Hi
I love my Sterling.
However I've noticed that the 2 bolts that lock the handlebars to the forks (visible when looking at bike from the front) are rusty.
Is there a reason why these bolts are not made from a non-rusting metal (e.g. stainless steel) ?
thanks

Stainless steel is one of the softer more ductile steels.
My stem bolts are not stainless either.

Thanks
So one should expect them to rust ?
Is there a suitable alternative metal they could be made from that wouldn't ?
Sorry for being a bit dim but I was just surprised by this, especially if there is an alternative.

The bolts on the front of the handlebar stem on my Raven Tour rusted quite quickly, but they still seem to be working, three years on. It does slightly spoil the look of the thing but, on the upside, I muse that an expensive rusty bike may be less likely to be pinched than a shiny equivalent!

The stem bolts have rusted on every bike i have ever owned, so it's not just a Thorn thing. Did manage to buy some nice coloured anodised ones for my mountain bike though. The chrome/anodized plating seems to come off though when you insert a hex key. Never had any fail because of it though.

M7 are as nearly as rare as hen's teeth, I know because I have a Nitto seatpost which uses them and I had to source a longer bolt for the saddle clamp.
I suspect the stem bolts will be M4 or M5.

you could possibly look at getting the m7 screws in titanium.

Thanks everyone
Kind of reassuring - but still puzzled why a bike (especially one that is built so well & prides itself on sturdiness) would not have rustproof stem bolts fitted ie. titanium
