I’ve been messing about building various kinds of gravel/adventure/touring bikes for decades and always comeback to the same conclusion that a reasonably light, short travel XC hardtail based build is the best for me. Most of my riding is sub 2 hour rides to squeeze them in around a normal busy life though I manage a longer day out or couple of days bikepacking every couple of months, usually an A to B ride when I’m going away somewhere. For the last 3 or 4 years I’ve had everything from fast gravel bikes, singlespeed gravel, flat bar hardtail with bar ends, more touring type wider tyre gravel bike, and a Rohloff adventure bike build. Of the whole range, my go to bike for the majority of riding has been a steel 29er hardtail frame, 100mm Sid, 100mm dropper post, 50cm non flared drop bars and a 50mm rear gravel tyre with a light 2.1 XC tyre up front. This set up has been used for all sorts of riding, pootling round with the family (I found the drop bars great for when the kids need a push as I can ride closer to them without poking the end of an MTB bar in their ear), fast local gravel, long distance multi day sustrans type rides and even the full loop of the Calder Divide. The same bike with flat bars and bar ends works OK for most stuff but isn’t quite as road useful, is a pain through the many gap stiles on lots of my routes and I get achey wrists on long multi dayers. My frame also means I can fit full guards and a rear rack when I need to which is a bonus. Obviously it’s going to be different strokes for different folks but that just works really well for me. A recent ride, heading up into the dales on what I thought would be ideal gravel bike territory actually turned out to be the final nail in the coffin of the light gravel bike for me and I sold the bike as I just found it too limiting where my drop bar 29er is really good fun.
