This SRAM video on replacingthe hydraulic hose involves removing all the fluid from the system - the situation you are in now. At the end it says to bleed the brake then links to the standard SRAM bleed process, so presumably that's what you need to do. The standard bleed process is designed to displace all the old fluid with fresh, so the lower syringe must ...

The numbers don't tally because you're measuring wrongly, I've marked up your photo with the circle (in yellow) you should be measuring, it's more like 147mm, or whatever irl without camera perspective distortion. That's much closer to the calculated value - 88 mm adjacent = 149mm calculated BCD. Measuring guide: Terminology index - a list of bike part names ...

It looks like you have a crankset with non-removable chainrings. The 'bolts' you are measuring the geometry of are just screws holding the chainguard on. The chainrings appear to be pressed steel and attached at the crank axle. It's much more likely the pressed steel rings are bent than the bottom bracket axle, so replacing the entire crank is possibly all ...

Before buying a replacement ring I would recommend removing the crank assembly. This requires a "square taper crank tool"along with a socket and ratchet most likely 14mm. Once off the bike edit your question to include photos of both sides of the assemble. Try to determine if the crank is bent by laying the crank on a flat surface (pedal side up) ...

In such cases, I often check ebay or similar marketplaces for a used/best offer/parts only item to scavenge the needed part from. One often needs to be patient and make multiple offers before succeeding. As far as compatible replacement parts, si.shimano.com documents may indicate compatible parts if you haven't checked there yet; alternatively, a local bike ...

My first thought is that the new shifter isn't compatible with the chainring spacing, but unless this group has a super-narrow profile I can't think of one that would be as wide as a typical first-to-third chainring spacing. In my experience, the markings on twist-type shifters are not always equidistant, and may be due to non-linear throw of the derailleur ...

According to the installation instructions the manufacturer calls this a "dust cover cap." As you note, this is not a headset or stem cap since it doesn't mechanically engage with the stem to preload the bearings. A Google image search for the image you included found a bunch of pages on Amazon describing this as a "Delta Cycle stem raiser,&...
