Ahh, not sure about the fork length though.

Why didn’t you order 32 RLC’s? They suck with 160mm forks (sorry but its true, I’ve had both)

£400 a service? 😯

I thought Orange 5’s were for those with more money than sense. Specialized/Giant/Trek/Canyon/Rose all offer a great spec for the cash, backed up with a long warranty.

Why make such ridiculous comments

He probably thinks that because a bike has better spec it will ride better.

He’s the one missing out, don’t let it bother you.

I have noticed he pops up on every Orange thread posting crap.

X0 is top of the range and the higher the number the cheaper the price point and the lower the spec.

Except its not, the Trance/Anthem Advanced SL 0 is the top of the range.

I should like some sort of UN ban on white seatposts

Yep, white seat posts and bars should be made illegal and if you get caught using them you get put on a register.

Oh god

Try this.

White looks queer, stick with black.

Take the shifter window off and have them set up like this

The shifter is just where you need it, and the leaver is in the perfect position for braking.

WTF has it got to do with him. I would be annoyed too.

Dirt, Chainspotting and Chainsmoke.

No idea how long the red takes.
My twelve year old son did the black in about 90 minutes, is that longer or shorter?

He did it quicker than all of them!

We could also open a thread on unsuspended vs. suspended weight by the way…

There is no need, I have already provided a link with a formula showing that a pound on the wheels equals two pound on the frame.

Edit: quick question

Two riders, same terrain, wind speed, identical fitness, body mass, muscle mass etc

One has a bike that weighs 30lbs

The other has a bike weighing 25lbs

Who will be quicker over 10 miles?

You can do an air can service yourself in about 10 minutes, its hardly rocket science.

Read this article, nothing scientific.

And this about them switching to carbon rims

Roskopp cites multiple benefits of the carbon hoops for the team, including carbon fibre’s memory – its ability to bounce back from a bend rather than deform – the material’s help in resisting flats, wheel stiffness and lower rotating weight.

Now ask yourself why they are trying to reduce weight on a downhill bike.

Rotating mass in bicycle wheels has an insignificant effect, however often the myth is repeated.
If anyone can show it makes a difference, rather than claiming it does, I’m open to having my opinion changed.

TBF crikey me sober chum, so does non-rotating weight.

So in your world, power to weight ratio and rotational mass make no difference to speed or handling.

Hmmm, ok then….

Not bothering with reading the bumf above me, but this is my 2c.

Lighter wheels definately transform a bike.

I have a Giant reign X, and had some pro2s on ex729s. Went from them to Mavic Crossmax SX wheels, and lost about 600g. Also went from dual ply minions to single ply folding ardents (saving of approx 1kg)

Makes a MASSIVE difference. All of a sudden the bike accellerates really well, climbs much better, and also much stiffer (Which is suprising)

If you want to spend money, best way to spend it is on wheels. Otherwise, wear lighter clothing.

BTW, whoever is talking about how aero the bike.wheels are, this only comes into play at 20mph+

At last, someone with a brain cell.

Poor trolling Al

LOL excellent

Don’t do it, get the 32 RLC’s (and kashima RP23) instead. I guarantee you will have the Talas wound down to 130-140mm most of the time if you do.

If you think you need 160mm of travel buy an Alpine.

You will thank me for this.

I’m sure there are plenty more.

Buying a Saab is madness

Interesting, the 2012 RP23 I have on my Five is by far the best shock I have ever used, quite a bit better than the 2011 RP23 I had on my previous Five. Definitely no wallowing at all, if set up properly that is.

I give up.

I have one of these and its bloody brilliant.

So I was right, you haven’t any experience of the BOS…?

Mildred, I don’t need experience of Bos shocks, and if you read the thread I never said I did have.

I did say that I really don’t think there is much possibility of the VIP’R being any better than the 2012 RP23, and provided links to reviews in which the reviewers agree.

I do know for a fact however that this statement

All BOS rear shocks are built and tuned specifically for their user and bike to which they’re going to be fitted. RP23, on the other hand, are an off the shelf product with factory set tunes that you can then pay to have tuned to you and your bike.

