Entry level chainset but very good quality for price, I have used this chainset on budget builds and after 2 years still going strong

Stronglight are one of the forgotten manufacturers but they are still hard at in the background

Chainrings: CNC machined Dural alloy.

Very good quality front crank single chainwheel 44 or 42 tooth, integral chainguard, 1/8 pitch on crank. Nice sturdily cast crank arms with nice Sturmey detailing.
I use these on customer builds to great effect.
Well made and well finished for a good price

New fixie style fron crank from Sturmey archer to compliment the S3X set up , sytylish heavy duty chainring with 170 cranks
