Ti spring go snapp!!!!!!!!!!!!

[Biffff]

My bike lets out a crack after a landing today. I stop and check it out, and find my Ti spring to be cracked in two. It is 2 years old but I'm thinking that shouldn't of happenned.
Anybody else experiance the same thing????? Do Ti springs have an expirery date?

It was a manitou Ti-spring and a CCDB. I think I'm just going to order a Ti spring from Cane Creek themselves this time, as the Manitou spring was fitted to my old DHX for most of its 2 years of use. I put it on the CCDB as I didn't feel like dumping the extra $200 for the CC tI-spring at the time. Hopefully the CC Ti springs are better quality.

did you run a lot of preload on the spring?

i cant wait for everyone to blame manitou for it cracking.....wait for it.....waaait.....

What frame?

Measure the length from collar to collar exactly the way it is now, and then look up the exact free length of the spring. Get back to us with those two numbers and the stroke of the shock AND the spring too.

no. One turn maybe. It is a 500x2.75 spring on a 8.75x2.75 shock. Like I said it's been used hard for over two seasons so I'm not blaiming Manitou. I actaully think Renton or another company made the springs for them.

I dont think RCS made those (the super light ones) but it would depend on when it was made etc. If it is one of the older (super light) Manitou ti springs with few, widely spaced coils it would make sense that it would not last forever. In general, the fewer and wider spaced the coils, the higher the stress at a given compression. The 'one size fits all' RCS springs that are currently available have quite a few coils at lower pitch, resulting in a lower stressed (yet heavier) spring.

I'd say its not the super light widely spaced version. Heres a pic

It can happen. I had a steel spring snap on me once. A standard Fox spring. It was the right stroke, right weight, no excessive preload or poor setup- just developed some kind of crack at some point (only know this because I saw a bit of rust on the inside of the spring where it broke) and then gave out. I don't think the spring was defective or of inferior quality...it just broke....

[pyynö]

yep, same here. Normal Fox steelspring gave up after two seasons of regular abuse... Same pattern as above little Crack in the spring and, my guess, Snap and Pop wont be left far behind

Pix of snap!

[Gary]

every single Ti product I ever bought (back when I cared about light bikes) snapped.
I've also snapped a Fox steel spring so wouldn't even think about spending loads on a Ti spring to save 150g.

[nowlan]

Ive heard of them snapping before. Sucks Daver, at least you got 2 years out of it.

[dhkid]

did you spring rub on the shock body? as far as i know manitou springs are standard size, and the ccdb requires a 1.5 Id spring.

the reason i ask is because ti is very sensitive to scratches, that's why ti parts are always shot peened to increase the surface hardness.

The same thing happened to a spring on a KTM 300 that a guy at my work races. I will post pics later.
