The seatpost itself won't, but some titanium frames have aluminium inserts in the seat tube. The presence of a titanium seatpost against the aluminium in an area that may get quite wet can result in the aluminium corroding.

Re: ...why so many bikes are such boring drab colours these days?

It's disappointing that technology has improved so much that customizing products for each user should be easier and cheaper than ever, and yet the improvements are instead put into mass production of a minimum of variants, and the general public seem quite happy with it like that. Personally I've h...

Re: What is a Gravel Bike?

74 and 73.5 degree seat angles are pretty much the norm for gravel bikes. If it's the case that 'you can find whatever you want', please give me some examples (plural) of gravel bikes in a 'medium' size with a 72 degree seat angle. I'm not going to go trawling through the internet to find them for ...

Re: What is a Gravel Bike?

More capable off-road than a touring bike, less designed for full load bearing So that would be less capable off-road than a touring bike then. Shorter chainstays, steeper seat angles and shorter wheelbases will contribute to a livelier, more responsive ride. Except that the further you ride, espec...

Re: What is a Gravel Bike?

They can also be compared to touring bikes, as they are built stronger, and more likely to be designed to take mudguards and racks than standard road bikes, but they usually have shorter chainstays as they aren't designed to carry as much.

If KM2 was really referring to 3D printing, then it's probably selective laser melting, which can be done with any of the metals used for bicycle parts.

Re: Wooden Mudguards .... Aye or Nay?

I note that the Squaretree Woodguards have their stays outside, in the continental way. Seems a good idea. Is it? I don't think I can say that it's better or worse. In combination with the thickness of the wooden mudguards, it let me countersink the fixings, so the inside surface of the mudguards a...

Re: Wooden Mudguards .... Aye or Nay?

I can offer an opinion, as I have been using a pair of wooden mudguards for over 5 years now. They are Squaretree Woodguards*, which are flat, and consist of both wood and a thin layer of aluminium glued underneath. The attached photo is from when they were new; they are faded compared to that now, ...

Repurposing old bike parts

If you do a lot of cycling, you're bound to end up with a lot of parts that aren't suitable for reuse, but it seems wasteful to throw them away. Inner tubes are a common one. I have used a few of those for suspending hard drives, to damp their vibrations and quiet them, like this: https://mrevil.asv...

Re: CAAD 12 Durability for commuting.

10 Brucey -- what you say about carbon frame aluminum inserts dissolving is scary so has put me off carbon frames. That's mainly a problem with early or poorly made carbon frames where aluminium parts are bonded directly to the carbon. Better frames will electrically insulate the aluminium, so ther...

Re: Wheels - number of spokes

...So to put fashion considerations ahead of wheel strength in a touring machine is (IMHO) a pretty dumb idea. Adding four more spokes per wheel 'costs' about 30g per wheel... You can make exactly the same argument about any chosen spoke count; going up to 40 spokes is only a small penalty, and 48 ...

M5 bolts are stronger than you might think. Strong enough to carry the weight of anything you might reasonably put on the back of a bike.

Re: No fuse in battery charger for 8.4v bike light battery?

I do want a decent version of this but it's a weird voltage and seems specific to bike light battery packs. It's easy to find adapters with several fittings that plug into just about anything with 3V/6V/9V settings but no 8.4v setting. Trust me if there was a £9.99 plug that had Japanese internals ...
