  1. Sounds like a classic case of mushy shite. Thanks for the heads-up. Is it possible you were using long pull-levers though? From what I've read road brakes need short-pull levers, just checkin'. I guess I'm sticking with my BB7s anyway.
  2. Well, Avid BB7 *is* the route at the moment, I'm just looking for something with better modulation. I could be wrong but wouldn't dual-sided pistons be a refinement over single-sided BB7s? The fixed pad on BB7 needs to be very close to the rotor to work properly, so I get a bit of rubbing. I read some posts elsewhere of people bitching that BB7s are a PITA to set up compared with the Spykes, due to the conical spacers. The Avid mounting system is very clever as it's the only caliper alignment system that doesn't require facing the caliper mounts, as far as I know. It's never taken me more than a couple of minutes to align. I'm tempted to guinea-pig this one though...
  3. Been riding pretty much every other day, even on days of heavy rain. Finger to the weather Pallets are really a great help for learning. Dunno what it is, but there's something welcoming about a stack of pallets. I can adjust height and gap length which is also pretty awesome. I've tried various set-ups but at the moment I'm using a pile of 2x2x5 pallets, basically a big square platform for practising up to front wheel. I could get away with 1x2x5 but the extra surface makes everything seem less scary = more progress. I might get some more. If you are lucky enough to have a nice backyard I highly recommend getting yourself at least 10 pallets, they are awesome.
  4. Does anyone here have experience with TRP Spyke mech disc brakes? It's a dual-sided mechanical caliper, some MTB riders claim to be nicer than BB7s. I run BB7s front and rear on my mod and they do their job well, I'm just wondering if there are better options. I've considered hydros many times but I love the simplicity of mechs too much to give up.
  5. I live in Wuxi, China, and here everything's made of polished super-slippy granite (looks like granite, probably isn't). Back home pallets can be found for free in any skip but here they are harvested like gold. So basically a lot of nice obstacles are made of slippy crap and are not very rideable. After struggling for two years to find a decent riding spot, last week I went to the top of my block, just to check out the view. When I got to the top I was greeted by a door with a beefy padlock on it. Googled how to hack a lock without damaging it, works. Once on the rooftop, I witnessed this huge unused space. The perfect trails spot. Bought 20 pallets for about four quid each, and had them delivered to the underground car park. Getting them to the rooftop was possibly one of the most intensive workouts I've ever done, because the lift doesn't go all the way up. That was yesterday. My arms still ache a bit so I've not been able to test-ride the training course yet, but I'm hoping to go up there tomorrow. Here are some pics, best thing about it is the roof, which means I can ride even when it rains. I wonder how long it'll be before I get found out. I'll probably have to bribe the porter to turn a blind eye.
  6. What's the difference between the Crane and the Crane Pure other than price? I couldn't find much info even on POC's own website. I believe the Crane has an additional adjustment system on the back while the Pure is just the usual adjustable straps.
  7. Got my new bars installed on my mod today: 3.5° Upsweep 10° Backsweep 95 mm total rise 740 mm wide 7075 Alu This was easily the most fun ride of all time. The benefits I've noticed are: I was able to gap about 10 cm further right off the bat Vertical hopping easier and higher Better overall control Was able to pull my first front wheel landing + wheel swap Super easy to find balance point on rear wheel, it almost feels like cheating Less strain on back, shoulders and biceps when on rear wheel Higher bars means improves riding posture on rear wheel Bunny hops seemed less scary, easier to roll onto rocks and shit The total rise of my old high-upsweep Echo bars was actually about the same, but the new bars have far less upsweep so I'm able to set them up further forward whilst still providing a comfortable grip angle. In practice, this places the grips a lot higher than with high-upsweep bars, making the set-up feel like a super long stem. This kind of confirms my theories, I'm extremely happy with this set-up so far.
  8. Absolutely. When the elbows are close to the torso, the hands are almost completely vertical (say, 85 degree downsweep). An upsweep would be needed only if the elbows were above the shoulders.
  9. Neutral wrist position, you can see this guy pretending he's holding a pair of bars and his hands are naturally angled downwards. https://www.pinkbike.com/news/Tech-Tuesday-Handlebars-How-Wide-Affects-Your-Ride-2011.html
  10. I thought about this more yesterday and came up with two simple rules: For a fixed amount of backsweep, more upsweep => Rotate bars further backwards (towards the rider) for wrist comfort less upsweep => You'll be able to run your bars rotated further forward without compromising on wrist comfort. There. Upsweep and backsweep are actually just a single angle if you think in 3D, if you take flatbars, when you rotate them backwards the upsweep becomes backsweep. A slight downward angle would actually feel better on the rear wheel. Currently this could be achieved with flatbars rotated so they are pointing slightly downwards instead of upwards, but that would look way too wank. Would be interesting to see some bars where the bar has an overall rise to it while the ends are slightly bent down to follow the wrists neutral position (slight supination). This is the same as ergonomic typing keyboards which are "tented".
