Enduro has announced a new series of bottom brackets called TorqTite that promises to eliminate persistent creaking issues. Although TorqTite is designed to fit frames with press-fit bottom bracket shells, it uses a clever thread-together design for a secure – and hopefully quiet – fit.
Instead of merely pressing into the frame like standard PF30, BB386EVO and PF86/92 bottom bracket cups, TorqTite bearing cups are internally threaded and connected to each other with a central sleeve.
When the whole assembly is tightened down, the frame is effectively clamped in between the cup flanges for a much tighter and more secure fit than you typically get with press-fit plastic cups.
Both cups are threaded together via a central sleeve. when the whole assembly is tightened down, the frame is effectively clamped in between the cup flanges for a much tighter and more secure fit than what you usually get with press-fit plastic cups:

There will be no chintzy plastic bits to be found, either. Enduro is using machined aluminum for all of the TorqTite bearing cups and central sleeves, and they’re all made in the US near the company’s headquarters in Oakland, California.
Enduro will offer TorqTite in standard PF30, BB386EVO, and PF86/92 fitments. There’s also an additional PF30 Outboard model that adapts oversized PF30 frames for use with smaller 24mm-diameter crankset spindles, and a Cervélo-specific BBright version is pending. All versions will be offered with either stainless steel angular contact bearings or Enduro’s ultra-smooth and remarkably durable XD-15 cartridges. For now, color options will be limited to just red or black.
Also using the torqtite design is the new pressfit 30 outboard model, which adapts oversized pf30 frames for use with smaller 24mm-diameter crankset spindles:

Actual weight for the PF86/92 and PF30 models is 108g while the more involved PF30 Outboard tips the scales at 152g.
Retail price for all of the standard stainless steel TorqTite bottom brackets is US$199; XD-15 versions will cost US$289. Custom wrenches to tighten the PF30 and BB386EVO-compatible models will cost US$40 per pair; PF86/92 and PF30 Outboard cups can be tightened with standard Shimano-type spline tools. International prices are still to be confirmed.
