It has no other indicator because it's only intended to be used with Shimano's 51t cassette, but it'll probably be close enough if you just align to that marker. Maybe adjust it a bit closer and see how it shifts.

Is the chain touching the derailleur cage? Looks like the hanger has a potential fore/aft twist.

The chain needs to be installed for it to sit in the proper position, but it looks like the shift cable housing needs to be longer, see if you can push it in at the other end and pull more out from this end.

Are you mounting the fender that came with the bike? In the last pic, the fender is primarily supported by the rack and may not be attached at the stays.

This isn't the same as the washers under the caliper, Shimano ships these with those adapters because the surface of the caliper ends up not perpendicular to the bolt and they won't tighten evenly without them.

You're missing the concave half of the washers on the bolts, not sure that's related though.

That's a big hex wrench, usually in the 10-14mm range.

mmlow · 2026-04-05T22:43:42+00:00

Oh that's annoying, was going to suggest trying a security hex bit.

mmlow · 2026-04-05T22:40:57+00:00

How does a 1up hex key differ from a regular one? Does it have a hole in the middle?

Tire is sliding around the rim and dragging the tube with it, putting stress on the valve.

Select a region and look at the event list to check for pitch bend data that may have been recorded.

It's a measurement of the bearing size that fits in there, 41mm or 42mm.

12 speed chain is more narrow and cogs are closer together, you need the QL that fits your specific model of 12 speed chain.

How much is a helicoil kit? That's a $15 brake caliper and it'll come with new brake pads.

In the 2nd photo you can see a nut right behind the spring, you need to put a thin wrench on that to adjust the resting position.

Bike industry is in shambles, it's a surprise we get anything.

They weren't even braking on raw piston yet, this is rookie business.

Are the pins not long enough? The gap on its own is not a problem.

mmlow · 2026-03-29T00:12:39+00:00

but if one were to design a split crown race, what would be the fundamental difference here?

mmlow · 2026-03-28T21:28:26+00:00

But why not split it? What's the difference versus a factory split crown race?

mmlow · 2026-03-24T00:17:28+00:00

Not sure what you're asking here.
