Two Things

32" Done Right:

When the idea started looking real concerning 32" wheeled bicycles, I stated here what I thought should happen with this platform. Specifically with regard to wheel axle standards. 

I stated that SuperBoost rear and 150mm OLD front axles should be considered. Some agreed with the rear axle ideas, but most laughed at, or dismissed my thoughts on the front being 150mm wide. 

Well, I feel a little bit validated now due to what I saw and heard listening to the Bikepacking.com video from the MADE Show. (See the written page with the Sunliner 32"er HERE. Scroll WAY down the page!) NOTE - that link won't tell you about the axle spacing. It's only found in the video. 

Anyway, like Daniel from Tumbleweed says, this wider axle in front lends a ton of stability and precision in terms of handling, especially with a load. I experienced this when I transitioned from fat 26"er wheels to 29"er wheels in a fat bike. Those wheels were so much better than most 29"er wheels it was not even a discussion. 

Tumbleweeds are not cheap. But if I were to get a 32"er, the 32" Sunliner would top my list because of this design choice. That and it would make a killer flat bar gravel touring rig. I know someone who might just know about this. Maybe we need to talk....

2012 Salsa Cycles Titanium Warbird

The Evolution Of The Species:

This past weekend marked the anniversary of my trying out the first purposely designed bicycle for gravel racing, the Salsa Cycles Warbird. 

It was August 22nd 2012. I was at a Salsa Cycles demo in the Twin Cities. My test ride was on single track, so..... Not really representative of what I wanted to see in terms of what the bike was capable of, but it was a portent of how many would eventually see "gravel bikes". 

My test rides were on both the titanium and aluminum versions of the bike. Looking back, the original Warbird was analogous to what an "endurance road bike" is in 2026 terms. Maximum tire clearance was 38mm. (!!!) A far cry from the bikes labled "gravel" today which can swallow 29"er rubber with ease. 

It is notable to remember the context of those times though. First of all, it was 2012. The bike was developed over a period of two to three years, so the idea was hatched somewhere around 2008 -2009. Think about this: Gravel racing was a very niche sport. Obviously Salsa Cycles saw the potential for gravel racing to become something more significant, so this bicycle came into existence, but from a lens of nearly twenty years ago, it was a big gamble. 

What was, perhaps, a bit of a saving grace to making this decision was that a Warbird could just as easily have been a cyclo- cross bike, making the "excuse" to buy one a little easier to swallow, perhaps. But this is just my feeling from my recollections of those days. 

Another point: There were no tires for gravel in 2008. Getting Clement ( which became Donnelly after a few years) to jump in with the MSO tire was key to getting the Warbird off the ground, (no pun intended). Remember folks: Tires drive market trends. You can make a "gravel bike", but if Salsa had been stuck putting touring tires in this bike it would have been a big fail. 

Now we have gravel aero bikes, 2.2" wide tires, and carbon everything. But wait! Now there are 32" wheels! (Monster Gravel, right "Bike Rumor? You saw that here first.) So the breed evolves yet again. 

One could say much of this is being perpetuated to keep Gravel™ afloat as a driver in the market. Perhaps this theory has some merit. But I'll say it again: The bicycle industry cannot help itself. Everything it does gravitates toward racing, top level completion, and technical innovations for the sake of technoical innovations. It is painfully obvious that the vast majority of cyclists are expected to hang on to where the industry goes or risk getting spat out the back, (shamed), so.....get on board with the latest! 

Or just 'eff it all' and ride for fun. 

Where will it evolve from here? 

The consumer will decide.
