Looking at the Kona on the Web, the GT (LX/deore mix) seems better specced than the Kona (Deore). The J3 lockout shock has also received good reviews. Not sure of the weight diff though and this could be the dec factor. The Kona is given as a XC bike while the GT falls into the All Mountain cat.

The GT is quite heavy but I can say that about all entry level bikes falling into this category. Easy way to loose a 1kg fast is to change the tires, the front tire weighs in at 880g and the back is 710g. swap those for Larsens TT(450g each) with Stans Conversion(230g) and you'll save yourself more than a kilo since the tubs weigh 200g each.

Hey DR easy now on the SRAM! I'll have to whip your ass for that at the next opportunity! Interclub Fountains 28th May?

Thanks a mil!!!!

This might sound like a stupid Q, but what's the difference btwn 6061 and 7005 with regards to the frame?

Besides if I'm gona buy a bike I'd probably want to consider the best frame i suppose.

Ok I will be there smileys/smiley36.gif .

Leo read this :

Double-Butted 7005 Aluminum

7005 aluminum is an aerospace grade aluminum that is 5-10% stronger than 6061 aluminum by most measures. Double-butted tubes are specially drawn so that they are thicker at the ends of the tubes, where they are welded and stresses are highest, and thinner in the middle to minimize weight. The process of drawing and butting tubes also work hardens the aluminum. Work hardening is a restructuring of the material at the molecular level when the material is heated to a specific range, for a specific length of time, and stressed to a specific degree. Work hardening increases the strength of 7005 aluminum by roughly 20%. Double butted 7005 tubes therefore, are significantly stronger than equivalent weight plain gauge 7005 or 6061 tubes. Double butted tubing allows frame designers to build strong, but exceptionally light frames.

 

http://www.dahon.com/images/technology/sonus.jpgSonus Tubing

Sonus tubing further increases strength and torsional rigidity with a custom profile. Sonus tubing is used on the main tube of all Dahon folding bikes and is massively oversized with a flat base. Sonus tubing increases strength and torsional rigidity by over 30% compared to comparably sized oval tubes.

 

4130 Chromoly Steel

When it comes to "liveliness" and road feel, quality steel is still the material of choice for many discerning cyclists. A well-built steel frame can last a lifetime. Almost all steel framed folding bicycles are made from low-cost high-tensile (also called low-carbon) steel. Dahon only uses drawn (work hardened), 4130 chromoly steel, which is 60% stronger than high tensile steel. Because of our chromoly tubing's significantly higher strength, we can use thinner, and therefore lighter, tubing. 4130 chromoly is why our steel framed bikes feel so "right" and weigh less than many aluminum frame bikes from other manufacturers.

 

Puro? U6 Aluminum Alloy

Puro? U6 aluminum alloy is 25% stronger and 20% more fatigue resistant than traditional 6061-T6 aluminum alloy. We worked with the suppliers of this material to develop custom tubes for our SlipStream fork, the lightest aluminum fork on the market.

 

6061 Aluminum

6061-T6 aluminum is the workhorse of the bicycling world. It is used to manufacture everything from frames to stems to cranks. It is relatively light, plentiful, and easy to work with. Most aluminum frames are made from plain gauge 6061 tubing. All Dahon aluminum frames are now made using Sonus 7005 double-butted tubing.

What is really great about a forum like this is just how much one can learn by reading responses to other members' questions!smileys/smiley32.gifsmileys/smiley32.gif

6061 and 7005 basically states the mixture between alu and other metals to make the frame. If I remember correctly, 7005 is a little lighter than 6061, but not sure if you trade in the weight for rididity or the like.

I ride an identical GT frame and it is def. bullet-proof. handles like a dream (although it is a little heavy) but overall a great bike. the geometry is also real comfy!

There are a couple of schools of thought on buying a bike for a frame or for components: Some will say get a solid frame cause you can always upgrade components (which can work out more expensive than getting a new fully specced bike). Other say buy what you can afford, ride it till its stukkend, then buy a totally new bike.

Also, dont count out the new raleighs -they are highly specced and from reports, the frame delivers as well. Try to get as much advice from ppl who ride those exact bikes as possible.

And if in doubt, choose the one that you think looks the nicest - you have to love you bike and be proud of her, otherwise it'll sit on your garage wall, gathering dust instead of dirt.

I try to be open minded about this although I got 4 raleighs in my garage . One is a cheap RM3 bike and I am very happy with it . I only use it for relaxed rides while son uses the thing to race with and the hooligan has not managed to break anything YET . I buy Raleigh's because I believe it is value for money and don't like a bike that is not true blue !

And having said that I will disapear now !

I did this on my fuel 90 and shaved off just under 1 kg from larsen TT beaded to LArsen TT foldables with Stans.....so you will save over 1 kg if going from heavier tyres initially... love tubeless conversion, no puncture in 6 months and I ride in the eastern cape....... thornlands!!!
