S3 Ultralight steel bicycle frames by Rodriguez Bicycles!

True Temper S3 is the same strength formulation as their OX Platinum tubing but made oversized,then shaped and ovalized to maximize its strength even further. Think of a car's fender. Without the shape to it, the thin metal would be more easily bent.

Because of this shaping, we can use even thinner tubing to get the same performance as an OX Platinum frame with thicker tubing. Rodriguez S3 frames have a well deserved reputation as excellent climbing bikes. A Rodriguez S3 frame rides so lively that it will convert a carbon fiend in one ride! The ovalized shape of the over-sized, thin-wall down tube provides the lateral rigidity that you'll need to climb any grade!

Weight
We've built S3 frames all the way down to 2.2 pounds! Wow! That's a light frame. I've yet to weigh another frame on our digital scale that is that light, and I've had manufacturer reps bring in some very expensive European racing frames. The look on their face is priceless when they find out that our $2,000 frame is lighter than their $6,000 frame.

Anyway, in a medium size (5L) you can expect a Rodrigez S3 frame to weigh in around 3.0 pounds (2.6 with the ultra-light upgrade). That's an extremely light weight considering the fact that it's a verified weight (not just telling you what you want to hear). S3 Steel is probably the most remarkable frame material for making a bicycle that has been developed.
