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

BB-7700

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.

TAKE THE TRASH OUT !
Style: White Pine Breeze, Size: 50 Count (Pack of 1)
I recently bought the Hefty Ultra Strong 30 Gallon Trash Bags and I am thoroughly impressed with their performance. These bags are perfect for handling heavy loads and tough trash, making them ideal for both household and industrial use. The 30-gallon size is perfect for larger trash cans, and the drawstring closure is incredibly convenient. It allows for easy tying and carrying, without worrying about the bag breaking or ripping. The drawstring also ensures that the bag stays securely in place in the trash can. The black color is great for concealing the contents, and the White Pine Breeze scent adds a pleasant touch that helps neutralize odors. The scent isn't overpowering but does a good job of keeping unpleasant smells at bay. These bags are truly break-resistant, leak-proof, and puncture-resistant. I've used them for a variety of tasks, from yard work to cleaning out the garage, and they have held up beautifully without tearing or leaking. The strength and durability of these bags are evident, even with heavy and sharp objects inside. Overall, the Hefty Ultra Strong Trash Bags are an excellent choice for anyone looking for reliable and durable trash bags. They offer great value for the price, and their performance has exceeded my expectations. Highly recommended for anyone needing a strong, dependable trash bag!

Perfect for garage and kitchen
Package Size Name: Super, Size: 81 sheet (Pack of 12), Package Size Name: Super, Size: 81 sheet (Pack of 12)
These are easy the toughest paper towels that I have use so far. I have been using these for years and they are the best. I love the quality because they feel more like cloths than paper towels that are thin. They are great when cleaning up tough messes in the kitchen or garage. This is the perfect size thickness but yet light enough to handle perfect. These soak up water and messes like a sponge and hold them tight. As you can see these are bright white and I have them in the open on my kitchen counter and it blends in just fine especially for decorating. I have been using these paper towels for years now and the these really are a great value for your money especially if you clean up a lot. The quality is also perfect because each roll last me for about 3 weeks and I use them everyday for various messes. These are also easy to tear into small sheets with ease. They are tough enough to hold together and not just fall apart it easy enough to tear alone the seems. Each roll will last you a good enough long time which makes cutting down on cost easy. I buy the 6 pack and they last me for about 4-5 months. So I love the quantity. I would say these are a bit more expensive than the generic brands but they are worth it.
