Jak zprovoznit bezdušové pláště na kole a jaké problémy vás u toho můžou potkat

Před pár dny jsem přešel na bezdušáky a dost jsem se s tím natrápil. Takže se podělím.

A trochu pankověji ve slovenštině:

 

How to Take MTB Photos that are Less Boring

Převzatý článek

Chances are you’ve been pedaling through some incredible scenery, pulled out your smartphone and started snapping away. I’m betting you’ve been pretty underwhelmed. You may have even captioned the photo “this doesn’t do it justice.”  The suggestions and tips in this article will have you returning from your adventures with less boring photos that you and your friends are sure to be stoked on.

Mountain Bike Handlebar Setup

Převzatý článek

As one of the two points of contact between you and your bike, setting up your handlebars and controls properly makes an enormous difference in creating an enjoyable ride. People frequently will hop on a new bike and go without giving this a second thought, but proper handlebar setup will differ drastically from person to person, and even if your mechanic knows what they are doing in this regard (I’ve seen more than one that don’t), chances are they aren’t the same size and shape as you, and don’t have the same riding demeanor as you do. If you have just received a partially assembled bike in the mail from us, chances are you will be going through this process yourself. If that is the case, get your bike fully assembled before performing this fine tuning.

How to Calculate Suspension Sag

Převzatý článek

Sag – it may only be a three letter word, but it plays a huge role in how your full suspension bike rides. When you sit on your bike, your rear shock will sink a certain amount into it’s travel – this is referred to as sag. The amount of recommended sag will vary depending on the type of bike that you ride. Typically, enduro/trail bikes fall between 25% – 35% recommended sag, while downhill bikes can be up to 40% recommended sag. At the other end of the spectrum, short travel cross country bikes are going to be closer to 20% – 30% recommended sag. These numbers are just guidelines though, and may vary depending on suspension kinematics, leverage ratios, and other factors. With the exception of downhill bikes, most other full suspension bikes are running air shocks these days. And many of these air shocks have laser-etched guides showing exactly where you sit in your travel, which takes the guesswork out of the sag calculation. Simply sit on the bike with your geared-up weight, and see where your sag ring ends up. Be sure not to bounce up and down, as this will not provide an accurate sag measurement. You can then adjust your air pressure up or down to hit your exact target sag percentage. But what if your rear shock doesn’t have those sag measurements etched? Or what if you’re trying to measure sag on a downhill bike with a coil shock? You can try to eyeball the percentage of sag, and generally that will work okay. But if you’re a perfectionist like us, “pretty close” isn’t good enough. Many of us here at Fanatik are pretty particular about the amount of sag we prefer, depending on which bike it is we’re riding. Calculating sag may seem daunting, but it’s actually pretty easy. I’ve broken it down into four easy steps. You’ll need a ruler or measuring tape with millimeters, a buddy, a calculator, and most likely a shock pump.

Nastavení odpružení vidlice a tlumiče

Hmotnost jezdce a jeho pozice na kole jsou určující parametry pro správné nastavení odpružení. Když na kole sedíte, vidlice a tlumič se stlačí vaší váhou, hodnota tohoto stlačení se nazývá SAG a lze jí snadno určit pomocí barevných gumových kroužků na kluzácích vidlice a tlumiče. Správná hodnota SAGu je mezi 25 %–30 % zdvihu u Enduro a AM kol, pro XC kola je to pak zhruba 20 %. Hodnota SAGu je samozřejmě individuální a její nastavení závisí především na vás. Nikdy by však neměla překročit 40 %. Pro příklad, pokud má vidlice zdvih 100 mm, 20% hodnota SAG bude odpovídat 20mm zdvihu.
