t round ring.

Additionally, the above provides a smoother, more efficient pedal rotation, which means better TRACTION. Steadier torque on the rear wheel means less spinning out in the "Power Zone", while pedaling is easier during the "Recovery Zone", so you maintain momentum.

Hervorragend
Ich fahre das Blatt an einer NX-Kurbel mit Shimano XT Schaltwerk (10-51), -Kassette (10-45; dank neuer Laufräder mit Micorspline), -Hebeln und SRAM Kette.
Vorher hatte ich eine 11-50-NX-Kassette und ich vermisse nichts (Eher habe ich mit dem 10er-Ritzel gewonnen).
Dabei muss ich aber sagen, dass ich ein Drehmomentfahrer bin, also eher der Typ Stampfer mit Flatpedals, der nicht auf den Rundlauf achtet oder geachtet hat.
Für mich hat sich quasi nichts geändert außer dem, dass ich besser die Hügel hoch komme.
Bin begeistert!
