Reduced Lightest square taper cranks in the world?!!

[Mickeyspinn]

Extremely light ....my scales are a bit dicky at the mo but they're sub 325g from memory!
I can't remember actual weight but I was going with a 49 42 on these and well below 450 with aluminium bolts. Looks like the inner could run a 38 tooth.
They've seen chainrings and bottom bracket and pedals but not to full torque.
5x130 bcd
Cost me a fortune and I no longer have a road frame worthy of such a treat!
For your neo retro maybe?

These are rather lovely... assuming because of 130bcd they are Shimano size?

They are quite cute not too modern either which is what caught my eye.
Yes they'll fit Shimano rings or basically any rings that are 5x130 bcd I think they're specifically for 9 speed going by bolt flange however you can run run them with 7/8 speed with a spacer if needed.

They're what I would call a spinners crank...they are light so not best suited to big gear grinding legs!
Always fit these cranks with a steel bolt...you can swap them to a lighter bolt if you want to save even more weight once they torqued up!

Even when I was younger I could never do 'dinner plate' chainrings...48/39 sounds good to me...but on bikes which take a brazed on front mech...you can't do a 48 or 49.

I'm an odd one I kind of mix it up a bit!
My touring bike is a 42 49
My fun bike let's just go somewhere is 39 53
And theres other strange stuff ..one bike has a 64
So you can't get enough drop on the braze on mount to go smaller rings?

50 is the lowest you can go with a braze on for your larger chainring.

Just another 2.5mm lower and you'd probably be able to run a 48! The fettler in me says there must be a way!

Easy! Remove the braze on front mech tab and get a band on front mech...so as low as you want...but???

There you go! Solution found

It is 'a' solution but not one that I would use on a beautiful Italian Columbus SLX frame...my touring bike has a 44T large chainring but the front mech is band on and not braze on...Horses for courses etc.
