The Dura-Ace BB-7700 is the fastest and smoothest in the BB-7700/7710 line-up, designed for the Track racer in mind.

Thanks to the inclusion of a lockring and adjustable pre-load cup, this setup allows for a smooth and precise install, allowing your cranks to spin fast and spin smooth when set up. The perks of a BB-7700 doesn’t just stop with its speed, the ability to service and overhaul the 36 (1/8”) ball bearings (Spare Part: Y1TF98020 – alternatively you can use our Ceramic Upgrade kits found here) if you notice any wear occurring. Not only this, the BB-7700 has 36 needle roller bearings (Spare Part: Y1TF98090) which provide unparalleled stiffness for the most demanding situations which can be rebuilt with moderate ease.

We are often asked when fitting these which is the best grease? We recommend the use of either Shimano Dura-Ace Premium Grease, or Motorex FETT2000 – both of which strike an uncanny resemblance to each other – If you need a small amount of either of these, please reach out to us. We don’t recommend the use of alternative grease in these units, as we have seen other grease cause uneven wear as well as a reduced lifespan.
 
These Bottom Brackets only suit FC-7710 Dura-Ace Track Cranks.

We are often asked if the BB-7710 or the BB-7700 is the best option, and the answer is pretty simple – Do you ride Track or on the Street?
Our handy breakdown below might help you make a decision too.

BB-7710
Sealed Bearings
Suitable for people riding in all weather conditions
Little to no maintenance required
Cannot be serviced

BB-7700
Unsealed bearings
Suitable for Indoor track racing (and out-door in fair weather)
Requires yearly maintenance
Requires pre-load adjustment for correct setup – We recommend a skilled mechanic
Fast Rolling

Typically, for anyone riding fixed or on the street we always suggest and encourage the BB-7710 bottom bracket.
If you’re a Track rider and only using it on the indoor Velodrome, the BB-7700 is by far the fastest rolling option – when setup correctly.

Poor formatting on kindle version
Format: Kindle
Five stars for the book, 0 stars for the formatting of this kindle version. Every word that contains a double "l", such as "all", "Stillness", "hill", etc. omits the second "l" in the word. Universal y. Kil. Al. Germ cels. It is extremely annoying, and one or more on nearly every page. Is it possible to swap this one for a kindle version with better formatting?

Intense and Informative
Format: Paperback
This is some intense and easily consumed deep reading material, compelling us to gaze uncomfortably at and into the unflattering challenges which continue to face the African-American collective "Community," and delves head-on into examining & explaining how the "HISTORICAL EXPERIENCE" of Black People in the United States, those who were the unfortunate descendants of the Trans-Atlantic African Slave Trade, has both simultaneously "Strengthened" and "Hindered" hindered life for this segment of the North American population across the Generations, to where many of its effects are still being felt even to this very Day. This is a powerful companion to Dr. Carol Anderson's excellent book on on the Societal struggles of Blacks in America - "WHITE RAGE: The Unspoken Truth Of Our Racial Divide"

Post Traumatic Slave Syndrome
Format: Hardcover
Very well done book that does not make Black People feel angry nor White People guilty but from a gentle and skillful psychological point of view the book will "have you considered the impact of this or that upon both races as the result of Slavery in America?" A folk-like homespun way of tell these truths that masks the clinical questions that all trained psychologist asked..."and how would (does) that make you feel for all of us who ever sat on a couch?" The book made me consider the psychological impact of daily slave life with a WOW again and again as I never thought of the situations the book made me consider. The shared dehumanization of both whites and blacks due to the slave experience which goes a long way towards explaining to me why we as a country cannot truly discuss slavery's impact today. I found it self-healing and very necessary for all, both black and white, but especially for the victims of the African Holocaust my terminology not hers. I thought Dr. Leary PhD, did an excellent job and a high school or even a 6 grader could read the material without difficulty.
