V-Brake bosses issue

[avbro]

Hi, as a project I found and bought 00 Kona Hahanna with P2 fork. I noticed that brake bosses are welded or blazed.
That sounds not BIFL for me. Anyone here had experience of rewelding bosses' bases to have a replacable bosses?
I don't want to swap frame or fork, I have modern bike for that sh*t.

Why do they need to be replaceable? I've never broken a canti boss off a fork, and if you do P2 forks aren't that difficult to get hold of.

It's easy to replace a fork, but not easy to replace a frame. BIFL means buy it for life, I want to service it cheap and ride a lot, we have no good framebuilders here to weld in new bosses.

I have seen bosses damaged through hamfisted spannering and / or filing to 'correct brake wobble'. If neither of these applies then rest assured you'll have no reason to replace them. Personally I find bikes and parts RLML ~ rarely leave my life

I think the only time you see replaceable bosses is on aluminium frames as you need the canti boss to be steel. I'm happily riding a 1990 Marin frame as my tourer, which has now done 20+ years with Maguras without any boss problems.

I've seen a few broken bosses on 20yo Forks.
A few, out of probably 10,000.

The weak spot is where the boss mount joins the fork blade.

So a replaceable boss could still break - the advantage would be in build quality not construction style.

If one cracks, say in 2050, you could always post the fork to a suitable repair shop.

Thanks for your remarkable answers!

Steel bases with replaceable bosses are available, I've attached a picture of the ones that are available to me, although as plenty of people have mentioned, you rarely see broken bosses or bosses with heated bolts stuck in them.

Its easy enough to weld or braze a replacement on if in the very rare circumstance that a boss is damaged.
