SUPER LOW FRICTION X-SEALS
Patented technology uses Low Friction Dual Lip Seals housed in the Premium bearings and CNC machined alloy cups. This allows the seals to fit very precisely and allow for less contact between the rotating parts in order to reduce energy-wasting friction. In addition, the seals provide better protection for the bearings since there is less space for the elements to get past the seals.
SUPER SMOOTH
Premium ABEC 5 standard, Grade 5 Chromium Steel Balls, and polished 52100 High Carbon Chromium alloy races sealed with X-SEALS. Extremely close tolerances for I.D. and O.D., roundness of ball, trueness of the races and micro surface finishes of balls and races.
SUPER LIGHTWEIGHT & STIFF
Strong and stiff CNC machined hollow titanium shaft for extra weight savings. JIS 2.0 degree square taper shaft.
SUPER LIGHTWEIGHT
CNC machined durable forged aluminum alloy cups with X-SEALS.

GREAT QUALITY AND LIGHTWEIGHT IF NOT A LITTLE PRICEY

Sent an email to the company asking for the torque settings of the BB I purchased. I'm impressed. Asked beforehand, and got a quick response, while waiting for the BB in the mail, not realizing how comprehensive their documentation in the package is.Been overhauling my MTB. Swapped BB, crank, pedals and chain. Just finished a standard 5 mile ride around a perimeter road of a nearby airport. Usually a 31 minute ride. Today I did it in just over 27 min. Used more power (watts), because I typically do this run at sunset but, today I did it earlier and with more windy conditions. May seem counterintuitive coming in faster, but the ride was just steady, smooth and, above all, a lot more effortless than before. Pure efficient power. This BB feels like butter on ice.Fantastic Product!

Easy to install. I did not weigh before I put on bike. But felt lighter in my hand than old BB,

Very light. Pretty smooth. So far I'm happy with it. It is 50% lighter than the Insight brand sealed BB I was about to use. The Omni is also 40% lighter than the unsealed Euro BB setup that came with the bike. I put this Omni on a DK mini for a little kid, so I can't attest to using this BB with a 200+ lb adult on a Pro XXL bike.

Mine (107mm width) weighed in at 170g including crank screws. Everything fits together very nicely, and the motion is beautifully smooth. Not the best value in weight loss per $, but a very nice, sexy part (that nobody but you sees).

Very nice unit

My previous bottom bracket had relatively small 6903-2RS sealed bearings that only lasted about two months before self destructing. This bottom bracket has a larger sealed bearing (maybe 1/4 inch) that so far have made it past the three month without any roughness. Workmanship is top notch, unit is a perfect fit and it is as light as advertised. The hangar bolts shipped with my unit were not titanium. With the chain off and spun in the bottom bracket the unit spin is tight when first installed and does not spin as freely as loose ball bearing spindle and cone set-up does. After about two hundred miles of riding the unit spins without noticeable friction drag and will settle back and forth until it stops at its heavy point. Nice. I highly recommend this unit to anyone considering a titanium bottom bracket.

This thing is the business. Super light, stiff and looks good to boot even though you can’t see it. Wish they made the alloy cups in anodized gold though, but that’s just my obsession with changing any silver part to gold on my bike. It weighed in at 160 grams, combine it with the conquer elite ex crankset and you have a track crankset that weighs nearly 100 grams less than Omniums and is just as stiff. This thing spins really well to boot. 10/10 would buy again (and you should too!)
