Wolf Tooth's T47 Internal bottom bracket, machined at its Minnesota HQ, isn't just another component, it follows the company's philosophy of producing precision engineered, lightweight products. Made from aerospace grade aluminum, it has carefully positioned seals, O-rings and end caps to shield the bearings from the harshest conditions, making it as tough as it is smooth.
With an adjustable shell width that allows it to fit 85.5 and 92mm shells, it features durable, low friction and corrosion-resistant, custom chrome bearings, with the ball diameter, width and counts all selected by Wolf Tooth for top quality and optimal longevity.
Wolf Tooth has designed its bottom bracket to withstand the toughest elements that can be thrown at it, with O-rings on the spindle and inner shell, a wiper connection seal between the bearing and end cap, bearing race seals and finally a labyrinth end cap design, to meticulously lock out dirt so that your ride stays smooth and silent.
Metal on metal or spindle on bearing races are common causes of creaking. An engineered polymer bushing isolates metal on metal contact on the bearing inner races and crank spindle, putting an end to unwanted noise and wear.
Available in a range of anodised colors to match the rest of the brand's products, the bottom bracket is easily serviceable and repairable, with spare parts available through Wolf Tooth's ‘Right to Repair’ scheme. You can also feel confident with a Lifetime Warranty, because Wolf Tooth believes in what it builds.
