Diamondback Haanjo BB?

Planning on buying these for myself and my wife. If I needed to swap the FSA crank with a SRAM/Shimano, what BB would I need? Also, would this be able to take a JIS taper BB in case I decide on a Velo Orange 30/46 crankset?

The spec sheet says 

Cranks	FSA Gossamer Cross BB386 Evo, 46/36T
Bottom Bracket	FSA BB386 EVO

This is the BB that goes with the 30/46. I guess it's a screw type and won't fit? If not, how difficult will it be to put on a SRAM crankset?

 

Thanks.

Press fit versus threaded, won't work without adaptors if there are any made. Have you thought about just changing the rings?

I have, but the smallest ring I can go to is 34. Not a big help.

Maybe a Roadlink and a 11-40 cassette is the way to go.

How much do you need a 46? Could you get by with a 42 instead?

This is a nice crankset in 24mm spindle with 28-42 rings:

That's the solution I used -- Wolftooth Roadlink with an 11/40 cassette. It woeks extremely well. Did have to lengthen the chain though. You could also install a 34 chainring -- which would give you a 34/40 low hear --- not much different than the 30/36 you are aiming for. Frankly, the 36/40 is working for my 73 year old legs on some steep NH hills. It's way easier, and probably less work and expense to use the 11-40 cassette and Wolftooth Roadlink, than to try mucking with finding a BB adapter and switching crank sets. I'm not a big fan of press fit BB's -- too many different incompatible bb standards. But most new bikes these days use them to improve BB stiffness and reduce manufacturing costs. Hope this helps.

I swapped my FSA crank out for a compact 105.  I used a Shimano 6800 bottom bracket with standard English threading.  I know the Diamondback website says the bike comes with a BB386, so I'd recommend taking yours apart (before you buy new parts) and see what is really in there.  My 2016 is English threaded.

You mean you could just put on any BB that has an English thread?

Thanks.

Again, would that need a BB change? The 'types' of BBs is beyond my level of comprehension.

Just ordered from Comp Cyclist, and they have agreed to put on a 34. 

I think the 40 cog cassette might be the easiest solution. How is the shifting with the Roadlink? Any deterioration after adding the Roadlink? Where did you order the cassette and Roadlink from?

Thanks for the help :-)

The Roadlink is very easy to install -- but you will have to lengthen the chain. I replaced the stock KMC chain with a SRAM 11 speed using the the full length of the chain out of the box. Once you tune the inner and outer limit screw and adjust the tension on the rear der. everything shifts smoothly and perfectly. Although I don't recommend it, I can even run the 46/40; good to know you wont trash your rear der. if by chance you shift to the 46/40. On the other extreme, the 36/11 also works, but the chain is a bit too slack. The 34/11 with the long chain may cause some problems. You might want to shorten the chain if you are running the 34. Frankly, there isn't much difference in gearing between a 36/40, and 34/40. I would suggest trying out the stock 36, before switching to the 34. I purchased the Roadlink on Amazon: https://smile.amazon.com/Wolf-Tooth-Components-RoadLink-Configuration/dp/B013ZTTEJK/ref=sr_1_1?ie=UTF8&qid=1468931383&sr=8-1&keywords=wolftooth+roadlink . There are excellent installation instructions and gear range tables on the Wolftooth web site.

\nThe Botton bracket that comes in the bike is not a square taper spindle. \n \nThe BB listed in the specs is an English threaded type (how it fits into the frame), so you should be able to use the crank you want, and you will need to replace the BB.

Also, check Wheels Manufacturing for potential bottom brackets and/or adapters.  I've got a Ridley w/ a 386 BB and it uses a Shimano BB for use w/a 24mm spindle.  But usually they are for a 30mm spindle.  I'm not sure they make an adapter for a threaded BB or not.

One of my buddies used the 30mm to 24mm adapters on his Diverge to use an Ultegra crankset.  He bought the Cx crankset, 46/36, and then switched out the 36t for a 34t.  In the back, we both use a SRAM 11-36 11-sp.  We both can get by with a B-screw adjustment but I put on a RoadLink anyway.  But with the new 11-40 mountain cassettes are a possibility.

I think Shiggy might be correct.  The BB on the carbon models is threaded cups for a 386EVO crank.  And on the lower model it appears to be a threaded BB.  I think we can infer that is the the same with all models?
