FS: 50.4bcd 5 vis CNC chainrings compact doubles for Stronglight, TA and other cranks

[Edit 05/07/2024: I added a triple and a 1x narrow-wide for sale to this thread, but it seems that I can't change the title of the thread anymore]

Hi there,

I still have some chainrings left which I have made in the past two years using CNC. They are all meant for 50.4bcd cranks (Stronglight 49D, TA Cyclotouriste, etc.), made from AL7075 with CNC chainring bolts made from stainless steel. Some are replicas of well known (and pretty rare) French chainrings and some are designed by me. Most of them are 46-30T doubles, the Stronglight Diamond and the one I call Narcisse (has nothing to do with the French constructeur) are 46-28T. I also have one triple (TA Adaptateur, 46-38-XXT, XX can be any standard TA Cyclotouriste small ring) and one narrow-wide 1x 34T ring for 1x setups (up to 12 speed). The teeth (except the ones on the 1x ring) are not optimized for modern setups (in case you were wondering). The rings are slightly polished and waxed by hand to remove most of the machining marks, but some minor machining marks are still visible. The 1x rings are silver anodized.
I have some other CNC projects in mind, so selling these rings will help me a lot to finance future CNC projects.

Doubles. From top left to bottom right in the first picture below:
1 - Simplex Touriste 46-30T, 195 euros per set
2 - Cyclo Rosa 46-30T, 215 euros per set (only one left!)
3 - Stronglight Diamond 46-28T, 225 euros per set
4 - "Herse Verot" 46-30T, 195 euros per set (only one left!)
5 - Hermes 46-30T, 195 euros per set
6 - Narcisse 46-28T, 215 euros per set

Triple. Scroll down for the pictures:
1 - TA Adaptateur 46-38-XXT, 290 euros per set

Single 1x narrow-wide. Scroll down for the pictures:
1 - Herse Verot 34T, 90 euros per set

I am based in the Netherlands but shipping to anywhere in the world is not a problem. Shipping to anywhere in the world is about 15 euros and I can ship it as a gift (so no tax). I accept PayPal (friends and family please or with an extra tax).
Let me know if you have any questions.

I forgot to mention that tracked shipping to the US is pretty affordable (around 15 euros) and tax free (will be sent as a gift).

These might be the prettiest 50.4 BCE chainrings I’ve ever seen. Plus the 46-30 is a great set up for a double particularly if running a rear derailleur that is limited in how large of a free wheel it can deal with (like a campy).

Thanks! I run these rings on all of my bikes and they are great with 14-26T freewheels or something close to that.

Checking in to say I bought two sets of the Simplex chainrings when OP first started making them. I havenít gotten around to mounting them on a bike but the quality and finishing is top notch. Happy customer over here, you wonít be disappointed.

Thanks! Nothing in 130BCD, unfortunately. I was thinking to make rings for 116BCD 3-arm cranks (TA professional) which will accept smaller BCD as well so you could run them with a compact double setup.

Thanks for your feedback! Much appreciated! If I am not mistaken, those were Stronglight Diamond not Simplex...

I've added a triple and 1x ring (see above) to this sale thread but also realized that I can't change the title of the thread anymore.

The Stronglight Diamond rings are among the most beautiful rings ever made IMHO

Count me as a very happy customer! Yesterday I installed a set of Alex’s Herse Verot rings on some Stronglight 49D arms and mounted them on my Mercian. Went on a pleasant test ride this morning. Excellent stuff! Thanks, Alex!

Thanks Neal! I am glad you're happy with the rings! Your new setup looks amazing! Send us a few pictures of the whole bike
