Too small for everyone I know :(

hello people, im taking a little look at this headset, in my pyjamas, on a Saturday night, on my living room floor, its been a long week.

ANYWAY, is this ordering right? I could google it but this is more fun.

Need to get this done so I can test fit a stem, mark the fork steerer and take it to a shop for a trim. Then I’m gonna build this sucker, @ltc how was the semi-integrated routing on this for you? Tips and tricks?

The cable routing was a piece of piss to be honest! There's a sort of slot for them to come out of, rather than tiny holes.

I would say that the upper bearing should be flipped

yeah you’re right soon realised that one too heh

@amey helped create a bike shaped object out of some bits n bobs, top human

but i lack organisational ability so didn’t get it finished today

necessary stuff on the way via bikepartsdotkohdotyoukay

good bike though, seems well thought out, beefy hanger screws, interesting slot-in through axle threaded widget thing, looking forward to a first ride

Hell yeah. Looks great with the silver stem and post!

There’s nothing quite like smashing it around the city on a drop bar gravel bike.
Jumping kerbs past all the Rapha commuters.
What a way to ride to work

yeah the silver is nice hey, some silver spacers are on the list too, somehow immediately lost the ones that I took off of the Kepler 😀

i am very thankful my commute goes from one bit of SE to another bit of SE and I don’t have to get anywhere near YOU or THE PROMMUTER cycleway weapons

You’ve seen my strava and I know. You are in awe.

this looks ace - silver bits really make it pop.
purple bikes are the best bikes.

Lovely looking build! Reminds me of my Arkose.

cheers ppl, it does look nice i reckon

BUT STILL NOT DONE

i only fully understood loving and hating something at the same time when i started building bikes up

Amey offered me a little guidance and the calm space to get the hydraulic stuff done which went surprisingly well.

Started in gearing. Outer cable too short. Got a new one. Time to re-route internally. This time at home without Amey’s fancy magnet kit. Girlfriend used a crochet needle to fish it out. Success. Barrel adjuster seemingly not adding tension. Got distracted when I realised that there was an old alu cable end cap properly wedged in there. Tried to squeeze it out with pliers. Crushed it. New barrel adjuster on the way.

First impressions from sitting on it is that 2cm of spacers may be too much? Could possibly even have a longer stem depending on how less stack works out. And 44ctc drop bars feel weird in how wide they are. All to be tested in practice ofc

I’m having a total nightmare and possible big idiot moment but I can’t for the life of me figure out why the barrel adjuster on this derailleur won’t work. I know I’m not the best mechanic but I also know I’m not a total idiot and do know how to install rear derailleurs and index gears so I’d like to think all the basic wrongdoings are covered.

With no cable threaded into the adjuster the screw part of the adjuster will screw in and screw out no problem. As soon as I put a cable in (with a metal end cap, with a plastic ferrule, with nothing at all) it won’t really wind in or out and won’t make an iota of difference to cable tension.

So I can’t fix the derailleur shifting up one gear in two clicks. After two clicks and the chain landing in the second smallest sprocket up the cassette, the RD will then pretty happily shift up and back down a few sprockets with corresponding individual clicks on the shifter. Then taking two clicks to shift back down into the smallest sprocket from the second smallest.

I’ve never worked on a bike with end to end outer cable and with only the derailleur adjuster to mess with. No inline adjuster or frame stop here.

I’m confused. Taking it to a shop tomorrow cos am bored of trying

derailleur shifting up one gear in two clicks

Worth checking the cable routing to the derailleur pinch bolt, it can change the leverage and lead to odd shifting if you get it wrong. Apologies if you've already done this.

No need to apologise I appreciate the suggestion!
I think it’s as it should be - what do ya reckon?

Everything I read online tells me it’s something wrong with the routing of the outer cable into the derailleur (or further up the line maybe in this case as it’s ran from shifter->derailleur)

The hole in the blanking port that you run the gear cable into the downtube of this frame is quite tight. It takes some force to slide the cable (inner and outer) in and out of this hole. Could this be impacting how the barrel adjuster can effect the cable housing?

Looks reasonable to me but I'm not an expert on this. From experience, I've thought I got the cable into the pinch bolt correctly but had in fact got it wrong. Worth checking the manual on si.shimano.com

I guess a test for the cable friction would be to re-cable using full-length outer, outside the frame, and see if that solves it. If you can be bothered, and if you have loads of spare gear outer cable... probably cheaper and easier to drop it in to your local shop as you suggest!

This isn’t one the shit shimano barrel adjusters is it? Works fine with no “load” but when there is a cable in you have to pinch it in just the right place to make it actually turn?

Maybe! f knows anymore heh

Took it to a shop and the mechanic has got the gears working after a lot of fettling but is pretty much equally perplexed as to why the barrel adjuster isn’t functioning like it should.

Which is fun!

Weird. I can’t really remember setting this derailleur up on the Kepler but i do know that i used to make all adjustments with the frame barrel adjuster not the one on the rd itself. No one else reading this had had this kinda issue with a GRX-812 before?

anyway, got to the most important bit of the build

putting stickers on 😎

Glad it’s sorted! Not the 812 but on my GRX400 I have had to use quite an elaborate, looping cable run for it to enter the mech straight. It projects out quite a bit - first thing to get damaged in a crash!

Thankfully I’m a habitual left-side crasher 😅😅

hahah love it!

real upgrades happening

this bike came with the horrible tall head screws for all the bosses. gross.

@ltc let me know if you want some of other 38 I now have spare 🤪
