Among the (way too) many bike projects I have underway is a conversion of a Raleigh Grand Prix to pseudo-Clubman. I'm also changing a lot of the parts out for aluminium, including the entire drive train.

I said to myself "Self, get yourself a Velo Orange English threaded bottom bracket" and thought that would do the trick, but I spaced off the proprietary Raleigh threading. Oops! Back to the drawing board.

I know there are numerous ways to convert a Raleigh from cottered to cotterless and I'd gladly use one of those if I thought it would be a straightforward process. Unfortunately, the most commonly recommended ways of doing this don't seem like they'll work right now. An example of this is that Phil Wood is sold out of all of the "even close to the right length" spindles in their sealed bottom bracket. Velo Orange doesn't seem to sell their threadless bottom bracket anymore. I've pretty much hit dead ends in most of approaches I thought about trying.

In looking around for a solution to my problem, I came across the Sunlite Repair Threadless bottom bracket (https://www.modernbike.com/sunlite-t...tripped-frames) and this looks like it would work for what I have in mind. Has anyone used one of these to convert from a cottered to cotterless crank?

FYI, the drive train I'm planning is a Sturmey-Archer S-RF3 hub and a Handsome Cycles 42 tooth single-speed crankset. I'm also getting a Sturmey-Archer front hub and a buddy who owns a bike shop said he'd be happy to lace the hubs to some Sun M13-II rims that I have. I'm also planning on white fenders, a Brooks B17, using the stock Weinmann brakes with new levers and the original bars and stem. The last change I'm planning is an aluminium seat post.

I'm sincerely hoping that this is the worst of the parts-finding problems that I encounter with this project.

Here's my starting point:
