Greg’s Frame, featuring all kinds of moderately boring stuff

This is going to be a bit discombobulated, because I’m leaving for the track in about 10 minutes and I’m going to try to write this entire blog post in that time. Proofreading is for sissies anyway.

You all remember Greg. The big dude who breaks things. I posted about his fork just a few days ago. While the fork featured a lot of new (if not perhaps earth-shattering) features, the frame is, like Dean’s, pretty boring (hah! Got in another dig at Dean!)

It’s a 29er, it’s a singlespeed, and it’s got fairly conventional angles and geometry numbers (though the chainstays are on the short side and the head tube is on the long side).

But the kicker is this – the frame is insanely beefy. To whit:
-Supertherm toptube and downtube (32 and 38mm diameters, respectively)
-Beefy Deda s-bend chainstays
-Super burly (heh) 19mm seatstays that I got when Burley Designs stopped making bikes.

For those who don’t know, Supertherm is just True Temper’s brand name for their OX platinum tubing, drawn thicker for BMX/cargo/stupid bike use. Where most OX platinum tubes have wall thicknesses (at the thick sections) of .7 or .8mm, Supertherm is 1.0 at the thick sections and .7mm in the middle/thin portions – meaning that it’s lighter than straightgauge (which is typically .9mm/.035″), as well as a lot stronger.

The bottom line is that the bike is a total tank – it weighs 5.25# (or, well, it will when the sliders are actually bolted in). Then again, there are plenty of much smaller production bikes that aren’t at all intended for big people to ride drops that are similar weight. So it’s all relative. I’m betting it’s not any heavier than Greg’s old frame, actually.

Apologies for the crap photos. We had a high of something like negative 6 here yesterday and my motivation to go pose the bike in the snow was pretty darn limited.
