Duke 300 for BB7, Duke 300 for BB

BB7 is the king of the line disc, its feel is lighter than the V brake, but also softer, if the debugging is good, even has the general feeling of the oil disc, the braking force is certainly needless to say, quite sensitive and powerful, sometimes even more powerful than the general oil disc, its sensitivity also makes the feel good, very smooth; Compared to the V brake, the BB7 is stronger than its braking force, feels better than it, and is not easy to break, basically less maintenance and replacement of brake pads, and BB is also easier to debug than the V brake!

BB7 is the king of cable discs, the difference is that it is more sensitive and easy to use. Not afraid of rain.

BB7 feels very linear (that is, relatively hard), there is an obvious demarcation point when pinching, pinching the brake handle before the demarcation point is almost not forceful, and it is difficult to pinch it again when it reaches the demarcation point, this demarcation point is the point where the clamp and the disc are in contact.

The braking force is related to several aspects, and not all BB7 braking forces are the same.

1. It is related to the force of the hand knob (this sentence is nonsense).

2. It is related to the material used in the order plate (brake pad), the braking force of the resin is the smallest, the semi-metal (metal resin mixture) is stronger, and the metal is stronger. I don't know how to use ceramic to make pieces or anything like that.

3. It is related to the radius of the disc, the larger the disc, the stronger the braking force (although it is said, it is not recommended to change the large disc).

The rest is welcome to be added downstairs.

Ahem. This ,..Anyway, BB7 is definitely better than V-brakes. Lightweight in the hand. It's definitely faster than a V-brake. Welcome to exchange. Ha ha.

I just want to say =. = Your V brakes with disc brakes seem to be changing things =. =

Just got the Duke 300 at 1pm today. Xi'an**1698The configuration is basically the same as the 2010 Duke 500, the most important thing is that the 300 is a V-brake hub You can't upgrade the disc brake, it will be very troublesome to upgrade, and you have to change a lot of things.

If you don't consider upgrading the disc brakes later, the 300 is a good choice.

BB7 is very good, a fighter in the line brake. Someone upstairs said that 500 on BB7 was a waste, and I thought it was wrong.

I don't recommend buying a bargain for this thing with brakes. After all, the quality of this thing is related to the safety of life.

Personally, I don't think it's necessary... Because like the LS, I don't have a good evaluation of the Duke 500, because I've also ridden that bike, and the BB7 performance won't talk about it, but I always feel that it's a bit of a waste on the Duke 500, after all, the Duke 500's shifting, transmission, fork and BB7 are a bit out of place, and it is recommended to either ride the 500 or change the bike.

Any car on the B7 is good......

But all aspects of the 500, such as the crankset, frame, etc., are not tough (didn't come up with a good word......Although it is a disc brake axle, but this car modification should not go too far, save money to change the bar frame of the challenger, and the modification space of the car is large (I mean that the modified car does not change the shelf).

.The wheel change includes hubs. Steel wire. and circles. If nothing else is broken. You just need to change the hub.

If you want to improve your bike's ability, you can consider a direct wheel change.

"Hard-working is nothing more than wanting to increase strength, and you can modify it from the following aspects:

1.Forks. XCR** is cheap, feels good, but not as strong as XC28, has high strength but feels a little hard (in fact, it is the old DART2), and I often have no big problem flying off-road

2.Crankset. It is recommended to use a high-grade SHIMANO or FSA crankset, which is strong enough to exert force, and the low-end crankset is generally soft

Most high-grade cranksets use a splined bottom bracket

If you buy a hub without changing the rim, you have to disassemble the original wheel set and rearrange it, which is very troublesome

If you buy a whole wheelset, you don't have enough budget

What year is the Duke 300?

1000 yuan budget can be considered to change the fork first, such as about 350 yuan of Santuo XCR or a slightly more expensive Rockshox XC28, the landlord's weight play XC28 is no problem, XC28 sealing is better than XCR.

The rest of the money can be considered to change the hub, such as the XT hub of Shimano, the moistness will be more than a century higher than the original one on your car.

These are the obvious improvements of the road press, since the budget is limited, there is no need to consider the dynamic transmission and transmission system. If the 300 of the 13 models is the first thing to suggest is to replace the broken wire disc

How can a car of this grade have a lockout function? The mountain bike front fork is originally used for shock absorption, and it will definitely be discouraged, if you want not to lose force, then use a hard fork.

In fact, the Duke 300 you will feel that it is still a challenger when you ride it.

1. UCC CXR advantages.

1. The frame of Duke 300 adopts a new coating design, and the frame applies TFS pipe processing technology. The vehicle is equipped with a Shimano 24-stage shifting system, mechanical disc brakes, front and rear alloy quick-release hubs, aluminum alloy suspension forks and chainring cranks, and auxiliary handlebar design. The rear triangular upper tube is also made of special-shaped flat tubes, and the lower tube is no longer used with frog legs, and the now popular flat tube type is used to increase the rigidity of the frame; The frame sizes are 15, 17, 19 and 3 colors in three classic colors

Black, white, red and an elegant grey. In addition to its beautiful appearance, more importantly, its strength has been greatly improved.

2. Aluminum alloy forged handlebar design provides more control methods and improves comfort, and Shimano integrated control lever makes your handlebar more concise. The transmission system is a Shimano 3*8 24-stage shifting system.

3. Disc brakes have become the new trend of modern mountain bikes. Its advantages: strong braking strength, good braking performance in harsh environments, aluminum alloy quick-release hub design, no need for any tools to disassemble the front and rear wheels according to your needs.

But before you ride, it's important to check that your quick release is locked.

Entry-level sports mountain bike, this bike from Merida, is of acceptable quality, suitable for fitness riding, and short-distance travel.

Pick 3 has not been put on the oil dish!! Pick 5 standard equipment on the Yanhao's oil dish!!

It's not good, because picking 300 is not much better than Gong 600, it's just a level higher, the oil disc can be changed, the transmission is still forgotten, just go directly to a better one, pick 300 oil disc seems to be more than 500.

There is no need to upgrade the Duke 600, the configuration is quite harmonious.

When it's time to change bikes, change to challenger.

Merida's frame doesn't change, the basic thing that changes is the livery, and the kit is occasionally upgraded. It's up to you to see what livery you like.
