I guess the GR029 is considered more of a CX than a gravel frame so I'm posting this warning here.
You may purchase a GR029 from a seller than includes axles, but if you don't, you need the specific axles, particularly the front, that's made for this frame.
Seraph is clear that the price on their website doesn't include axles. That's fine. They're not clear that there's no chance that any other axle that you already have or might buy, will fit that front fork. That's not fine. I'm out weeks waiting for a second order for the axles because I didn't know that I had to have the axles they sell for this frame.
Come on Seraph, be clear...better still, just include them and raise the price $34. Better STILL, lose the proprietary bolt-on front axle and put a threaded insert into the fork.
If I knew then what I know now, I'd have ordered the axles...or some other frame, more likely.
Don't make the mistake I did and order a GR029 without buying the axles.
