My bike had a bit of a creak and while investigating the seat post screw snapped despite being torqued, might be worth a check of your bikes it looks like a cheapo one.

Funny you should mention that, I altered my seat and then snapped the bolt, I ordered some stainless ones as replacements, has been fine since.

My Focus one did the same ...light weight alloy bolt..
Swapped to ~Stainless BUT dont over torque as next thing to go will be the clamp thread, but then a suitable nut should do the job.

Yes that was what I was worried about next! Bit poor on a £3000 bike...

That is a small issue, but one that has pissed me off more than a bit! I will be checking that when I go pick the bike up from the Focus dealer and get it replaced.

Snapped it on mine too whilst torquing it. Thought that must be just a one off dud screw...
Focus need to put a high tensile steel screw there.

Steve I think you are just pissed off at the minute, hopefully they will sort it and you can enjoy the spring and summer riding.

Wrenching on my carbon bikes I quickly learned the hard way that it is good idea to use torque wrenches, so I used one on the now infamous Focus seatpost bolt. I can tell you that it snapped waaay before recommended torque. At that moment I really thought my wrench is kaput.

Snapped mine too on first attempt at tightening it.
I was using a torque wrench.
I had to chase the snapped part out of the clamp collar using a stainless bolt!

Hi Phil,
just have checked into the part list of the bike.
Seems that the bolt was changed already by us - now we use another material which seems to be stonger then the first one.

Best regards,
Wilko

Good information. Thanks for the share. It may be helpful to know that stainless steels typically do not match well with aluminum. SS is reactive with aluminum, and when SS comes into contact with an aluminum base metal, the aluminum will likely corrode. SS screws are also more susceptible to galling when used with steel nuts and vice versa. A small amount of a never seize product eliminates this concern.

Yep, mine did that as well. Did it before I'd even ridden the bike. I was a little cheesed off...

Bought a stainless steel one.
