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

Weight: 173g

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.

How many dog toys have you bought that just laid on the floor unused?
Color: Orange
New husky has more energy than an entire pre-school - even being walked more than three miles a day wasn’t sufficient to drain her excess energy. I threw the dice on this - and it’s AWESOME. Comes with an extra rope and an extra side piece. Rechargeable with a USB-C cable. When you turn it on, the blue LEDs flash, the entire device buzzes, bounces, and races back and forth across the floor. After a couple of days of uncertainty, my new husky LOVES this. She chases it around, grabs it by the attached rope and carries it from room to room. After a short bit of activity, the toy goes into ‘sleep’ mode, until either the dog touches it again or a timer has elapsed, and then it fires up and starts buzzing and racing around the floor again. From a full charge, the toy will keep your dog entertained all day. Bright orange color makes it much easier to find when it’s rolled behind the toilet (as it did this afternoon). Sturdy. Highly resistant to chew damage. If this one wears out or breaks, I’ll absolutely get another one.

Puppy interactive toy
Color: Orange, Color: Orange
It’s a great toy as it keeps my 5 month old puppy very entertained! It is pretty hardy and made of good material as she tries to throw it around and chew it. She does swing it around and the hard part will hit her. She doesn’t seem bothered by it tho lol good size and minimum noise When I first introduced her to it she was a little scared but now she gets excited to play with it once it finishes charging.

My Dog Is Obsessed With This Toy!
Color: Orange, Color: Orange
My dog absolutely loves this toy and plays with it every day. The moving and rolling action keeps him entertained much longer than regular toys. He loves chasing it around the house and tugging on the rope. It’s also nice because it helps burn off some of his energy indoors. The material feels pretty sturdy, and charging was easy. Definitely one of the best interactive toys I’ve bought for my dog!

Waste of Money
Color: Orange
Cool toy but my dog ate through it the second day he played with it. It is not for strong dogs. No durability. I had to throw away the orange covers and now he just throws it around.

Cool toy. Fun for all
Color: Blue
A cool toy. entertainment for the dogs but more so for the dog parents to watch the dogs reaction. Comes with an additional rope just in case, which I loved. Only side note I would say is that the fast mood could be a little faster. My Golden retriever figured out the speed in less than 24 hours and now picks up the toy to try to chew it up, instead of chasing. With him attempting to chew on the toy in the small time I give him, there are no teeth marks yet…this toy appears to be durable. We play in short increments but enjoy the toy.
