Building a hardtail FR/Jump bike

[gravityworx]

So I'm building an Identiti Mr Hyde frame up for all mountain playing and jumping.

Head angle is rated at 70 degrees with a recomended fork travel of up to 130mm, Head tube is way gusseted, so I'm throwing on the old Risse trixxxy set up at 6" to slacken out the head angle just a little more.
Then from there, 24" Halo Combats with 3" Contra up front and 2.6" Ception in the rear, Dia-Tech Anchor disk brakes, Gusset Pigmy chromo cranks in 170mm with prosecuter pedals and an MRP system 3 chain guide, S.O.D. Stem, Prison bars, Bastard grips, and a Prayer Stool saddle.

I know it will be pretty heavy for a hardtail, but with a 38t front and 8 speed rear, I'll still be able to make the up hills pretty well.
Should be a fun go everywhere bike.

??????? why go with 24's instead of 26's............:imstupid:

[gravityworx]

The 24s are more ridgid and with them I can run the larger tires.
The larger tires have a larger contact patch with the ground and that helps out quite a bit in the super sketchy steep stuff.

You're probably gonna end up with a really heavy bike thats not going to be flickable at all. If I were you I'd do 26's with a 2.35 rear and a 2.5 front tire and a 5 in fork, lose the chromoly cranks and prison bars. You'll get a bike thats a lot more maneuverable. If you plan on doing mostly downhill runs go for it, but if you want something a little more all around I'd build it lighter.

Why would you go for a 38T up front? Why not something like a 32 even?

[gravityworx]

I know a 38 with everything heavy is not right for a normal jump bike.
Maybe I should qualify the use a little.
90 plus % of my riding is free riding and dh orientated with the other 10 or so percent being split between the various up hill sections to get to fun stuff and the occasional XC type ride on it just because.
The bike is replacing a destroyed Specialized FSR frame that was getting 7" on each end. It had Sun Double Wides, all sorts of weight.

I like jumping rocks and natural obstacles. Over obstacles is sometimes a fun line to take, but then the landings can be at less than desireable angles etc and so over building everything is to make it basically bomb proof.
I wanted to build a burly hard tail that will launch easily.
It won't be nearly as bad in the air as my 470 pound snowmobile.

get a freeride/dh bike

so u destroyed an xc rig by freeriding/dh

ahhhh EURIKA!!!! you want a freeride hardtail... so go buy 1... you'd be very suprised at how durable they are w/out the cromo cranks and bars. There are places you can save weight. These bikes will do everything u want, but pedal much easier and have tested geometry and part kits.

I've got the money to build any sort of DH friendly bike I like.
Next will probably be an equally heavily built SWD Racing frame. They are chromolly and have over 8" of travel etc. That bike will be a pure dh ride and probably never be peddaled up hill.

This is the current bike I'm building though. It will be replacing the fore mentioned FSR / big hit type frame. It was used for everything from free ride, urban assault, you name it. It was just over 7" of travel on each end and was 51 pounds of fun.

For this bike, I wanted to build about as heavy duty a hardtail as possible and then go thrash on it. So I am.
Plain and simple.
It's all about fun and about building the bikes that others don't already have,
otherwise I'd be on an off the shelf bike like everyone else and I just don't do that.



EDIT:
Look at Identiti's web site, jeff da grom.
Mr. Hyde is a hardtail freeride bike

The build up is coming along nicely.
Got the drop outs bolted onto the frame and adjusted properly, the stainless headset pressed on, the fork and wheels on the frame, stem mounted, and the wheels on. The hard part was coming up with 2 - 5mm spacers for the front hub because it is a standard 20mm x 110mm hub going onto a Risse fork that is a 120mm spread.

Tomorrow evening I'm assembling the bottom bracket / crank set and mounting them with the chain guide and putting the derailleur and chain on and probably the bars, brakes, and shifter.

From there the biggest part will be adjusting it all up and then riding crap out of it.

I'm stoked. This is turning out to be a really cool bike.

Pictures are too big for the forum thing.

Now to just get the time to finish building it....