Is absolute BS.

What is berm baby berm?

Its kind of like a pump track but down a hill, and its a lot of fun.

Like I said Northwind, selective reading.

If they actually read the article they would have an understanding on the subject, but like I said on page one….

I would make a contribution, but I think my time will be wasted explaining it. Clearly you two know better than the laws of physics.

I don’t think they have the brain power between them to understand it.

Of course people racing ride light bikes they feel fast, no one is arguing otherwise. There is an effect on speed, but it’s nothing more than placebo + weight itself.

LOL that is the funniest thing I have read today, nice one.

If you have proof, let’s see it, otherwise it’s just opinions.

There is plenty of proof in that link I gave, you two are just too narrow minded.

but the actual effect is small (as per bike weight).

If it wasn’t true, xc racers and road racers wouldn’t ride the lightest bikes possible, they would be happy to race 30 lbs Orange Fives and whatever the equivalent road bike is. Pretty obvious really.

I don’t know but I did the black, red, and blue in 04:20 in that order, including stops for food etc.

either way it’s pretty slack!

Yep, feels like the Titanic on anything that isn’t pointing downwards. I disliked it so much I bought a Five Pro instead.

skywalker, from your own quoted article;

Thus increased rotating mass may slightly reduce speed variations, but it does not add energy requirement beyond that of the same non-rotating mass.

Lighter bikes are easier to get up hills, but the cost of “rotating mass” is only an issue during a rapid acceleration, and it is small even then.

So, rotating mass is not really all that.

The miracle of light wheels (compared to saving weight anywhere else in the bike/rider system) is hard to see.

Really not all that.

Talk about selective reading…

Read the whole thing 🙄

.sorry, forgot; changing wheel weight is very noticeable, in that we/you/me can all tell that it’s changed, but it doesn’t have the effect in terms of actual, measureable performance that we assume.

http://en.wikipedia.org/wiki/Bicycle_performance#Advantages_of_light_wheels

Read that, it explains it all, the contents in your link are just someones view.

If we were on about road bikes then aerodynamics would play more of an important roll, but we are talking about mountain biking where you are constantly braking then accelerating. Aerodynamics will not help you climbing a hill, the speeds are too slow, whereas less weight will.

Change of direction is also easier with lighter wheels due to less inertia, something you do a lot of in MTB’ing and not so much of on the road.

Come on, don’t be shy. Explain the difference that 500g weight loss at the wheels will make in a 12 hour mountain bike race, Professor.

Consider the kinetic energy and “rotating mass” of a bicycle in order to examine the energy impacts of rotating versus non-rotating mass.
The translational kinetic energy of an object in motion is:

Where E is energy in joules, m is mass in kg, and v is velocity in meters per second. For a rotating mass (such as a wheel), the rotational kinetic energy is given by

where I is the moment of inertia, ? (pronunciation: omega) is the angular velocity in radians per second. For a wheel with all its mass at the outer edge (a fair approximation for a bicycle wheel), the moment of inertia is

Where r is the radius in meters
The angular velocity is related to the translational velocity and the radius of the tire. As long as there is no slipping

When a rotating mass is moving down the road, its total kinetic energy is the sum of its translational kinetic energy and its rotational kinetic energy:

Substituting for I and ?, we get

The r2 terms cancel, and we finally get

In other words, a mass on the tire has twice the kinetic energy of a non-rotating mass on the bike. There is a kernel of truth in the old saying that “A pound off the wheels = 2 pounds off the frame.”

There you go, young grasshopper.

You should have broken its neck.

I would make a contribution, but I think my time will be wasted explaining it. Clearly you two know better than the laws of physics.

I find smaller engines are more economical if you drive them like an old fart, but in reality you just accelerate harder to get the thing moving, making it the same or sometimes worse of fuel.

Worse than that though, the car feels like it is being powered by a rodent on a wheel.

Rotating mass in bicycle wheels has an insignificant effect, however often the myth is repeated.

Just checked out the new product pics on the Cotic home page and I think it is the most right looking 29er i’ve seen! Nice!

I agree, although the saddle is pointing down.
