Fork crack - is the a failure waiting to happen?(7 posts)

Fork crack - is the a failure waiting to happen?NATHNOJ

It looks to me like the brazing holding the little top cap is letting go. Should I stop riding the fork? Might this be indicative of issues elsewhere?

Thanks for your opinions.

is the paint cracked also?slow-ron

Hard to tell from the picture but is there a paint crack in the same area or is it still smooth. If the paint isn't cracked I would say that it could be a brazed joint that didn't get filed down before painting. If the paint is cracked then you have joint coming apart. That could be pretty bad if it lets go on a down hill and the fork blade buckles.

That looks to be cosmetic, not structural.

1) The cap doesn't really do anything structural. Have a good check at the joins of the fork legs to the cross-piece. Anything funny there and stop riding immediately.

2) Could be indicative of other issues - old age, hence general high-milage wear and tear - impact to the forks? Do you know the history of the forks - have you had them from new?

If they haven't been in some form of high stress event (crash etc) and they are not very high milage, and you are not a 400lb sprinter, it's very unlikley that they are cracking, but you never know.

If you have some $, this would be a good time to get some new forks - take away the worry on the downhills.

I'm not so worried after looking closer. The fork has two really meaty (God bless Chris Chance) gussets on the inside of the legs where they meet the cross-piece, and all of that is perfect.

My LBS can braze and weld, so I am going to have them repair it anyway.

I have limited experience with carbon forks, but was thinking about upgrading even before I saw this. Any input on how the ride will compare?

Difficult to tell how much difference you will notice (don't know what those forks are). I have steel forks on one of my road bikes, and carbon on the other - the ride is not terribly different, but it's dependent on:

1) The particular fork in question (both construction and geometry)
2) Wheels/tyres
3) Rider weight
4) The rest of the bike they are fitted to
5) The roads you ride

In general however, they will give you a weight saving, and are though to be a little more forgiving than metal forks. I have project 2 Konas on my Jake the Snake - you know all about the road surface when you ride on those, compared to the CF ones.

I'm sure there are some fork experts out there who can give you a steer (ho ho!) on various forks - there have also been lots of threads on this issue if you have a search back.
