In a previous post, we mentioned the Eccentric 46 Bottom Bracket for use with PressFit-30 (PF30) bike frames. This aftermarket accessory allows you to be able to purchase a geared PF30 frame or bike and easily convert it to a single speed. But what about those of us who do not own a frame with a PF30 frame? Are we left out in the cold? Nope! There are solutions out there for those of us with the standard bottom bracket shell. Continue reading A Single Speed Solution for the Masses
Eccentric bottom brackets (EBB) have been used for years on single speed bikes to make the job of tensioning the chain easier than using horizontal rear dropouts. This solution allows the use of vertical dropouts in the frame and a quick release skewer to secure the rear wheel – a feature that anyone who has been miles away from home with a flat, but no wrench to remove the wheel would appreciate. With the advent of the oversized PressFit-30 (PF30) bottom bracket shell used in all types of bikes to provide a stiffer, more efficient power transfer from the pedal to the rear wheel has lead to an unexpected aftermarket part for those wanting a single speed bike – the Eccentric 46 Bottom Bracket from Problem Solvers of Bloomington, Minnesota.
With so many manufacturers offering 29er hardtail mountain bikes, it can be difficult to pick one that is right for you. Just as demo days that many companies host around the country for the public, the Interbike OutDoor Demo, that occurs each year before the Interbike tradeshow, allows individuals involved in the bike industry to test the newest and latest rides on the market. Not all manufactures are present, but most of the major players are there alongside the little guys offering a fleet of bikes to ride on the trails of Bootleg Canyon outside of Boulder City, Nevada. Having had a chance to test numerous bikes, 29er hardtails were this writer’s choice to put trough the loops of loose, dry and rocky trails of Bootleg Canyon. Before you lay down your hard earned cash on a hardtail 29er, give any of these bikes a spin. Continue reading Interbike 2011: 29ers Worth Riding
The Continental SAUR SOJASUN Team will be riding with ROTOR Bike Components for 2011 it has been announced. These include the company’s unique and innovative components including the Q-Ring oval chainrings, 3D+ cranks and BB30 bottom brackets, as well as chain-catchers and race-plate holders.
The revolutionary shaped Q-Rings have the promise of increasing power by maximizing the use of efficient zones of the pedaling stroke and reducing the intensity of the “dead spot” zones, while helping reduce joint and tendon loadings. The 3D+ cranks are 100 percent compatible with any BB30 or Class BAS threaded frame on the market.
ROTOR will be sharing the sponsorship with French bike manufacturer TIME. “France is one of our leading markets, in which we have quite a number of fans and high customer fidelity, so we want to thank them for this support by sponsoring one of the country’s leading teams,” said Ignacio Estellés, ROTOR CEO, during the contract signature in Rennes. “A strong professional team, well placed in the 2010 UCI rankings – above some ProTour teams – is a new proving ground for our technologies, increasing the brand´s fame and customer’s confidence in our products.”
Rotor hopes to help riders get pumping with its new line of 3D Cranks, Q-Rings and other products this fall. At Interbike The company is also introducing several bottom brackets that can be used with standard cranks in any BB30 frame, as well as their own 3D cranks of course.
Among the interesting new products are the 3D Aero & Track cranks, specifically designed for time trial and track bikes. These feature a “closed spider” design, and are made with an ultra-light, yet aerodynamic reinforced structure. The idea is to provide increased overall stiffness compared to an open spider crank, so as to help riders keep it turning on the track or during a time trial.
