Not necessarily on-topic for this site, but I know alot of people are doing builds here in the US.  bikecloset.com has some killer deals on SRAM components, especially Rival ... everything except batteries, cassette and rotors for $460.  Check their "Builder's Corner": https://bikecloset.com/product-category/builders-corner/

Note they have 2 different FD's, one for $59, one for $129, just a head's up!  I have no relationship with them, but have ordered from them a few times and they've been perfectly reliable.

Posting in cyclocross thread since I think that’s closest to what I’m looking for.

I have a Black Mountain Cycles MCD and am looking to pare some weight. Although the welded crown forks are very cool, they’re pretty heavy too. Anyone know of a good source for a full carbon replacement fork? It’s a straight 1.125” fork with 50mm offset and 410 A-C. I don’t mind coming a bit short for the A-C measurement but I’d obviously like to stay within 10-15mm.

SP Cycles makes one that’s pretty close: US $108.00  20％ Off | Spcycle Full Carbon Gravel Fork 1-1/8 Straight Tube Disc Brake Forks 700C 650B Lightweight All Road Gravel Bike Fork

That one is a little short at 395mm. There are a few available through conventional channels, but $500 for a fork is a little rich for me! I’d pay that for the Ritchey if it weren’t too too short 386mm if memory serves).

Mostly wondering if anyone has any other suggestions or if that Spcycle is my best bet?

Second post like this, but thought a separate thread would be worthwhile. Anyone with experience with the Eglath? I think it’s a really good looking frame, listed as their all rounder but not a single mention on the forum. Maybe too milquetoast … not light enough, not aero enough?

Anyway, thoughts or full build pics would be appreciated!
