Culture rather than fashion, please.

Ah, SCR. The worst thing about shaven legs is that when you scalp someone riding a hybrid or road bike when you are on Brompton or Boris Bike, they may take solace from the fact that you are probably a fairly serious rider, and thus they are not completely broken mentally.Womack wrote:Hairy like a fox!Seez wrote:Not using clipless?

Well, not quite - I'm not a ghinge like.
I do so enjoy scalping shaved roadies with my BMX pedals, hairy legs, baggies and less-than-stellar physique. Of course, from time to time I'll pass one who's actually half-decent and will be summarily put in my place, but that's all part of The Game...

My understanding is that it is very expensive and time-consuming to machine/weld. Aluminium offers a slightly inferior strength to weight ratio (for frames) but greater stiffness and lower cost. At the higher end of the market CF offers better strength and stiffness but lighter weight.DOB wrote:Replicators I think?Seez wrote:How cool is this:

I was starting to wonder what had happened to titanium bikes. Pretty much all the bikes I'm seeing now are either Carbon (expensive level) or Aluminium (mid-lower range), with the occasional frame still built out of steel. Am I missing something, or is Ti not now as common as you would've thought it would be by now?
You just know that within 50 years they'll be giving away free 3D printers with every iPad, but the ink cartridges will cost more than a new car.Apposite wrote:There are quite a few manufacturers making Ti frames and as you say lots making parts.
That printing style of manufacturing is going to be amazing for the likes of aerospace, automotive, bikes etc. where we want to construct complex, high performance, lightweight parts out of expensive materials. Still, there are significant issues of speed and scale to be addressed before items made like this will have low sticker prices.
I have a titanium hard tail. Essentially Titanium is very expensive, heavier than Al and tricky to weld and machine. It is lighter than Steel and has better dampening properties than Aluminium but with decent relatively cheap prodominantly Al full suspension bikes and improved composite production it has been priced out. composites are lighter can be produced to have decent dampening properties and not much more expensive. Al is lighter and cheaper with full suspension not being so heavy and expensive anymore essentially Titanium has kind of lost its niche. That is why I think Ti bikes haven't become more common in moutain biking.DOB wrote:I googled it, and it seems there are some dedicated Ti builders out there, but it doesn't seem to be a common thing. In fact, any google reference to Ti and bikes seems to bring up the EADS/Charge link above.
I do seem to recall seeing various Ti parts available, bars, seatposts etc, which would lend to the idea that since it's difficult to machine, it's fine for straightforward parts, but not so fine for more detailed components. Hence why 3D printing could be the factor that kicks it back into vogue (though, of course, CF and Al could both benefit from the same advances in the same way).
We're sitting here speculating about market forces, manufacturing processes and intricacies of bicycle design and handling, when it could be as simple as "well we were offered a job lot of Xkgs of Y-grade Al for US$Z per, and couldn't turn it down."Petej wrote:Note: this could be complete rubbish.

Wommers, I am surprised to see that you are actually in accordance with Rule 33 on this.

If you compare that to the consequences of not being able to get a foot out and back to stop yourself crashing into rocks, trees, and other solid objects, then its easy to see why people go for flats.Gospel wrote:I can't remember the last time I saw anyone other than a fat old granny or kids riding without SPDs and I get every kind of rider passing the door as I'm situated on one of the most popular cycling routes this side of Londinium. It really is quite interesting to read the differences in thinking. Whatever works for you I guess but it's just plain daft in my view because you're giving up on so many advantages.For a weekend warrior its often far more confidence inspiring to be able to move your foot off or back onto a flat pedal. A lot of MTB coaches have a preference for teaching people on flats to give them proper technique.
One of the most important parts of material selection is how expensive is it (particularly for short sighted company bean counters who don't see beyond the end of the financial year). For example power company A and power company B can buy a load of T91 steel from the previous company they bought it from (for slightly more) or from a new company in far east (for slightly less) both choose to buy from the cheaper producer. Power company A then fit said T91 to their power station alas half a year later it has a catastrophic failure of a pressure part while power company B hasn't fitted it but has it tested and finds it is shite. Money saved = none at all. increased power station down time = money lost.

