Don't over-analyze the geometry. First, I can tell you with 100% certainty that the reach numbers on the Diamondback are incorrect. There's no possible way they are that small, especially given the top tube and seat angle measurements which look more in line with 'normal' geometry. Diamondback is really screwing themselves by having the frame reach numbers (probably the most important number) being wrong.
All of those 3 bikes are good. I would just pick the components you MUST have and the color you like the most. One thing about the Haanjo Comp Carbon is that it has mechanical disc brakes. I don't think I could ever go back to non-hydraulic brakes. The jump to the Haanjo Trail Carbon gets you full hydraulic brakes, very nice (and fast) tires, mostly Ultegra vs. 105, and a marginally nicer crank. I'm a big 1x fan, but there's no reason to abandon the idea of a 2x bike. Swapping the 36 small ring to a 34 and putting a different cassette on the back (11-34 or 11-36) would give a super low gear range and stay within the specs we know work for a 2x system using a GS road derailleur.
Is stand over really important to you? It's a tall frame, but I can't say I would ever look at stand over height when choosing a frame.
BTW - The Haanjos all have a 3rd bottle mount under the top tube. Also, for the money, I think the Haanjo Comp is the best specced bike for the money. Huge range cassette, great tire clearance and a fantastic spec. Apex 1 works really well. Over time you could probably swap out a few parts to save weight.......it may not be a significant upgrade from your current ride though.
Dangle here is where I am at and then maybe you can help me. My Tamland has some pretty decent components on it. The kicker is the starting weight of it is 25.1 lbs without pedals for a 56 cm frame. Add pedals/tools/trunk bag/2 water bottles/and a frame bag with food and now you are talking probably 28-30 lbs. That makes for a tough climbing bike. The bike I want to buy is/should/will be right around 20 lbs. or a hair over is what I want to buy. If I remember right Shoota on here spent some bucks to get his bike(Tamland) 2 lbs. lighter and felt maybe in the end that it wasn't worth the cost. This is why I am looking for a carbon or ti bike but want to get the best bang for the buck in a bike. Now too concerned if the components are much better but just wanting a lighter bike. I have lots to learn yet gravel riding/racing. I thought the stand over height was very important as if you run into an emergency situation you want to be able to touch the ground easily with your feet. I though that would b difficult if the stand over height was too high and you couldn't touch the ground while sitting on the seat. The Hanjo stand over height does look taller than the other 2 as the 53 cm is the same as the others in 56 cm. Color is no big deal/deal breaker for me as I haven't really seen a gravel bike that wows me. It' going to have dirt/dust etc. on it so no biggie about the color. Any help is greatly appreciated. Thanks Zman
If it was easy it wouldn't be a memory. You just hope you don't have all your memories in the same ride. been there dun that Zman
