The single-legged fork must truly withstand heavier bending forces than conventional forks, simply due to physics and asymmetricity. But because of its different construction, the fork is actually stiffer than most 2-legged. Pros The top is attached like a dual crown downhill fork, which is much stiffer than a single-crown. The wheel axle is one-piece with ...

If we assume that both models are at about the same price point, here is what you can expect: The hardtail will be substantially lighter than a comparably priced full-suspension bike. The hardtail will likely have a higher level of components and possibly a better front shock because of the increased expense associated with the full suspension frame. Unless ...

You turn it on when riding on smooth surfaces or going up hill to improve pedal efficiency. It's hard to know if you will need it in advance because without riding the bike you won't know how well the suspension design handles pedal bob (the energy lost by the bike suspension compressing under pedal forces), try and get a test ride.

First off, when riding over rough terrain you should be hovering above your saddle, not sitting on the saddle. This holds whether riding a hard tail (no rear suspension) or riding a full suspension bike. If you are sitting you have less ability to move your weight around, and therefore less control of the bike. When sitting it is easy for a large bump to ...

This choice really does depend on what kind of terrain you will be riding on. I'm also assuming you are intending to buy a quality full suspension bike. Anything under like $800-$1,000 USD, don't bother. Go hard tail with a good fork. The bumpier the terrain, the more a full suspension bike will help suck up the hard hits. You can really fly over rocks and ...

Specific answers to your questions: Does suspension reduce acceleration? Yes, for two reasons. Suspension causes bob, where some of your pedal power goes into flexing the suspension with each pedal stroke. That power does not spring back out and help you, it is lost. This can be helped if your suspension has a lockout function, which is like an off-...

The main reason I've seen is that police bikes are generic mid-price mountain bikes, and those almost always come with suspension. Even when they're decorated and packaged as "police bikes", they still seem to start out as mid-price generic MTBs. This comes from the requirement that they be reasonably rugged, able to have police kit bolted on, be reliable, ...

This fork setting exists so that the fork can be customized to your weight (major reason) and riding style (minor reason). It's simply the initial compression of the internal spring in the fork. The more it's compressed, the stiffer the fork will feel. Bigger preload compresses the spring more, and so it's best for heavier riders and/or people who need/...

You might find a suspension seatpost to be comfortable, but a suspension seatpost is not a substitute for a full suspension bike. The purpose of a suspension seatpost is purely comfort (though as mikes mentions, not everyone agrees that they achieve this goal), where as the purpose of a full suspension bike is first and foremost control. Suspension on the ...

Let me introduce you to the term 'Bicycle Shaped Object'... A 'Bicycle Shaped Object' (BSO) is not to be confused with a real bicycle. You get them in department stores, catalogue shops and supermarkets. They look like bicycles but they are not. Some BSOs come with 'full suspension' and this is the older patent-free design that gives 'pedal bob' - as you ...

Although this isn't explicitly part of your question, I'll go ahead and throw it in as it's one of the most important factors to consider in terms of increased suspension if you plan on pedaling your bike- the basic principle behind propelling a bike is to convert a mostly downward force (pedaling) into forward momentum (the drivetrain turning the back wheel ...

There are a couple of reasons. The KISS Principle If anything vital breaks while you're touring and you can't fix it on the spot, you're stranded. You're too far from home to call your mom for a ride. Unless you have a spare for the broken part, your options are some DIY jerry rigging and/or praying that someone with a truck comes by who will carry you and ...

Apart from going the high-tech route of a front suspension with lock-out, you can also try to get wider tires. The slow-down of wide tires is not that big, but they naturally even out high-frequency bumps. The wider the tire, the smoother your ride gets on the rough roads. Maybe, that's all you need.


15

Bouncyness* may not be the appropriate term for the behavior you need from your suspension. Suspension has two main functions: Shock Absorbing and Dampening. Shock absorbing is what the fork does by compressing, allowing the wheel to travel upwards. In this process, kinetic energy from the shock is used to compress either a coil spring or an air spring. ...

Benefits of suspension forks (city/gravel road use): Remove chatter from bumpy roads Take the jar out of major bumps Better traction Drawbacks of suspension forks: Entire bike is heavier, leading to a less agile bike. A bike with suspension (all else being equal) will hit more holes and hit them harder. It will also climb like a pig and accelerate ...

