V-brakes Shank Component
Hi. I have a Canondale Hybrid and want to install new V-brakes however the existing v-brakes have a shank of about 1cm that moves the v-brakes away from the fork. On Shimano v-brakes there is no shank and the v-brakes is more or less flush onto the fork.
So if I install Shimanos then there is a 1cm gap between the v-brake and the fork, with just the spindle showing, where rain can get in.
What can I do about this? Is this a common problem? Are there standard shank extensions or washers?
Photos attached of my bike forks.
Actually I can't attach photos yet not enough posts it's at h t t p s .... ibb.co/7jD59WP
Cheers

Agree with Wilfred about terminology, photos are universal langrage.
But I'll say something about water getting inside of things. It happened pretty nearly no mater how much shrouding simple sleeve/bushings have. I seriously doubt that the OEM brake pivots are any less or more subject to water penetration then the new ones will be. Andy

The gaps between between the frame brake bosses and the bushings of the v-brakes are pretty normal, but yes water and dirt gets in there and eventually hinders the pivot. You've got to take them off, clean and regrease them once a year or so. If you really load them with thick grease that might help seal them better but it gets messy.

The amount of rust suggest this bike has seen a lot of what I call "exposure". This suggests that not enough maintenance is done to keep up with conditions. Andy

Here's the same image. I lightened the Gamma on it by 190 using Irfan View.

How about a picture of the Shimano v-brakes that you want to install or a web site link to them.
The nib of spring that is on the back side of the pivot arms must engage a tab on the inside of the boss.
Take a look at this video to give you a better idea how these brakes install

Andy, I like your definition of the "exposure" for this bike!!
I am going to use that at the shop when people bring in neglected bikes!

Part of the skill in a service guy is to be able to speak the truth without having the customer loose face. Sometimes I do a better job at it then many, sometimes less so. Andy

One thing I couldn't help but laugh at was 'sad bars' - usually Huffys and Murrays and other very poor bikes with ultra cheap steel handlebars, the ends of the bars would gradually bend downward so the bike had a frowny face when viewed from the front. As a customer walked toward the shop in the back of the store I would say 'You've got a sad bike.' and then try to show them what I was talking about. I don't recall anyone being offended by this, but a few seemed willfully blind to it, as if to deny that buying a $79 bike might have some drawbacks.
