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

You only need three more posts to get to the magic '10' where you can post pictures. Reply to this and you only need two!

...because I have no idea what you are talking about without a picture.

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

Thanks for posting the photo

I will try to get one in the daytime that is clearer.

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

Many years ago I trained myself to refer to POS BSOs as 'less expensive bikes' so not to insult customers.

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.