Suspension is a well-established concept nowdays, and is not bleeding edge. Police bikes will be serviced routinely, and all the preventative maintenance will keep them ready to ride and perform as expected. I agree that additional weight will slow them down a bit, but a cop on a bike isn't going to be chasing down cars. At best they will be operating in ...

Even if you're regularly riding up and down kerbs you don't need rear suspension. If you did, people wouldn't ride hardtail mountain bikes on the trails, where drop-offs considerably higher than kerbs are normal, as are step-ups. And even with my limited skill that's all possible on a hardtail (nothing massive). Suspension forks add weight, and this will ...

Less expensive forks have a mechanical lockout. This type of lockout is only usable when the fork is unweighted. Think of it like trying to deadbolt your door when it's still ajar. Higher end forks- coil or air- use a hydraulic lockout. There's a lot going on inside them but to simplify things a bit, there are two valves in the damper of most mid-high end ...

Mid range touring bikes come with shocks because because mid range consumers will buy them. Department store bikes come with full suspension because people buy them. High end touring bikes don't come with shocks because high end consumers don't see the value. A bicycle does not need to be used for how it is classified/designed. I use a cyclocross with ...


12

Short and simple... Nobody with the cash to spend on a high end touring bike thinks they are worthwhile. Given the increasing specialization in the bike market, they only reason they don't exist is nobody will buy them.

You definitely don't need rear suspension: that's for serious off-road riding. For riding on the road and the very mild hardly-off-road-at-all riding you're proposing, rear suspension just adds a lot of weight and it flexes as you pedal, which uses up some of your power. Also, it's a complex system that gives you about five more things to go wrong on the ...

Modern suspensions have a valve inside, and when the suspension moves, the valve moves inside oil, and the oil is forced to pass a very narrow opening. The size of this opening is different depending if the suspension is compressing or returning. Usually, there is a spring which lets the oil flow more when it compresses, and less when it rebounds (the ...

I'd say the biggest change is the shift from coil and oil shocks to air springs. Even at the cheaper end of the market most bikes designed to go uphill will be using air shock suspension. Air suspension is lighter but in the past has performed less well and been more expensive. Over the years price has fallen and performance has improved. The other big ...

I'm told rear suspension is not a must have That's right, there is even a category in Down Hill races called "hard tail", for people with, well, hard-tail bikes. And they kick some serious arses with those bikes. What is the ride like without rear suspension, what do I lose? You have to pay attention where you put that rear wheel on. With a full, you ...

There is one more reason to add. They will be on the bike all day, every day, 4 days a week (or more). Around here, bike cops are used quite a bit "down town" and at almost all events in the area. These cops have to ride their bikes for hours at a time. A normal shift (around here) is 4 9 hour days, then 3 days off. By comparison the Tour de France's ...

First off many forks have a remote lock out as an add on. Fox and rock shox especially. If it has a lock out, a remote lock out is likely available. Secondly, a nice fork that is set up properly for your weight shouldn't need to be locked out all that often. I have had a variety of great fox and rock shox forks that i only lock on long, steep, grueling ...

The advantages of a front suspended bike is that holding the handlebar in off-road downhill is way less tiring and comfortable, and above a certain speed (and if the fork suspension is good enough) you will have much better grip on the ground and steering/braking control. The downside is that if you can't lock the suspension you might feel it's absorbing ...

I'm assuming this is your bike and you really mean that you've removed the fork from the bike as disassembling the fork isn't really something you do by mistake. The specs I found say that you've got a threadless stem and sealed bearing headset. This is easy to reattach. There are 3 or 4 bolts you need to be concerned with. One right at the top, that goes ...

There are seatpost shims available for a few dollars. You should get them easily in your local shop or online. I use an aluminum shim in one of my bikes with exactly the dimensions you need, it works flawlessly and looks very clean. I got it for about 3.50 € (5$).

I've serviced the brain on my 2006 sworks stumpy several times over the past few years, mostly because of the crummy turnaround times from spesh, and the fact that it never makes it through more than half a season before losing lockout etc. And the fact that I'm a mechanical engineer and stupidly tear into anything that breaks thinking I can handle it (half ...
