Tech Tip: V-Brake Arm Lengths


Gear & Tech

Despite their age, our articles on v-brakes and v-brake conversions remain very popular with GRAVELBIKE’s readers. To help folks determine whether a certain brake will clear their bikes’ fenders or fat tires, we’ve compiled a list of popular v-brakes’ arm lengths (the list will be updated as new information becomes available).

Kona Makena 20

Image
 After checking out a few 20" frames, many with geometry that just didn't make sense for trail riding, I found this Kona Makena on FB for $90. It is well loved and needs a fair amount of work. Which is exactly what I'm looking for, a good base for customisation. Pink was the requested colour from Miss 5. I quite like this pink and teal colourway. So what have we got? 2018 Kona Makena  Bald tyres Worn brakes and chain Bent derailleur  Stiff cables Smooth bearings Wonky wheels The goal is to build a bike for trail riding on greens, build some skills, and hopefully create a biking addiction.

Giant Kronos

 This is a ~1990 Giant Kronos, in great condition. I picked it up cheap on trade me. Specs: 14 speed Exage 400 groupset. 52-42 cranks, 13-26 cassette. I'm pleased it's an HG hub instead of a freewheel. 25c tyres, which is a tight fit. The plan is to just get it running smoothly and ride it. I've filled new brake shoes, tyres and cables. This is my first experience with downtube shifters. It's challenging!  My area is quite hilly so I may swap the cranks for the 52-38 Shimano 600 from my Centurion. A 12-28 cassette should fit too if I'm really struggling!
