Removed 1003 from the list, the point still stands though. There is nothing to suggest that through headset cable routing makes for a weaker front end that isn't suitable for mountain biking.

It think he was referring more to the construction of the headset itself. For instance the one I linked looks to be made of a composite. The main concern I would think would be the compression ring that shrinks the 1.5 bearing down to fit the fork.

It'll work, but most of these aren't rated for MTB use. As in they aren't rated to withstand the forces and shocks when you case them or go full send down a rock garden.

So you may be ok depending on your riding.

Didn't even consider this.
Good thinking.

I hope you realize that that is just the upper bearing set.  You need to order a lower one to complete the set.

Since I don't want internal routing through the headset, I ordered this FSA headset for my new frame.

I ordered the regular headset through carbonda. I'm aware that this is just the upper. I have not ordered this one yet, but kicking around the idea. Would use the bottom from Carbonda and possibly this upper if I'm doing the through headset routing. Also got the frame plugs from Carbonda Incase I decide to go this route.

Looking for fork options.
The Carbonda listing shows a 150 fork, but it appears everyone is using a 160. Anyone know if the geo numbers on the site are for a 150 or a 160?

I see the fly bike listing is for 160.....
Thanks

I hate you!  After seeing your posting, I searched the seller's store and saw that they listed small and large frames too.  Because of you, I made the $500 offer, and they accepted.   Grumble, grumble!  Now I will be stuck with one of these frames to build up over the winter.   

Should have gone lower haha.
My frame already shipped and should be here before the weeks end!

If that kinda dorky 70s-but-modern style is your thing and the ~135 mm width works for you, you might also like the x62's sister models (x64 and x63) with identical temples but different front frames. Most of them can by found with both Kapvoe and SCVCN branding; looking to be the same thing. Some also come in funky frame colours (multicolour, gradients, sticker-bomb like prints) and transparent variants.

Now, if that doesn't look like fine (modern) vintage porn?!

(Seriously, I think the light grey/brown transparent frame looks super hot. The rarer "sticker-bomb" prints are fun, too (I just don't have the face to go with them ... or the personality, not sure).)

Bought three pairs of these on your recommendation. If you have a small head like me they are great! Well worth the $3.50.

Also, does it look like it clears 45-50mm tires?

I don't have tires that wide, but this is with 38mm Gravelkings on the rear chain stay:
I would bet they would fit, not sure on how the mud clearance would be though.
