hmm... since both you and [MENTION=426321]Chombi1[/MENTION] gave the same answer, I'm going to assume that someone has actually tried it. :)

In a more practical sense, I do think it's an oversight in marketing to not have a visual cue to the wonders that lie inside the shell. A BB cutout would be a necessity to get the full value of this unique axle. Of course, you've got to leave the sleeve out, so you'll be cleaning it frequently.
With a Phil BB, you can see the splined retaining ring.... although no one knows if you've got the steel or titanium axle.
Wiith the Campy SR titanium axle, there was a version with a threaded stud on the end, which means that it is visible externally (because you won't install the heavy dustcaps after paying for the full SR group). Maplewood bike shop in the St Louis area has a Raleigh Team on display with just this arrangement.....

I think this was the first time I've seen this type of axle in person.

Simplex middle 1950s-
No conventional brake levers but rather one pulls back on the handlebar to stop. Various versions made.

OK, I give up. That's a stumper. What is the purpose of this 3 part water bottle? I'm thinking it isn't supposed to be used for water....

I think you answered your question. Lol

Same company made conventional and aero bottles along with cages for cycling. The trio set is 'esoteric'.

That's pretty wild! Any idea as to whether it worked?
It kind of reminds me of some old bone shakers where the handlebar was twisted (rolled on it's axis) to wind up a cord that pulled the brake block against the rim.

That's just wrong! A quick stop has you pulling the bars as inertia pushes you into them. :twitchy:
I suspect amazing stomach muscles were in order.

My guess is it was for different dilutions of amphetamines ;)

Circa 1950 Hercules Herailleur. The first indexed derailleur according to Frank Berto.

it bears a strong resemblance to a tennis racket holder shown in a Bike Warehouse (later Bike Nashbar) catalog in the early 80's.
Here's the catalog page.....

and here's the detailed bit about the racket holder....

don't ask me why this sort of weird stuff sticks in my memory. Seems like I could be making better use of that limited resource!

Ding ding...looks like a winner.

and just to show off how many old catalogs I have, let me show you the 1976 Schwinn catalog that features the same gadget...

I did not know that Schwinn sold the French Wonder Light headlight/Flashlight back then, as a "Schwinn Approved" item.. I had one when I was in college and really loved its versatility, plus I loved the clean white cases they had that seems to be giving an Apple-like flavor to the then unique light, years before the trend. Fits my shirt pockets perfectly too. Ther look quite primitive now though, especially with its chintzy looking incandescent bulb that had only a fraction of lumens of what LED headlights now have....

The lighting kit second from the upper left is the very one I installed on my Winchester 10-speed when I was 13. Apart from raising and lowering the saddle on my Sting Ray, it was my very first foray into bike wrenching, and it worked great from the very start. An auspicious beginning for a completely inexperienced bike mechanic. :) I tried to get my dad to help me install it, but he just handed me the toolkit and said "Looks pretty straightforward; see if you can do it yourself." One of the many favors of omission he did for me while I was growing up. (I had six siblings, and dad had hobbies and pursuits of his own.)

Anyway, that kit lasted through at least nine years of night riding, on three different bikes; all the way up to the end of my college career.

That's a nice memory, [MENTION=280039]Lascauxcaveman[/MENTION].

I remember when that tennis racket clip was popular. I saw a lot of them.

I have about 5 NOS Tennis Racket mounts like that buried around here somewhere.

I think this counts, Mavic electronic shifting system. My uncle gave me the complete setup which he got from the original owner, said it worked fine when he removed it to sell his bike. The instructions also came with it and look daunting to say the least.

^^ Brave souls. I have lots of patience but think a Mucktronic would ruin my day.

Here's an shopworn but unlaced fixed gear drum brake hub with replacement pads. Nickel plating, circa 1930.

Here is a fun one. :D Though granted, not C&V

Tennis/Hockey clamp. ;)

These are still fairly common in the Netherlands as field hockey is a common sport in wealthier areas. link + eBay example

The oval rings added to the 'eL' cranko are over the top!

I used Weyless hubs on my race wheels. Nice.
I still use the front, but no longer ride 120mm rear bikes, so the rear is collecting dust.

Ok, OK, [MENTION=350383]crank_addict[/MENTION], either you're photoshopping us some sh#t or I took too many drugs tonight. :lol:

It's a deep conspiracy, I tell ya, wheels within wheels, man...
