Re: Seraph Bikes Superlight 836g X68 - Alternative to SL8 Fakes?
Received my frame today. Ordered from tantanbicycles.com for $719 -$10 coupon 'ROADBIKE' + $180 shipping to Florida. Ordered July 14, it shipped on August 20, then handed over to UPS in California on Sept 9, ground shipping to Florida and received Sept 15. I was not billed for any tariffs.

I got the chameleon white and it has a nice pearlescent shine to it. Brake mounts, BB face, headset bearing cups all look fine.

Weights:
878g 52cm frame, derailleur hangers, no axles
422g fork, uncut
340g 400 x 90 mm handlebars
154g seat post and saddle clamp

I'm going to build it up with:
$1,087 Ultegra Di2 R8150 groupset
$338 XCADEY Ventus carbon crankset power meter
$608 EliteWheels Edge 50mm deep
$300 other parts
$889 frameset
===
$3,222


The BB and mounts look fine, but they haven’t been faced at the factory. You can see this on the BB where the paint goes right up to the edge of the shell. On the original SL8, that surface is properly faced, leaving a ring of exposed carbon.

I eventually had my mounts faced because I just couldn’t get the front brake caliper set up perfectly—it always rubbed once torqued down. After facing, everything aligned properly.

It really comes down to luck—you might have issues, or you might not. Even some big brands don’t factory-face their frames. It wouldn’t be such a problem if disc brakes didn’t need to be set up so precisely—dead center, level, and perfectly upright!

Re: Seraph Bikes Superlight 836g X68 - Alternative to SL8 Fakes? Not looking as bad as other ones I seen where the paint covers the whole of the BB sleeve. Looking at a genuine SL8, the Specialized bonded BB threads don't have an outside lip on the sleeve, so when the BB gets perfectly machined you can see the bare carbon. On the X68, to get to the carbon you'll have to go beyond the alu sleeve lip. I may be wrong, would love to see a frame after being faced
I'm waiting for my X8 details to be finalized. Still not sure to get it on that lovely British racing green or bare carbon and get creative. Either way I'll be gently facing the BB and go at it on the brake mounts with diamond cutting bits for the facing tool
