My bike has some sort of no-name linear pull brakes. The front has a 'power modulator' (spring in the noodle for antilock).
With the Bafang levers that came with my BBS02 kit (two-tone, silver with black grips), I can't get an adjustment that feels right. Even adjusted so the pad is about 1mm from the rim, I can still pull the front lever all the way to the bar with one finger. The rear feels better than the front but still not good.
I found this old thread with a similar problem, which got me looking at the Travel Agents which led me to this article by Park Tool.
The article says the pivot radius (see figure 2) on a road brake is 21mm and on a linear pull it's 42mm. The radius on the Bafang levers is about 28mm and the radius on my bike OEM levers is 35mm. This is really confusing because basically each type is 7mm away from the next:
'Standard' road / cantilever lever = 21mm
Bafang lever = 28mm
My OEM linear lever = 35mm
'Standard' linear = 42mm
So I can't figure out the best solution. Using the Travel Agent with the Bafang levers would be like an effective 53mm radius which is a lot more than a 'standard' linear lever radius, and WAY more than my bike's OEM lever's radius.
Is there a type of caliper I can buy that will work well with the Bafang levers with or without a Travel Agent? I don't really want to use the Bafang adapters meant for hydraulic brakes where you have to glue them onto the levers somehow since I don't like how they look.
