Classic 50.4 BCD cranks, like the TA, Stronglight 49D, and others, are still sought after by randonneurs and cyclo-tourists. These cranks offer tremendous versatility since chain rings from 28t to 62t fit. They are also light and have narrow Q-factors, or tread.
While the Grand Cru 50.4 Crankset looks like a classic, we have made several important improvements. They are cold forged from 7075 aluminum alloy. The rings are thicker so they don't flex as on classic cranks. The outer rings have modern shifting aids such as ramps and pins, so shifting performance is much improved. All stainless hardware with allen head nuts/bolts. Includes aluminum machined dust caps and BB bolts. Dust caps function as self extracting crank hardware.

Awesome works great on my new old French Unic-Sport!!!
Killer crankset. I was looking for better climbing gears and more versatility to tackle light touring and long days in the saddle across varied terrain, and this thing nailed it. This replaced an old Shimano crankset on my Cross-Check and the difference is night-and-day. The aesthetic is on-point, build is quality, and the stock gearing is perfect. I have it paired with an old Shimano Tiagra FD - the shifting took a little getting used to as it's quite a jump between chainrings. The chain slipped off a couple times early on but it's mostly been a matter of getting used to using to the shifting. I'm sure going friction would help, but I wanted to keep as much as what I already had. All in all, very happy with this crankset and highly recommend!
Love love love the look, the default chainrings and tooth counts, and the narrow Q factor. I use these with slightly narrower than recommended BB spindles (phil wood 116), but I still have plenty of frame clearance.
One slight issue is that, when paired with a SRAM Rival FD, there is a chance that the derailleur cage rubs the crank arm when in the smaller rear cogs and in the big chainring up front. The cage has some bend to it I think as part of "yaw". I can thankfully address it via trimming with friction shifting. Probably wouldn't be as much of an issue with traditional FDs, but still worth noting
I have it on three bikes and planning it for two more!
I updated a Peugeot
To get the lower gearing for the steep hills
The looks fit the bike from the 80s
