I've almost finished my SPCycle GR058 build. Frame took ages to come and then I ordered the wrong type of T47 (external when I needed internal). Anyway, it's basically ready for a shakedown in time for the better weather. Playing around with fit so ignore the swan-neck stem and upturned hoods. I hate the size of the hydraulic hoods vs the old Ultegra 6800 ones I'm used to.
But the bike is fine, overall. I thought toe overlap would be a major issue, but it isn't really (might be in winter mode with full 'guards on). It came out at 8kg without pedals. I've ordered some nylon M5s as there are so many (already rusting) bolts hanging to the frame that I'll save another 50gr here. That's about 1kg less than my XC bike, I'm really interested how differently it rides on the same trails.
As others have said, paint looks good but is already flaky; facings & BB threads were clean and true, small parts of acceptable quality, semi-integrated has no sleeves but was alright to build.
If I like it enough I'll buy some Chinese carbon gravel wheels and Conti TerraSpeed tanwalls. Proper ride report incoming.
