Mockba 80 Fixie - Mock Build
Finally! Got the headset installed at a LBS. Could not wait to get everything up and running.
Assembly was pretty fast, the only tricky part was getting the chain to the correct length and adjusting tension of the chain on the cog and chainring. Well, chainline seems ok (about 45-46mm) with the outer position of the crank spider BUT, though it looks straight (almost), the drivetrain is noisy! I tried tensioning even more and slacken a bit too, but to no avail. So, I moved the chainring to the inner position which gave a chainline of about 40-41mm, still no improvement, drivetrain is still noisy! The inner position is a no-no as the chainring is dangerously close to the chainstay.....<1mm clearance.
So now the big question is : Is the chainline causing the noise OR simply the chain itself? It appears that the sound is coming from the rear cog area, not the chainring.....
So the quest continues......in the meantime some pics.....
Handlebar is super-low and its pista (did not know when I got it!!!)
With the brakes mounted, about 8+kg estimated, guess it will be in the 9kg range with the pedals mounted!
Simple and looks minimalistic without the brakes!
The Rolls seat is quite old and obtained via eBay, a bad transaction as the quality is not good at all! Oh well, you win some, you lose some..
Chain line with with chainring @ inner position...I need to swap this back to the outer. Looks like I gotta spend money on that BB AGAIN this time it will be a DA 7410, NOS....out of production, just like the headset I'm using.
