Staff Rides – Aston's European-Made Nicolai GeoMetron Super Bike
However, bike looks totally retarded (dont mind ride quality of course). And one thing i dont like the most is that drive-side chainstay, way too close to front sprocket, probably even worse with full compression. Its sick ride tho, somehow 'exotic' :)

Shimano Patent Filing Raises Electric Questions
@captaingillooley: We used to say the same about old mobile phones, do you remember that they last at least 5 days without charging?!

Staff Rides – Aston's European-Made Nicolai GeoMetron Super Bike
Only fore and aft, but they feel like a peanut butter in corners, where some torsional rigidity would be very much appreciated. Jokin, just can not believe that single crown, usd forks with no connection between legs above the upper part of tyre and below crown can be considered as 'stiff', without some square-shaped connection between lowers and uppers. At least even leftys have some single-sided, dual crown. Lowers are exposed to rotation, and they are only connected at the axle. Never rode one besides old Shivers, that were kinda i-want-them kind of flexy shit

@vitality: Polish brand Candy Ray makes some top-tier, high quality and pricey cockpit bits. Just a touch of having a fully customised bike with carbon bars that are low quantity, rare item. Sure polish brand Dartmoor make their alloy parts and frames in Taichung, Taiwan, but they're designed, tested, and engineered in Poland.

Just to say... Fork fore/aft stiffness should be crucial for given head angle. Fork/frame connection also. This bike parts are mainly Germany/UK/ a bit of Italy and a sourcing from Poland, some bits from Romania and Switzerland, aren't there really other GOOD quality- and price-wise brands in the old land of Europe? If someone's interested, polish brands Antidote (top quality carbon frames), which is oh-so-pricey, and cheaper, but very popular and good performing brands- NS, Dartmoor (at least i know that most of Dart alloy parts are made in Taichung, Taiwan; not sure 'bout NS) are really good contenders, so if You search for something european, check them out. Cheers, build is impressive, even with this weird forks haha! Hope they designed and engineered it for some proper riding! Always in search of some other options (ofc big players have it pretty dialled, but just look at a new Formula downhill fork with a solid gazillion ways to adjust its performance, Storia shock, OR fcken Dugast tyres made to order, which were ridden to some insanely good results under Nino Schurter a while ago) If you're lookin for some really hipster-every-part-numbered-and-signed brands, check out awesome Garbaruk components (Ukraine)- heard of some very light and top-tier chainrings, and Polish brand Candy Ray, which makes some really well engineered carbon parts (both brands are pricey, thou, but this kind of making your own rig so custom, and contact with those guys is on another level. If you look for something REALLY standout (or weird, or just wtf?!), check out polish Dark Owl brand, they have a steel high pivot made to order (and probably ones preferences) four-bar downhill frame that just looks to get punished and go away unscathed (Antidote's Darkmatter is another example of polish high pivot, four bar linkage frame- with an asymetrical linkage, that drives the shock, just... outstanding) and speaking of Europe there's a brand called Sick! bicycles, these guys take 'low,long and slack' treatment to another level... And of course, so-freakin-innovative finnish Pole, with their CNCed alloy 'machine', that's one of its kind. Don't forget Bold with their linkin frames with hidden shock, Deviate that makes awesome high-pivot, gearbox driven and well equipped bikes, Production Privee needs no introduces, Starling Cycles and their full-cromo Murmur, that put sme big brands' bikes to shame with it's awesome material-driven riding properties and proper geo, and a lot of manufacturers, that can make the frame to your own needs, with parts chosen by the end user (I still think of polish brand Zumbi, but don't know if they still weld their awesome alloy creations). There's still lot to be mentioned, I just wrote, what comes to my mind at first, so other cool brands are welcome

How Much Do Looks Matter When You’re Purchasing a Bike? - Pinkbike Poll
Best paintjobs out there, that randomly come to my mind is Specialized S-Works Epic (metallic), Enduro, purple Orbe Rallon, every Antidote frame with it's all-carbon glory, that i love, and most of Intense's Factory, mostly red/lime Tracer, black/gray/red Carbine and of course Recluse DVO edition. My personal favs are bikes in raw carbon, ti or steel, or painted in a somehow creative way

How Much Do Looks Matter When You’re Purchasing a Bike? - Pinkbike Poll
Oh, this question leads me to some other- why some bike manufacturers (like Transition) build so good-looking bikes in terms of frame shape etc, and then ruin everything with such old-fashioned, outdated, or just ugly paintjob (fonts, colours etc)? In fact, i personally think, that Transition frames looks better than Intense in case of shape only, but it is completely destroyed by paint, while Intense paintjob is soooo awesome! This thinking outside of the box in paint design is very appreciated

The Tuesday Tune Ep 20: Preload Adjustment - Video
@Drover: Yes, it's one of my points. Plus, shaft in air shocks is wider than in coil. Second thing: vectors of forces in frames cause some issues, as forces aren't parallel (or perpendicular) to them, so is there a way to avoid it? (bearings are being worn-out, stress on frame members etc.) Didn't know that pull shocks are ridden because of counteracting a shaft flex, but it seems very clever (more than rail- based suspension designs

The Tuesday Tune Ep 20: Preload Adjustment - Video
Well first of all, I absolutely love the tuesday tune! Great work guys, keep it goin'! I'm totally a bike nerd. mostly in suspesion- not only produts, but also philosophies behind linkage systems etc. However, and that is weird, i'm kind of every bike except mine kinda nerd, so I'm running 2006 26" XC bike, with full XT group and air shock. I even like my Avid SD V-brakes! (maybe cause i'm 125Ib guy, so almost everything locks my wheels and is powrful enough for the type of flat terrain i live in- Poland, 12 miles below the beaches of the Baltic sea). I switched to them from Hayes Nine and Simano deore brakes, that was too powerful in my opinion, and, as a poor engineering student I don't have money enough to buy some modern brakes with a proper modulation. Getting to the point, I'd like to suggest You a topic, that is barely touched: shock stiffness/flex and how do links deal with unwanted forces, that are applied to the bearings/ Let me explain what i'm thinking about for some time now, and what i can only imagine, how works (i quit being a bike mechanic two years ago, when i found a job in automatics/teaching/programming and machine vision systems- I was at a hospital for two months, so i'm unemployed now, but i work on my engineer degree, so after few months i'll b bak on trail, probably with my wallets not so empty as now :P) We can see a whole sea of coplicated linkage systems, and the forces on links are being transmitted on the frame mostly through the shock. Thats right. But what we can see is that those links are in some angles, that varies, as shock goes through its travel, sometimes changes at those angles are about quarter of a turn, so that is rather much. As the back whel is sucked by roots etc it creates forces that not only alter suspension action, but also create stress on bearings, and of course, shock itself. What gives me some headache in comparison between those two above is this, that link, that compresses the shock almost never compresses it exactly in the straight line that can be drawn between eyelets, it almost always compresses the shock, with a force, that's vector is slightly (or more often not so slightly) rotated basing on this line. This causes stress on bearings, bushings, frame elements, and ofc shock itself. I know that we can alter some kinematics by making use of this, but it's a comromise between desired characteristics and material stress. And last: as we know, shocks are being compressed, but those frame elements, that links, that pushes them, are also kinda try to bend them in some way, cause forces go in a lot of directions. Air shocks have almost always wide shaft, while coil shocks has that few milimetres thin shafts. Im almostust sure, that it can be bent to some point (alloys are rather elastic, so it comes back to it's original form after compression). Is it true? How this can alter suspension performance/ I saw some old Yeti DH models, that compressed shocks in straight line with a weird kind of rail or sth. What can You say about this problem?
