Seriously. Haro had the trademark look of a bent top tube an everyone hated it. Suddenly you see every manufacture make a bike with a bent top tube of some sort whether it be hardtail, FS, or 29'er. Now all of a sudden they are back to the future with their old look. I find it sort of amusing because now the bike will blend in with all the others.

I do not use 12-34T cassettes either and those have been on the market for some time. There are good reasons for a smaller cassette too: * Smaller gaps between gears. Ideally, I would like to ride a 11-21 cassette, if it were not for the reduced gear range. * Shifting accuracy of the rear derailer (you do not have to adjust it to be a bit further away from the cogs). * You do not need a longer chain. If you mount a smaller front ring to correct this, this ring will wear faster than a bigger ring. If you would have a longer chain, you would have to watch out for cog-chainwheel combinations that result in too much chain slack. You know what too much slack leads to... chain slapping on the chainstays, jumping off the chainwheels, touching itself at the rear derailer cage. As for your arguments: * Crank selection? There are developments and lots of options in that area. * Reduced chain suck? A tiny bit less when you are actually riding the 36, because there is a bit more tension on the chain, but there are so much more variables that contribute to chainsuck... One of the biggest factors in the "Chainsuck triangle" (I love the article that describes it, search!) is chainwheel deformation because of pressure combined with soft material. Yes, bigger front rings would have less pressure per tooth, but that's just evading the problem and introducing a lot of others. * Wear rate? Are you kidding? How much time would you spend on your smallest gear, if you would have a triple crankset? * Drivetrain efficiëncy... I am not going to theoretically discuss small differences in percentages of a small percentage of total efficiëncy anymore. Sorry! :-D I could imagine a cassette with a 36T cog would aid those who like to ride with one chainwheel, wanting to expand their gear range. Sure, but anyone who wants a respectable gear range AND small steps between gears has no choice to use a cassette with less spread and choose chainring numbers and sizes according to the required range. Therefore, apart from a niche, it is no substitute for smaller chainrings. @Cloxxki,

And itsNOT a Sibex/spicer/chiTi - those are known for breaking. These upcoming ones stand a fair better chance. Ti fork = neato! And itsNOT a Sibex/spicer/chiTi – those are known for breaking.
