Hi all, 

I’m curious what people here think about titanium as a material for bike parts. Is it really the best option, or is stainless steel good enough for most people? I’ve seen quite a few people say stainless does the job just fine, so I’m wondering when titanium actually makes sense. 

I’m also interested in how much weight saving matters to different riders, and what people usually change first when they want to lighten a bike. 

I work with bicycle components, but I’m not promoting anything here — just interested in hearing what riders think.

Cheers

Alloy seat posts are usually anodised, and that should help stop corrosion just as well as paint.   But it obviously does not!

Often MTB style bars can be cut shorter and I personally find that gives me a better, narrower, position for road use.   One thing to watch out for, a lot of modern MTB bars are for ‘oversized’ clamps.

As PH has said, there are lots of different shapes of handlebar.   The MTB ones I use are 1990s style, almost straight.  The straight bar position can be made to be very similar to using the top of drop bars and if short bar ends are used they can give a position very similar to being on the hoods.  On one bike I use Ergon GP2 grips which have a built in bar end, on another cheapo ebay ergonomic grips and shortened alloy MTB bar ends.

Ergon grips can be bought with a shorter RH grip to accommodate the rohloff shifter, but I guess on a Sherpa you have derailleurs?

I fought a 3 week long battle with a secondhand Fuji Track frame and seatpost a few years ago, I tried WD40, Plus-Gas, gearbox fluid and acetone mix, clamping the seatpost in a bench vice and turning the frame, then tried dissolving the seatpost with caustic soda (aluminium post in a steel frame) with no joy. Eventually I bolted 2 hacksaw blades together, cut the top of the post off and after several slow and careful sessions managed to cut the post into 4 strips from the inside, grip them with mole-grips and twist/pull them out. I now have the remains mounted on a plaque in my garage to remind me that greasing seatposts is part of regular maintenance.

You mention trying to get more leverage but not what leverage tricks you've tried yet. If you have an old scrap saddle try putting this on the post, you can then hit it, twist it, put it in a vice etc without worrying about damaging your good saddle.

Personally if I couldn't shift a seatpost after a few days soaking and some leverage, and the frame was a nice one that I didn't want to risk damaging, then I would now send the frame off to a specialist. There are companies out there with a pulling machine that will safely remove it for £80.

As B Cereus noted, a hair dryer can be a good source of heat.

I would certainly trust using it for several minutes at a time, but not for extended time.

A hair dryer is designed to be used for a few minutes at a time.  Leaving a hair dryer on for much longer could damage the hair dryer.  I set a hair dryer on something to provide a continuous steady source of low level heat at a low setting, after about 10 or 15 minutes the hair dryer quit running, and never ran again.

I used a hair dryer to warm up my frame bottom bracket shell before I used significant force to remove a stuck bottom bracket that I wanted to remove from the frame.  I can't say if the heat helped or not, but it certainly did not hurt.
