Dura ace 7700 bottom bracket on my new NJS frame - Questions

So the New (to me) Makino 2019 frame I'm waiting impatiently to be shipped from Japan comes with a dura ace 7700 bottom bracket

What are my options?

I have a 7710 bottom bracket and 7710 cranks on another bike and haven't had any complaints yet - but I've read mixed reviews on the 7700 bb and I'm wondering should I just get another 7710 crank or switch it out for something else.

Am I correct in my understanding that the threading on my new frame will be Italian and not English and therefore not compatible with most standard offerings?

Im not knowlegable about bike maintenance so please bear that in mind if you are generous enough to share your advice.

The 7700 BB is a serviceable ball and needle bearing BB. It's wonderful. It should arrive as smooth as butter. Put your cranks on and ride it like you stole it.

Maintaining a track bike isn't difficult. It's just mysterious. Knowledge and a little practice will eliminate the mystery. You live in the greatest period of human history when it comes to technical knowledge sharing (literally).

You can learn how to service that bottom bracket and actually service it faster than you can drive it down to the bike shop and drop it off for the same service. You'll have to buy some tools, but these are inexpensive tools that you'll keep as long as you enjoy bicycles. It's OK if you aren't into maintaining your bike, too. No shame in that. Find a nice local shop to take care of it for you. But, don't sell/trade this BB. You may have more appreciation for it later in your cycling career.

Oh, and you should ask the seller how your BB is threaded. Of everyone involved (you, me, this forum, and the seller), only the seller knows for sure.

Oh, and you don't need to buy a Dura Ace 7700 or 7710 bottom brackets to mate with your Dura Ace crank arms. They can get to be pricey. You can get lower tier Shimano Octalink BBs as well. I can't recall which tier it was ("105"?), but I bought one for like $25 once. So, they are (were) out there. Performed just fine. I think they may weigh a bit more (some small amount).

Thank You Carleton - very helpful & much appreciated.

I have emailed the seller and will hopefully know more before the frameset arrives.

I should have told you that no NJS frame could have an Italian bottom bracket shell.

Happy to oblige.

I cant believe how quickly it got here.

First off a better picture from the fine folks at NJS Export than what I can take with my phone

chrysalis stage freshly unpacked...

Free at last!

I learned from my last NJS Export purchase a few years ago that I love me a Columbus max fork!

So many questions - couldn't find anything online about either of these tubesets anywhere but I trusted the makers reputation -- anyone have a clue?

It really is amazing how quickly things get here from Japan. I think I placed an order from NJS-Export on a Thursday and it was delivered to my house on the East Coast on Monday.

I love the paint scheme --

years and years ago, Centurion made the Ironman series of bicycles with a "Smoke on the water" paint scheme ---- this reminds me of a modernized version of that

Never heard of Reynolds 565 either, but ive definitely heard of Makino , so i'm with you -- if they think its GTG, then it probably is

Nice - if you'd like please post a pic - what was it that made you choose that particular frame?

Interesting - a quick google image gallery search didn't give me anything - if you have a picture I'd love to see

& if you like this paint scheme NJS Export has several right now,(just type 'zebra' into the search feature)each a little different - some I like more than others.

Looks like Centurion didnt do the whole frame that way, just the front end and the stays -- my memory is foggy

Sorry. I should clarify. I ordered rings and cogs.
