No. This would remove too much material... and the cups that are missing too, making it even weaker.

pro: narrower than magura hs33

I was riding dual disc brake in a town park lately, rocks on a small hill. Many people there looking for rest and relaxation. It's simply impossible/rude to ride grinded front HS33 in such places.

echo crown bottom side with ~zero camfer will damage all 1-piece steerer tubes I can think of

why off topic? ECHO crown race arn't compatible with most one piece steerer tubes that have a 1...2mm radius. They can't be fully seated and will push in a sharp notch.

echo crown race?

looks like it cracked below the headset crown while usually I would expect the steerer to crack above. That Tensile Ace headset comes with non-split crown. Any defects on the steerer tube from removing the crown using a screwdriver or similar in order to glassblast the fork?

you check your bike for cracks regularly and replace before it falls off...

how can a mechanical disc brake have pistons anyway? That caliper should have twice as much cable pull per given pad movement compared to an avid BB5/7 where only one pad is moving.

I had a mini master unit upside down on my bike for a bout 2 years. No problem if there is no air captured inside the reservoir. There will be no air inside if you roll the diaphragm. To make 100% sure can fill the two m3 threads with fluid before installing reservoir cap. How to - Roll a diaphragm:

tensile uses 1 o-ring and 1 dirt wiper, racing line uses two o-rings. The outer o-ring will pull dirt/abrasive to the inside because it is not formed like a dirt wiper.

must be the first trick in this video where it happened:

most freewheels have a 36x toothing with groups of 3 pawls and offset between them 1x3 pawls=36 2x3 pawls=72 3x3 pawls=108 4x3 pawls=144 The welding points may be a way to use less tight bearing fit and thus avoid high bearing friction.

18-13 with 175mm cranks on my onza zoot. Much better than 18-14 considering it's a street trials bike. 18-12 would be too much for pedal kicking...
