"[35mm] allows them to make the spindle from thinner walled alloy, which makes them stiffer for approximately the same overall weight. Combine that with the wider stance of their outboard bearing bottom bracket conversions and you get something massively stiff." Read More
"APTOS, CA—There may be a sliver of light at the end of the tunnel for retailers frustrated with creaky, plastic-y, non-serviceable OEM bottom brackets in $8,000 bikes. A new generation of aftermarket designs goes directly after creak and serviceability issues. Cartridge designs from Praxis Works are made of aluminum and thread together inside press-fit shells."

"A trick collet system on the central sleeve expands up against the inner walls of the shell as the two halves of the bottom bracket are threaded tightly into each other, too, making for a rock-solid fitment and a virtual guarantee against creaking." Read More
"After several hundred miles on various setups with the Praxis rings, we'd recommend them in a heartbeat to anyone needing to replace their chainrings or would like to improve their shifting right from the start" Read More
"The 36-52 is becoming a popular alternative to the usual 34- or 36-50 compact cranks, offering a top gear almost equal to the typical 39-53 full-size combination. Praxis claims to offer the only cold-forged aftermarket set in this size. The cold-forging increases durability and allows optimum ramping and tooth shapes for shifting performance." Read More
"We've already long been fans of the Praxis Works Forged chainrings, and now that they’re offering a 52/36 chainring combination for compact (110 BCD) cranks, they give us just one more reason to rejoice." Read More

"Single chainrings are becoming increasingly popular for XC racing, and remain a near-undisputed choice for gravity-oriented riding. Praxis Works helps you dial in your gearing with their durable, good-looking rings..." Read More
"The real draw, however, will be their incredible stiffness. Pedaling efficiency should be among the best in the industry with the enormous arms and spindle but the stoutly reinforced spider arms..." Read More
"The new chainring is fully engineered to work with the 110 BCD crank standard allowing riders to hammer in the 52, but drop down to a 36 when the grades start to go up." Read More
"Using their M35 bottom bracket, which fits into any BB30 or PFBB30 frame but puts the bearings outside the frame for a wider stance. This also lets them give their crank spindle a 35mm diameter. Yes, 35 millimeters." Read More
"Praxis says that understanding, and carefully managing, the relationship between the chain and chain ring is the key to good front shifting." Read More
"Praxis forge their rings, which, they say, allows them to offer more heavily engineered ring designs — i.e. better shifting — without the costs associated with more machining." Read More
"...know that they're the only other company (other than Shimano) that forges its own chainrings." Read More
"This is a product that is better than virtually everything else (aftermarket and original gruppo production) shy of Shimano's Dura Ace. The road result of the detailing is better shifting under any conditions up or down shifting versus stamped / machined rings. Far less lag / a far crisper pick up and a simple pronounced drop than standard SRAM Red, FSA or any of the other aftermarket rings"... Read More
"Nothing says you can bend metal to your will better than forging a chainring"... Read More (pdf)
"I am going to get straight to the point. You want these chainrings and you want them right now! These are the only chainrings I have ever ridden that have equal, if not slightly better, front shifting performance as compared to a Shimano Dura-ace set up."... Read More
"This Northern California design shop is doing something that sets them apart from nearly all the other chainring makers: forging."... Read More (pdf)
"Using a proprietary forging process and their LevaTime shifting technology, Praxis is producing chainrings that easily surpass the performance and durability of CNC-machined chainrings and rival top forged rings but at much lower prices."... Read More (pdf)
"By pounding solid metal into shape, forging is faster than machining and adds strength"... Read More
"the teeth are exclusively formed using a giant hydraulic press so the shaping of each tooth is much more complex than machined ones"... Read More
"A product of years of relentless testing and tweaking, LevaTime is a combination of intricate features and timing points built into the chainrings to allow for fast and consistent shifting"... Read More
"One thing that is so impressive is that you get the shift quality of Shimano rings, but with the weight of TA rings"... Read More
