Having not bought a new bike for almost 3 years, I'm finding the market even more confusing these days.
To me, a gravel bike is a cross between a road bike and a cyclocross bike. Able to ride pretty fast on-road, but also able to ride on dry unmade surfaces such as forest fire-roads and canal towpaths.
i think that having looked at gravel bikes, they are almost the sort of bike that I would ride as my main road bike, if only because of the poor state of some rural roads where it can sometimes have a loose layer of sandy, gravelly debris.
once all this lockdown is over, I'm going to have to have a big rethink of my bikes and do some test rides!
Echo that comment about the road bike feeling 'fast as ....' after riding the gravel bike. Mine's 650b 1x, not fast but capable and reasonably comfy over the rough stuff. Bought for exploring and carrying loads, and does both well without beating me up. Road bike for fast blasts.....but sometimes now wearing some gravel bike luggage if need to carry a few bits and pieces on a longer trip. Thinking about it the road bike is disc brake and takes wider tyres, so for me the lines do blur...
Agreed. Roughly they split into;
Mad fast carbon stuff like that cervelo aspero
Down the middle, basically a roubaix bike with lots of clearance, like the gt grade, grail, giant revolt
Adventure bike, so anything slow and made of steel with massive tires and racks everywhere
I go with
- Gravel - for bikes intended to be ridden on American style gravel roads and similar. They typically run 700c, they are almost as fast as road bike, cope with rough roads a bit better but do not usually have huge mud clearance. In the UK they are suitable for most canal paths, unsurfaced NCN's and very carefully chosen bridleways, especially when it's muddy.
- Monster CX - Depending on persuasion; what CX bikes would have become if it wasn't for UCI rules, or like an old skool MTB but with drop bars and no cush. Good mud clearance, large tyres and quite often 650B wheels. Sacrifice a bit of on-road or good "gravel" speed for being able to cope with much rougher terrain. It might not be pleasant all of the time, but big tyres and mud clearance means they will cope with almost all UK bridleways and tracks most of the year.
Both come in lightweight "race", heavier, commuter friendly "all-road" and touring/"adventure" variants with lots of bosses etc. Some can switch between categories by changing the wheels and tyres. Simples
Lol! There's still enough purists out there furrowing their brows trying to comprehend why we even need a sub-category for 'gravel' since apparently people have been taking touring bikes and hybrids off road for decades.
Adding further nuance will probably make a few heads explode...
For the riding I do I need something that will be OK to ride on tarmac for 1-5 miles until I get to the off-road sections of the ride. And those sections are everything from packed down large-grain gravel, deeper loose marble-sized stuff, sand, and various levels of mud from treacle to slurry. Generally quite wide tracks rather than weaving through trees under branches. Also generally quite flat with long swooping descents. I need on-bike storage because I hate riding with a backpack. And (showing my roadie roots) I need mudguards to keep me and the bike less filthy.
The happy medium I've found is a drop bar road bike on 650B meaning I can fit, for example, 47mm WTB Senderos, run them tubeless, and still have room for mudguards. If I was starting this journey again I think I'd probably size down the frame at least one size or find one with an aggressive sloping geo so I could make use of a dropper. And perhaps go 1x. 650B is the key for me - wider tyre, aggressive tread available, lower pressures, doesn't make the road sections tedious. Senderos for winter or the less extreme Byway for the summer seem to be the happy compromise.
The unexpected benefit of this for me is making my road bike feel like an absolute rocketship, even though it's a steel bike on 28s
