I hold you totally to blame for introducing me to this ;)

Just when i think i have got a handle on time spent looking at the interwebz i finally get around to having a good look on RRB.

I think this is a generic EZ Gains and not as expensive https://www.ebay.co.uk/itm/335994150454

Post more pics please 😀

+1 Always measure and keep the numbers in or on something. All you need is a decent ruler/tape to measure inside the rim, a spoke with a nipple to complete the ERD measurement, and a vernier caliper to measure hubs. None are expensive tools.

Next aero step is an aero big ring and/or chainset covers. You don't have to have a full aero chainring for covers to attach to but you will need a chainring with more real estate than those in your pic above Pretty simple, cheap, and cut your own hole for crank arm...

There is barely any ovality to the Biopace rings and i will be surprised if it makes any difference in shifting back and forth between a BP ring and a round ring. I have mixed round rings with Osymetric rings, that are really extreme, and in my experiments, with a friction shifter, they shifted...

With modern rims i think you can make strong narrow flange wheels. With low spoke counts, too. Flanges have been getting closer and closer with increased cassette sizes and discs , but even with dropout spacing increasing the drive side spokes are really dished. Not far from being almost...

Absolutely first class 👍 If this was picked up by someone who can do it all themselves, or has a mate who will for some beers then it makes for a good deal. It is good to see the money is still out there to be spent on rare and interesting bike stuff, too.

DT Swiss calculator is good. If your hubs and rims aren't in the database just fire up a vernier and enter your own numbers https://spokes-calculator.dtswiss.com/en/calculator I would say you can't go at all wrong with CX Ray spokes. Round or aero.

Now that is flat! :)

When you have your bike dialled in you could pop over the pond , with pockets full of gels, and have a go at breaking our new 50 mile record ;) https://www.cyclingweekly.com/racing/i-was-comfortably-above-60kph-for-long-periods-seven-year-50-mile-time-trial-record-falls 1hr 30mins for 50 miles...