  11. Just noticed on the Arcade bars product page on Tarty: "Similar total rise to other handlebars - the difference is in the upsweep! More "rise" and less upsweep makes the "shoulders" of the handlebars much higher, which makes the part that most of you hands actually grip notably higher than bars with less "rise" and more sweep. This makes the bars feel much higher rise. (See extra picture for visual comparison to the ever-popular Trialtech High Rise bars.)" That's exactly my theory! I get the biggest callus at the base of my pinkies, because the pinkies are trying to do the work that the middle & ring fingers should be doing. The middle finger is way under-used with v-shaped bars. My new bars are not here yet though, can't wait to test and confirm
  12. Jamesb, what I've noticed is that a lot of stems are now only 150mm in length, so a lot of riders tilt their bars forwards to add a bit of length and hence leverage, which makes hopping on the rear wheel less strenuous. This is especially a problem on mods. I don't know what stem you are using, but recently I switched from 150mm 30° to 175mm 35° and it's night and day. With the longer stem I can turn my bars to a comfortable angle while still having plenty of leverage. You may also want to try thicker grips if you are getting wrist pain it may, again a lot of people go for super thin and in my case my hand pain went away with thicker grips. It's not always a good idea to "follow the elite". For bars, the only real solution would be to make several geometries available. As you say, there's no such think as a perfect handlebar for everybody, what works for me may not work for you. Two days ago I rounded up all the models I could buy easily this side of the planet (China) and made a little comparison chart, see attachment. Some values are not complete but the geo values are mostly all in. I really wanted to try something with more rise and less upsweep, and install the bars tilted forward to effectively have the same effect as a very long stem and give me more leverage, hopefully encouraging a more relaxed posture when on the rear wheel. Eventually I ordered myself a "SAW Riser 7075" bar, rise is a notch more than my Echo SL bars but with the lesser upsweep the hand should be positioned a bit higher. Since I plan to install them tilted forward it (following the direction of the stem), the reduced upsweep in theory should ease off some strain at the base of the pinky which is where I get the biggest callus at the moment, while the backsweep should feel rather sweet on the rear wheel. Will report back my impressions once I get them.
  13. Hi people, I'm looking to get a new handlebar with a higher rise mainly to act as an extension to my stem, currently running Echo SL alu bars that shipped with the bike. I've searched high and low and couldn't find much about this whole "upsweep" and "backsweep" business. I install my bars so that they feel most comfortable on the rear wheel. In that position I find the backsweep angle basically follows the natural grip angle of my hands, more or less. Currently most trials bars have a backsweep angle between 8° and 11°, with 10° being the most popular backsweep angle (8 out of 15 bars I'm comparing had a 10° backsweep). Due to geometrical considerations, longer bars require more backsweep (just imagine how awkward it would be holding a 1500mm-long completely straight bar). The effect of the backsweep is pretty obvious. And then we have upsweep. Unlike backsweep, upsweep angle values vary wildly across different handlebar models: out of 15 trials bars I'm comparing, upsweep ranges from 4° to 14°, and there is no clear popular upsweep value. It seems manufacturers haven't yet figured out what riders need? Is upsweep needed if you have a very long stem or a very high rise? I can see how the upsweep makes the bars feel nicer on two wheels, but I don't understand why the upsweep angle is different from, and in many cases greater than, the backsweep angle. The human hand has a particular neutral position. Associated with this neutral position is a particular neutral position grip angle, which is unique to each person and fixed (in other words you'd need some kind of surgery to change that), therefore it doesn't make sense using different values for upsweep and backsweep, since there can only be one optimal grip angle, not two, that will suit the anatomy of a particular hand, therefore both upsweep and backsweep should follow the neutral angle. The neutral grip angle and is actually very easy to measure, just grab a broomstick and see which way it points, then measure the angle using a protractor. In my case this angle is 20° (long arms here), measured to a line perpendicular to the length of the bike frame, with elbows bent at 90°. So the popular 11° backsweep is a bit shy for me, but tolerable. My problem with the upsweep is that, on the rear wheel, it forces unnatural wrist pronation, rather than letting the wrists sit nice and horizontal in the neutral position which is mechanically more efficient and therefore comfortable. Here's what pronation looks like (the opposite is called supination): (Link) So basically it's like grabbing a bull by the horns, you get the idea. In fact, on the rear a slight "downsweep" would probably offer more comfort on the rear wheel. I remember watching a video where one of the riders ran his bars with a controversial negative upsweep (his bars were effectively flipped around), maybe this is the reason? Is it possible that front-wheel moves benefit from an upsweep, while rear-wheel moves from the backsweep? I'm only beginning to learn front wheel landings so I'm not sure if that's where the upsweep would come in handy, and in that case, wouldn't it make more sense to make both angles equal? Maybe I'm overthinking this. What's your experience with different bar geometries? Cheers
  14. The International Olympic Committee (IOC) today agreed to add baseball/softball, karate, skateboard, sports climbing and surfing to the sports programme for the Olympic Games Tokyo 2020. If skateboarding was approved I don't see why trials couldn't, other than the fact that there are more skateboarders than trialsters because skateboards are more affordable. It's up to people with more leverage than us individuals, such as the UCI, to start making noise (they may already be doing so...). Trials deserves a place in the Olympics because (a) it's a proper sport compared with many already approved so-called sports such as golf, (b) it's fun to watch and, (c) it would be beneficial for bike manufacturers and riders alike, and (d) it's a highly contagious sport--I know very few kids who woudn't want to ride trials after watching another kid do it.
  15. I've always run stock BB7 sintered pads but I want to try organics. So I went on Google and it seems there are loads of third-party aftermarket BB7-compatible pads. It's a minefield, without having tried any of them I literally have no clue what they will be like, but I don't want to buy them all only to find that there are only marginal differences. I'm essentially looking for something with a little more "bite". I've read about EBC pads but I can't get them where I live, any other recommendations? Are Avid's own organics any good? Thanks
