You'll need a new headset with a smaller cup.
That one is unusually large, I think.

It's kind've a pain to remove and install that particular bearing surface, especially without the appropriate tools. If you have a really kickass bike shop in the area, now is the time to make their acquaintance.

Fuck.

I just installed this thing. I do it ghetto style because poorfag. It has sealed bearings, perhaps that's why it's so large. Aw... shit. You sure I can't spacer this somehow? Getting the headset out is no problem. Installing crown race/headset is hell though.

I have no idea about anything related to ghetto-rigging a headset. Never heard of such a thing. Sorry.

No, I meant is it possible to put a spacer between the calliper and the fork, so I can install the brake without re-installing a new headset? Or would that bring the brake out of alignment with the rim?

See that washer behind the caliper?

Put two more on there. Narrower ones that clear the crown race. and then say FUCK IT MAN I DON'T CARE

If it's a sealed bearing, I suppose you could just file down the edge where it contacts the brake.

Depends on the calipers.
Some have a lot of adjustability, others have very little.

Consider this and decide if there really is any risk

I'm no internet bicycle engineer but I know calipers come in significantly different lengths and those mm don't matter. Like converting from 700c to 650b on a roadie.

And I know I've seen both V and caliper brakes mounted on the REAR of the fork, totally different angle than standard caliper position

I think it's fine. I wouldn't have even remembered doing it if I was building up a bike

If you are worried though, ask on the bike mechanics forum on bikeforums. They'll nerd out hard on this one

That's what came to my mind. But is this okay to do safety-wise? I mean will that not hinder the brake from working? I assume with re-adjusting the brake pads, nothing could go wrong, huh?

>>967594
Uuuh... that is an idea, but I'd rather keep that as a last resort.

>>967600
pic related are the exact brakes I'm using. I try to think positive and will see if it'll work with spacers

>>967602
>>967603
Thanks bros. Will look into it.

I worked all day on this thing and was looking forward to attach the brakes as a last step for today, to imagine what it'll look like when it's all done, and then this shit happened. Ah, but when does it ever go smooth, right?

When you build with components made within a decade of each other?

my experience is it never goes smooth unless you are building a totally vanilla, time-period correct spec with nothing at all changed

And if I was going to do that why do they keep making all these cool weird bike parts to fuck with

Also, estimate your budget and then double it. lol

this so fucking much. you need a special tool for so many little shits, in the end you would be better off bringing it to a bike shop for assembly.

while this is true, and the cost of tools is intimidating, you should also face the fact that if you're planning on doing any significant amount of riding for any significant length of time, you're going to end up raping your wallet in the long run paying for bike shop labor

MGTOW DIY cultists habitually understate the cost of tools and the cost of mistakes resulting in damaged parts, but the flip side of that is that in the long run, it IS better to do your own work and just suck up the cost of the tools

Mechanical engineer here.

All the fags telling you to replace the headset or fucking file down the edges of the bearing cup and the fucking bearing itself are nutso.

>>967593 has the right idea. Just stick a couple small washers in there to space the caliper further forward. The few extra mm spaced forward aren't going to matter, and pads are adjustable for a reason.

>>967608
Yeah but that's no fun.

The few millimeters that you bump out the brake caliper won't impact anything. Use the washers. Also, post pictures. That looks like a sexy fork crown.

Mechanical engineers are the people you hire to stand around and point at the problem and scratching their heads or to panic at every instant

Then you hire someone who knows the industry with experience to actually solve the problems

Just file down the top of the caliper, it goes under the headset anyway so it wont matter how it looks. Just use a fine grade.

There is nothing to see yet really. It's still a work in progress. Will definitely post in PYBT when it's done though.

By the way, I decided to install a different headset from my previous bike. The one in the pic was really cheap and I can still keep it as a spare. I guess I'm too much a diva, because I just know I'd always look down to those washers and get triggered.
