Titanium Mountain Bike Frame
admin | Monday, March 29th, 2010 | No Comments »
A titanium mountain bike frame provides a combination of stiffness, strength, durability, and lightness to cyclists that can not be found in other types of mountain bike frames. The top-quality alloys of titanium frames are just as strong as the highest quality alloys of steel frames. The larger the tube is, the stiffer the titanium frame will be.
Normally there are two types of alloys that a titanium mountain bike frame will come in. The first is classified as a 3Al/2.5V alloy, which is three percent aluminum and two and one half percent vanadium. The other is a 6Al/4V alloy, which is six percent aluminum and four percent vanadium. This type of alloy is stronger then the 3Al/2.5V alloy, but it is also a bit more expensive.
A titanium mountain bike frame is an excellent choice for bigger riders, as it is a very strong frame. This type of mountain bike frame is also extremely light and also offers the added feature of being rust proof. One of the most popular titanium mountain bike frames is the Charge Duster titanium frame.
The Charge Duster titanium frame is one of the newest offerings in frames from Charge Bikes. It features 3Al/2.5V Seamless Tange Ultimate Butted titanium tubing. The frame is built to be able to withstand more abuse than most of the titanium mountain bike frames currently on the market. It comes with a custom machined tapered head tube and a forward facing seat tube slot.
The Charge Duster frame also features custom Investment cast dropouts with a disc mount. This frame allows for massive mud clearance and is available in either black or white. It also comes in sizes small, medium, and large. The small frame weighs in at 4.8 pounds, with the medium weighing 5 pounds, and the large being 5.2 pounds. The frame geometry is similar in most respects regardless of the size of the frame.
The head angle, seat angle, seat post size, seat clamp size, front mech size, BB shell, and CSL are all the same for the small, medium, and large frames. The difference in the frame geometry lies in the head tube length, top tube length, and seat tube length. The small frame has an 11cm head tube length, while the medium is at 12.6 cm and the large is 14.1 cm. The top tube length is 52.6cm on a small, 55.5 on a medium, and 57.5 on a large. The seat tube length on the small model is 41.5cm, with the medium being 46.6 and the large being 50.5.
A titanium mountain bike frame, such as the Charge Duster, can be a quality choice for those looking to build their own mountain bike, or even those who just simply want to replace their frame.
