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
Weight: 244g

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
Can be re-built and overhauled by a skilled mechanic
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.

eh
Format: Paperback
IT's not bad at all but they're other "The Simpsons" comic books are way better. I really recommend "Belly Buster" or "Madness" from The Simpsons collection.

"I very nearly singed my bone!"--Melvin Van Horne
Format: Paperback
Another fun-packed issue of Simpsons Comics. This is the 15th issue I've bought and, with only a couple of exceptions, they are all as funny and entertaining as the television show. I've read them all multiple times. This issue is perfect for the Sideshow Mel fan because he is featured in a short that documents how and why he became Sideshow Mel and he is also the hero in another comic. Jimbo Jones fans will like the short about how he became a bully (he wasn't always one). Dr. Hibbert also has a short feature. Here's what this issue has to offer: "Simpson/Sideshow Sibling Smackdown": Cecil Terwilliger and Lisa have something in common--they can't escape from the shadows of their attention-grubbing older brothers. Can they find a rapport even as one is intent on destroying the other? "A Recipe for Disaster"--Marge needs a new dish for the church social pot luck and tries recipes written by "Springfieldian citizens of questionable character." "Homer's Run"--Bart becomes owner of a demanding falcoln ("I have to do everything for him. What a stupid bird") while Homer signs up for early retirement on the Hawaiian Island Garbagio--which looks (and smells) just like it sounds. "Secret Origin of Sideshow Mel"--The background story of how and why Melvin Van Horne became Krusty's sidekick (you won't believe what Mel's occupation was before he replaced Sideshow Bob). "Day of the Nerd"--Lisa finds out the truth about NASA's exploration of Mars. Meanwhile, the other geeks of Springfield compete in feats of nerdome to win the inheritance of the largest collector of TV/movie&comic book memorabilia. Interesting and unique but jumps around a lot. "Bummer Vacation"--Short about Bart's summer (his batting swing looks totally wrong) and then writing a report on it that Mrs. Krabbapal doesn't believe. "Laughter is the Worst Medicine"--Homer competes in a competitive eating contest, "The Gorge in the Gorge." As Krusty says, "Chewing is for losers! Once you swallow, it's the colon's problem." After eating the final hot dog, something goes horribly wrong. Meanwhile Krusty gets a real doctor's degree instead of an honorary one and sick people start lining up at his door. "Down Home Doctorin' Time with Doctor Julius Hibbert"--Short about Dr. Hibbert as a TV doctor forced to change the style of his show to get better ratings. Ends very abruptly. "The Permanent Record Room!"--Principal Skinner shares some stories (school stories, not war stories). (1) "Pranks But No Pranks"--Bart plays a joke on Groundskeeper Willie which has the janitor believing he's a superhero. (2) "And the Beatings Go On"--The origin of Jimbo Jones. No, he wasn't always a bully. (3) "Truant or False"--Lil' Homie gets hooked up with a young miscreant(who would grow up to become a prominent figure in Springfield). Homer thinks he's learned a valuable lesson from the breif time he spent with this rebelious kid, but perhaps it is the rebel who changes his ways. Sidenote: they wouldn't have had Noiseland Arcade if this comic was accurate. Homer's mother is in this comic and she left the family in 1969. "The Many Faces of Bob"--Sideshow Bob is released from prison but is hit by a Duff Beer truck on his way out and has to undergo plastic surgery. Bart and Lisa try to figure out who Bob could be posing as before he gets his revenge on Bart. "Homer vs. The Raccoon I & II"--I'm not sure why this was divided into two parts; it's just an 8-page short. Anyway, Homer tries to capture a raccoon that has been going through his trash.

This collection had some really fun stories involving some of Springfield's residents. There is a story on Sideshow Mel's origin, SIdeshow Bob comes back, the Simpsons find a new home on an island of garbage and much more. If you like the Simpsons, this collection has some really entertaining tales that fit in with the world of the show. Awesome