That's more or less exactly what I rock on my MTB, not sure what 5.10s I've got but they are ridiculously grippy - almost too grippy, if you don't place your foot properly when setting off it can be a bit of a nuisance to shift position to something more comfortable. Not a problem to get the foot off the pedal if need be mind.fisgard792 wrote:

other advantage of spuds over a juicy set of grub screwed flats is that the pedal kiss is less painful
That's a figure oft' quoted for professionals who spin their legs properly. Most amateurs will derive huge benefits from using something like SPDs because they make you pedal more evenly. I suspect the nay-sayers are just afraid of getting their feet stuck and falling off. I'd be amazed if anyone who's tried them for an extended period has ever gone back to flat pedals.The only advantage you're giving up on is maybe 10% pedalling efficiency
I don't mind admitting that's true in my case, but that's only partly it. As I keep saying, I just don't feel the need to be clipped in, and the lack of clipping in does not inhibit my enjoyment of the cycling that I do in any way, shape or form. And I may come across as delusional in this regard, but I also don't think I need to be clipped in in order to be able to pedal a bike effectively, or at least effectively enough for what I want to do with it. And in general, I take the view that if there is a weakness in my technique, I should improve myself to overcome it rather than beat it with technology. This is undoubtedly the misguided perspective of the luddite and inveterate tosser, but there we go.Gospel wrote:I suspect the nay-sayers are just afraid of getting their feet stuck and falling off.
Having only recently started using spds they really make a huge difference particularly on uphill sections as you smooth out your pedalling so your back tire doesn't slip so much. Admittedly I have fallen over a several times due to them (the last time I had enough time to pick a soft spot to land). Don't pull up at the traffic lights next to police car and fall into it like one of my mates did.Womack wrote:I don't mind admitting that's true in my case, but that's only partly it.

Hey I use SPDs and usually stack it on very steep, very tight uphill corners .. there's no accounting for bicycling talent or in my case the distinct lack of.Womack wrote:Yeah, I do struggle with really steep, sharp uphills on the MTB, but I refuse to accept SPDs are absolutely necessary to surmount them. Occasionally grinding to a halt, taking a pedal to the calf and having to push the rest of the way up is nature's way of telling me to MTFU and sort my shit out. Or something like that.

I've ridden for years without them and whilst I like using them now, they do not give that much extra power on runs.
A lot of top downhillers still ride flat pedals regularly, Sam Hill dominated the World Cup scene on them, Brook MacDonald recently won a World Cup stage on them. To race, most of the top downhillers wear SPDs because they give them a very slight speed advantageGospel wrote:They provide stability and stop your feet bouncing off the pedals which can be a f**king disaster.

You are talking to an ex courier and BMX jumper.Bindi wrote:The benefit of being attached to your pedals is immense. Anyone who says otherwise needs to man the fudge up and learn to use them properly. You simply cannot accelerate nearly as fast without them. Add in less rotational weight + a stiff set of carbon-soled shoes and you waste no energy whatsoever. I use them for everything - from downhill racing to road. Dirt jumping is the only thing I would avoid (not that I do it anyway).
You can get some good bargains on line but you want to make sure it fits you. Best bet is to go to a a good local bike shop and try some out, or even pay for a proper fitting somewhere.

Depending on the cycling purpose, it is an individual choice as to whether to go clipped (strapped) or clipless (non-strapped).
If you're a commuter for example, it might make sense to have the clipped option.
If you cycle (race cycling, touring cycling,) it makes sense to go the clipless.
It is much more efficient for pedalling.
I think Sean Kelly was the professional cyclist to convert to the clipless regime.
This. And do your research / talk to a trusted local bike shop person. I did quite a lot of shopping around before settling on my hybrid, and for the price I was willing to pay got a great deal on a lesser-known brand (Brodie - well respected smaller company from British Columbia) as they tend to put a better set of components on than other company's bikes in the same price range.Seez wrote:You can get some good bargains on line but you want to make sure it fits you.

It's a good time to buy now as next year's stock is coming out soon. As for brands to avoid, if your budget is over £500 you don't really need to worry. They are all made in the same factories anyway, except for a few top end frames.
