Velo Orange Eccentric Bottom Bracket: Update

 Note: The Velo Orange Eccentric English Threaded Bottom Bracket for 24mm spindle cranks was purchased by Guitar Ted at retail. Velo Orange did not ask for this review and all opinions are Guitar Ted's.

In the introduction to this component, I revealed a couple of limitations to its use which have made me make a decision on my direction concerning the drive train for the Singular  Buzzard. (Crazy Idea)

The big thing here is I had set up the bike as a 2X, so there is a left shifter and a front derailleur. I had this dialed in perfectly, as in "chef's kiss" perfect, and I was loathe to remove it to go 1X. Making the change to 1X would simplify things 100% though, so.... I guess I was going to have to do this and scrap my plan for the 2X.

Of course, this would mean I would either have to convert the 2X crank to 1X, or find a 1X crank somewhere. Fortunately N.Y. Roll had given me an XTR 1X crank set a few years ago and despite some cosmetic blemishes, it was in fine working order. Using an Enduro bearing in the drive side, which I had found in my parts stash, made for a set up with no "top hat" shim on that side. I still have to decide what I want to do on the non-drive side. I suppose another Enduro bearing wouldn't be a bad idea there. 

I need to think about the gearing now that I have a single front ring. That ring, as you can see from the image here, is a 36T. I'm good with this as a front drive ring. My low gear in the cassette is currently a 34T. Yeah..... That's probably not quite enough.

So, I'm probably going to be looking for a wider ranged ten speed cassette, a new chain, and a decision on bearings on the bottom bracket. I'd like to have used the stock Velo Orange top hat shims and bearings but they just are not quite right.

I'll get something figured out with this entire set up sometime soon, but it may take me a bit, ya know, considering all I have been going through here. But now you know the plan and where I hope to end up.

Once I get all those bits on the bike and running I just need to find my stash of six bolt rotors and the front wheel can then be fitted with the proper rotor. The final part will be a single speed freewheel. If all goes well my "Crazy Idea" bike will be finished and I can demonstrate the single speed bail-out mode which the Velo Orange bottom bracket will be an integral part.

Programming Note: Tomorrow is my son's memorial service. Instead of running the usual FN&V I am going to post his eulogy which I wrote. So, that will be Friday's post and then we'll get back to regular blogging on Saturday. Thank you all for your kind comments and support during this difficult time.

Look at the Microshift cassettes. I have been very pleased with the 9-sp versions
