Stuck saddle bolt?

[darrensmith0410]

Trying to change my saddle is proving difficult. I'm a complete novice when it comes to bike mechanics, however it seems to be a 'single bolt clamp'. The bolt is steadfast, I've tried an allen key, tapping it with a hammer to loosen it but nothing is working. Searching the internet only brings up stuck seat posts!

Would be grateful for any tips.

Drill it out, the bolt should be made of cheese

Try soaking the bolt with plusgas

Cut a groove into the head of the bolt, and use a socket set to get some more leverage. Or use an ‘easy out’ or similar

Is it the bolt under the saddle that's upside down ? ie there's no nut involved

Remove the seatpost and saddle, soak the bolt in WD or plusgas or similar and let it soak. Have a cuppa, relax. Try again.
How good are your allen keys, are they cheap short ones ? You can't get much leverage with them, in which case you can use a ring spanner over the end to increase leverage...like this..

If you have a length of pipe, take the saddle out and clamp it somewhere, then hook the pipe over the allen key and use the extra leverage.

Have you tried using a Allen Key socket set?

Yes I’m using crappy little Allen keys, will give this a try. Thanks.

Have you drank blood of the sacrificial lamb? Sometimes my bolts won't come loose until I've honored Odin.

Blood sacrifice is important in these cases, but it's usually just enough to give some of your own from, for example, a scraped knuckle. This is where the crappy little Allen keys come into play, as they'll let go at just the right moment.

Smack in a Torx from a socket set and try that.

Surely that's for when the OP has rounded the hex socket off. I didn't think things had got that far yet.

Are you 100% sure you are turning it the right way?

Which way is the right way? I think you should at least add that value to your post.

Lefty loosey, righty tighty
