Diamondback Haanjo Carbon Comp Sizing question

Hi Guys,

 I am thinking of buying the Haanjo Comp Carbon, I am about 5.9 with a 31 inseam and ride a 54 on the road, so I was thinking of getting a 53 (which is rated as having 54 TT), but talking to one go the DB reps, he said that these bikes have a short reach and that I should size up and go with a 56, which sounds contrary to what I would do, but without being able to try one before I buy it, I am wondering if anyone has any insights?.
Here is the Geo chart

Thanks in advance

The DB rep is giving you bad advice. I'm 6' with 34" inseam and found the 56cm Haanjo to be a good fit when I test rode one. I didn't really notice the short reach, but I did notice that the standover height is almost 33". Get a 53cm, just like the DB size chart recommends.

Ya--agreed with the comment above: not sure if the advice you got is so great.  I'm 6'1'' and bought the 59cm.  I found it to be too big for me. I would have gone down a size.  Having said that, it was an all right size for gravel riding, but it was a bit unwieldy when I took it into single-track stuff.  

Final thought: I think these go out the door with a fairly long stem and a set-back seatpost, and those two things are easily swapped out.  But I think they go out the door running on the large size, not the small.  Sold mine, partly for that reason.  

Hope that helps!  

P.S. I've seen a few Haanjos on eBay lately.  Might be worth a look. 

What bike (specifically size, measurements) do you currently ride that fits you well?

The fact that the Haanjo's reach numbers on the website geo chart are wrong doesn't help them either.

I don't have a Gravel bike, but for reference I ride a 54 CAAD 10 on the road and my MTB is a Medium Niner.

Do you know how long of a stem you use on that CAAD 10 and how many/much spacers you have under the stem?

I believe (though I am 100% sure) that my stem a 100 and I have 4 spacers.

I'm sitting on a phone call and pulled up bikegeo.net to play with numbers.

If your stem is a 100 and you have 4 spacers that are 1 cm each, the 53 Haanjo will fit the closest. If you also go with a 100mm stem the handlebars would be ~5mm closer and ~5mm higher than your current fit with one spacer. If the spacers are smaller than 1 cm, it changes. If they are 5mm each, then the CAAD10 is a little bit longer and you would need a 110mm stem on the 53 Haanjo and no spacers to be the exact same length/reach to the handlebars, but you would be ~15mm higher on the front end. That's also assuming the top caps are the same height between bikes.

When the angles and head tubes are so different between bikes, it's way less than an apples to apples comparison, so top tube (and even reach alone) don't tell the entire story. I'm sure somebody could poke holes in some of my numbers, but I think choosing the 53 over the 56 probably makes the most sense, especially if you're comfortable on a 54 CAAD 10 with a 100mm stem that's raised up a little high.

The thing that hurts the Haanjo is a fairly high standover. That's one of the dumbest ways to size a bike, but the Haanjo is a bike where that has to be taken into consideration. The 56 Haanjo is something like 50mm/2in higher than your CAAD10.

I'm also thinking their reach numbers are closer to correct now if not spot-on. There was a long time that they were way off. It's a frame with a pretty short reach relative to its road brethren. And also tall which makes it harder to fit people properly.

Edit: I originally wrote 54 instead of 53.

I have two Haanjos, a 2015 Trail and 2017 Trail Carbon both in a medium (53). I'm 5'8 with a 30' inseam and I think this size fits perfectly (I bought a second one after all).

I've ridden a lot of gravel and raced them in cross and the geometry somehow works both for long endurance rides and American style cross courses.

As noted the standover height is pretty high but I have a bit of clearance (not much). I run a 0 degree 90mm stem (they come with 90mm 6 degree rise).

At your height I can't imagine going up to the next frame size would be a good idea.

Thanks for all of the responses.
I have decided to go with a 53, I hope to get it in the next few days, we shell see how the fit goes.
I hope that I made the right decision.

I am guessing you made the right choice. I am 6 ft. with 34 inseam and  ride lots of 57 cm Lemond road bikes. I went to my Raleigh dealer tried standing over a similar bike to my first Tamland 1(guessing the bikes are close as they are brother/sister Companies) and bought the 56 cm at my end. Fits me perfect. I am since bought a Roker Comp 56 cm going out to try that out now.

Good luck

What? Really? Is there an updated chart somewhere, or calculator you can plug in the other measurements into?  I was looking pretty hard at the Haanjo's, but the short reach made me take them off my list.

Devinci Hatchet. Super long and low.

The Hatchet is a beauty indeed!

It is long. But...

I'd love to know the BB drop #... since the BB height (the # given in the geo chart) is dependent on tire size (none is given) and these bikes have a wide range of tire options, it would be good to have the BB drop to compare 'apples to apples' if you will. I recall someone in another older thread asking the same question and never saw an answer.

I'm similarly curious about the fork offset. They give the head tube angles - but without a fork offset # there is no way to determine the trail. This will give some indication as to the overall handling. There are many paths to a nice riding bike and I'd love to know more about the geometry.

Lastly, since the OP's question had been answered/decided I thought I'd ask about the Hatchet here since the other thread is 5 months old... sorry about the brief hijack.

CXmag mentions the large having a 70mm drop.

You could work out the fork offset, doing some geometry calculations, along with other geo-chart dimensions. Probably easier to ask a shop in the know.

Thanks for that reference. 70 seems in line with other gravel bikes (except the Specy Diverge). \n \nI was looking at those #s to try and calculate it, but I don't think there is enough info in their geo chart. I could be wrong, and if there is enough info, the math is well beyond my skills. \n \nI actually sent a note to Devinci asking them. ;-) \n \n \n \n

They are finally updated. The numbers appear to be correct now.

Even with the updated numbers, the 53 still looks too short, and I'm right in the middle of their suggested height range.  My current bike has a 378/563 stack and reach (vs the 371/570 Haanjo), and even with a 110 stem it feels ever so slightly cramped.  Do these fit different than the numbers suggest?

I don't know what that means.

Keep in mind that handlebar reach and shifter reach also have to be considered. Some handlebars are longer than others. The 685 hydro levers on the aluminum Haanjo Trail  vs. the 105 mechanical levers on carbon fiber Haanjo comp will give you nearly 10mm of extra reach. There's several factors at play.

Plug in the numbers for both bikes at http://www.bikegeo.net/and look at the final stack and reach numbers at the stem to figure out how close you are going to get.
