Just took a look. For the price the weight is tempting.  I don't see any direct mount cranks. 

Well i have to say this has been an extremely helpful thread. 

I think Im going to pull the trigger on the AliExpress $85 light weight combo package.

its not that much cheaper than the Shimano setup i listed ($113 after coupon code) but it is lighter. 

As long as you all think I wont have any issue going with the AliExpress over the more industry standard Shimano im going to go with it.

Thanks

 

Thank you all very much for your help.  you have saved me countless hours of research. 

Side question.  where in this description can you tell that this crank/BB combo is compatible with a BSA threaded BB Socket?  For some reason all these different BB's is very confusing to me.


Material: 7075 T6 CNC aluminum alloy
Size: 30T 32T 34T
Crank size:170MM
Offset: 1mm and 6mm
Weight: 760 grams (including the axis)
Color: Black Red Blue
Suitable for GXP XX1 X9 XO X01 crankset
Package Include: Crank x 1
                             Chainring x 1
                             Axle X 1
                             Crankset screws x 3
                             Crank Screw X 1

I've seen that same setup on eBay. I assumed it wasn't compatible with the 73mm BSA socket on the frame I purchased.

I think I need a 170 mm crank. I'm 5'9 with a 30.5 inseam. Most of the things I've read about crank length seem to be very subjective but I believe I fall into the shorter 170mm category over the longer 175mm.

Awesome.  So for $123 I can grab a BB, CR and Cranks.  That is well within my budget.



In your opinions would this be comparable/compatible?

Wow,  I haven't even looked at cranks yet,  Im glad I posted here.  Im trying to build this on a budget, ill start looking at cranks now. 

Thank you

Hello All.

Ive been lurking on this site for a bit now.  After doing a good amount of reading I finally decided to pull the trigger on a Carbon 29er Hard tail. 

I currently ride a 26" Merlin XLM Ti frame.

The frame I purchased says Bottom bracket BSA 73mm. Bottom Brackets have really changed a lot since I built up my Merlin. 

My question is will this bottom bracket work with my frame?

If not can you make a recommendation?

Thank in advance for the help.
