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.

beautiful
Color: XY010-Silver
Purchased for granddaughter to keep in her bathroom. She normally removes jewelry and leaves on sink. A $40 bracelet was lost into the waste basket so this will prevent that. Came flat so I gently bent the branches and it is now a 3 dimensional tree . Beautiful.

Awesome -- they work perfectly
Style: Updated 3.46in Magnet L Red Hooks 2PCS
Got these to store a DeWalt cordless drill and impact driver on the side of a Gladiator garage cabinet -- and they work perfectly for that. The magnet is incredibly strong, easily supporting the bare tools, and seems even to work perfectly well with an 8ah XR battery on the tool -- not that it's necessary since I don't store them like that. I like that the magnet is padded with rubber. Very nice units, I will get more for sure to store other items.

Incredibly strong magnets and thick, robust hooks. Excellent combination!
Style: Updated 3.46in Magnet L Red Hooks 2PCS
These magnetic hooks are really strong. Seriously! Each part is made to carry weight and last. The hooks are built out of thick steel stock. They bolt up to large magnets that grab onto steel surfaces and won't let go. The cabinets in my shop are all steel so these worked perfectly on the sides of the lower units. I have a few #12 AWG extension cords that are bulky and heavy. Truthfully, I didn't think these hooks would handle them. They do without any issue. Another application is a 30' long #10/4 AWG SO cable that powers my powder coating oven. It's usually unplugged and wrapped up. It would often end up on the floor where it was constantly in the way. The outside of the oven is all steel but I didn't want to make holes in it for cable hangers. Again, I didn't think that these magnetic hooks could possibly be strong enough to handle the weight of that cable but they do. And once they're attached, it takes a lot of effort to remove them! Amazing performance!! I'm thrilled with these magnetic hooks. They are super strong and, obviously, simple to use. Importantly, they stay in place as they should. I wholeheartedly recommend these hooks to anyone. Great product! Incredibly strong magnets and thick, robust hooks. Excellent combination!

Great for the storm shelter!
Style: Updated 3.46in Magnet L Red Hooks 2PCS, Style: Updated 3.46in Magnet L Red Hooks 2PCS
In our storm shelter we had some lights that we tried to hang up, multiple times, with no luck! Then I found these garage hooks. They are overkill for the lights, but I’m so happy that we now have lighting in the storm shelter. I could think of so many other uses for these. They strength of the magnets is awesome!
