I need a new seat post bolt, any idea where I can buy these? One side has a notch on the bolt to fit into a slot on one side. Both sides are allen key

    Any half decent bike shop should sell these--or google shows a load of shops selling them. They can be different sizes,depending in whether bolt is countersunk in the clamp, so a shop may be better.

    You could replace it with one of these for £4, from your LBS. Better looking, better adjustment and just as tight.

    silver or black

    I never leave my bike unattended, so not a problem for me.

    Won't fit if it's a steel frame either as the bolt heads are generally recessed..
    Make mine an Italian, with Campagnolo on the side..

    I fitted mine on a Merlin steel frame ok. The hole is braised, instead of modern frame, where a clamp is at the top of the seat post It replaced the exact bolt the OP is showing.

    Those bolts used to be very common for steel frames. As mentioned they come in different sizes and most shops can get you one. Just take it to your LBS for comparison. There are other cheaper options besides Campag at half the price. But really, 6 quid for a probably once in a lifetime replacement is not all that bad either.

    phew the notch bit was ok, so just replaced the bolt with a standard M6? and all ok.

    But why would you need to adjust it much? I can understand if it was an MTB but not on a road bike. I'd rather not be able to easily mis-set my perfectly positioned seat post. :lol: Besides, just adds weight and maybe looks a bit clunky.......

    Probably but not certainly. I have done in 2 already and have learned to keep a spare.
    Using a torque wrench helps but I think fatigue sets in if you are close to the max.
    None of the above should be taken seriously, and certainly not personally.

    You have to be really careful that you don't over-tighten this type of bolt.

    Good link! :P If I didn't already have a spare.........

    A torque wrench may not be the complete answer but it helped me no end to stop shearing the bloody things :oops:

    Yep one on my MXL. Got to give it some TLC. Just nip it tight or min torque wrench. Lots of grease on the threads and behind bolt head's etc
