Gravel bike with road tires?

2583 Views 51 Replies 13 Participants Last post by  fiziks
Unlike some of my friends, my wife is not going to put up with a garage full of bikes. My road bike is aluminum, and I'd like to upgrade to carbon and higher end groupset. I'd also like to get into gravel. Anyone get a gravel bike and have two sets of wheels, one for road and one for gravel? I'm looking at a carbon bike with GRX800 2x12.

Absolutely. It's very common. And a great compromise to having two bikes.

Also be aware, many road bikes nowadays fit quite wide tires. If your 'gravel' is just hard pack rail trail type stuff you can easily use a road bike. Or an endurance bike.
The new Canyon Ultimate will fit up 32 mm tires

I'm looking at doing the Filthy 50 in September. But yeah, I do hard pack all the time on my road bike. I was considering a road bike and getting wider tires for gravel, but gravel bikes seem to be quite a bit cheaper for the same kit. i.e. Carbon road bike with Ultegra groupset for $5299 (or 105 groupset for $4699) vs Carbon gravel bike with GRX800 groupset for $3499 from same manufacturer.
I have two wheelsets for my gravel bike - 28s on one, 40s on the other. I have a few other road bikes, but do occasionally ride the gravel bike in street form for certain rides, e.g., slower, more casual rides, in-town "doughnut ride", etc.

My gravel bike is all carbon, light(ish) at 18lbs., etc., It's a nice bike. But, it's still not a road bike. The longer wheelbase, more upright position, wider bar... I didn't expect to feel the difference, but I do. It's not a deal-breaker. If I had one bike, it'd be a full-on gravel bike - not a road bike that can handle wider tires or an endurance kinda road bike - and two wheelsets.

Shux, no problem riding wide tires on the road. I've a bike with 42mm tires which I ride with no issues. Road tires, not knobblies. I run Herse Baby Shoe Pass tires and they're great and there are other brands that I can't comment on because I haven't tried them. And there are those who are running wider tires than my 42.2, 48's aren't uncommon.

Jan Heine even claims that his knobblies roll almost as well as road tires on pavement.

A garage full of bikes is always the best option. However, if it is not possible to "fix" your wife two sets of wheels on a gravel bike is a reasonable option. Even though I have a few road bikes I still have two sets of wheels for my gravel bike; one for road and packed surfaces, and the other for the rough stuff
My Alu gravel is 5 lbs heavier and about 1/2 to 1 mph slower than my carbon road bike. If I were planning on only one bike, the 2nd pair of road wheels would be a narrow and fewer spoked carbon wheel to save weight. I don't need the strength of a wider and heavier wheel on asphalt.

Rene Herse tires are great if you're flush. For less $$, Panaracer GravelKing slicks roll nice and are a great bang for the buck.

I agree.

I'm running those on my 700c bikes, 700c-32mm and they're great. My wife has a set of 700c-32mm Herse tires on her bike that I'd like to swap onto one of my bikes to do a direct comparison, but the Missus says that I need to stay away from her bike.

Wider tires not only improve the ride comfort, they also corner better.

And the older I get, the more important a non-jarring ride is.

Yep.
Wide Rene Herse type slicks will work well off-road in almost anything apart from mud and very loose mushy gravel.

So, what gravel bikes make good road bikes? Or are gravel bikes just road bikes with wider tire clearances (aside from the groupsets - I know they are different)?

Gravel bikes are generally a little beefier to handle the rigors of........dirt and gravel. The GT Grade probably comes closest to your typical endurance road bike:


Keep in mind that most endurance road bikes now have room for wider tires and can do light gravel and dirt roads pretty well.

Gravel bikes typically have a lower BB and slightly slacker HT/ST angles.

Hmmm. Maybe slacker than a race bike. Not necessarily slacker than and endurance road bike, though I'm sure that varies. Gravel bikes will generally also have a longer wheelbase.

Pretty much the same bikes, unless one is looking for a reason to get another bike.

Not exactly. A gravel bike still has room for even wider tires and a longer wheelbase which adds stability.
