I've had this bike for about 3 months now so the review is based on that amount of usage, pretty much every day.

Lets start with the frame. 100% 4130 Chromoly 20.5"tt , Geometry is excellent . Highly responsive and good to manual with. Its easy to get the wheel up and also pretty easy to keep it there. I have an Agent Orange one and the paint seems to chip off rather easy, but not too major. Integrated headset. Euro Bottom Bracket. Seat stay brake mounts. Removable Gyro tabs.

The Forks (Hoffman Uber) and Bars (Hoffman Jumping) are both 4130 Chromo, both feel very nice to ride with, no problems with either. The geometry of the Bars feel Very nice to ride with, but cant say much about them because its majorly personal preferrence.

The wheels, Hoffman Generator wheelset. Chrome Rear, Black front, Double walled rims. These don't have offset spokes which I was a lil dissapointed about but so far they have remained straight as an arrow even under a lot of stess. The chrome on the rear rim is still very smooth, no signs of flaking. And strangely the black on the front has not worn out much at all yet even with alot of front brakes been used, where as all other black rims ive had would have worn off by now. They have 14mm hollow axles, and a rear casset 11t hub.

The seat and seatpost, Hoffman Stencil seat and some hoffman post I cant remember. The seat is like soft leather or something all over which seems like it would rip rather easy but no problems with that yet. It has moulded hand grips for holding it "dugh". The rails have like ruler markings on them so you can precisely tell how far forward your seat is mounted in the post. The seat slipped for the first time today, will have a look why tomorrow but should be alright. Other than that neither have had any problems yet.

The Crank, Primo Powerbite. What can I say, everybody knows they are awesome, and so far have not proved me otherwise. The only problem Ive had so far is sometimes on my left down pedal it made a creaking noise, but I greased up the spindle and the problem stopped. No signs of bending or twisting yet so everything ive heard about them seems to be true. A very good set of cranks.

The tyres, Hoffman Skidmark 120psi. Great tyres, run very smooth on the seal when at high PSI, dunno bout when at lower psi because ive never ran lower than 90 in them. They are fairly difficult to get on over the double wall rims but that should be expected from a 120psi tyre. Only one flat tyre scince ive ran them where before I used to have dirt monsters which got them much more often. I have heard rumors that they blow out when you run high psi in them but I constantly run 110 and so far they have held up very well. I want to replace them with Hoffman Rotator 120psi so I am doing extra skids here and there to wear them out quicker, but they dont want to haha. They are very hard wearing tyres. Oh and one more thing if you manage to skid just right you sometimes can see the hoffman signs they leave on the ground.

The Pedals. Wellgo Sealed Magnesium. Possibly Wellgo V8s but not sure. Lets put it this way, wellgos suck. Ive already replaced them with JCs which has gotta say something. They creak and pop at the first sign of pressure, and there is just way too many pins in them. Stink design.

The Stem. Top loading Hoffman stem looks aftermarket coz its not the same as the one on the site. Anyways it looks really good, when I first got it it slipped a hell of a lot, I put it down to because it had no grooves in the clamp area but It has scince stopped slipping. Occasionally if i land a drop off bad it will slip with a really loud screech but most stems do that.

Drive Set up. Sprocket, Hoffman Dinky Sprocket 30t. Really nice little sprocket, runs smooth and so far is far stronger that it looks. Rear is some 11t driver, not sure what make or anything it comes with the generator wheelset. Chain is just any average chain, maybe a little stronger that the cheaper ones but I think its still to soon to tell what this will be like.

Brake Setup. Levers, Tech 77s. These are OK I guess, not really the type of feel I like. The have hinges which is good but once you start running them on the bend the lever gets really close to your fingers really fast. Other than that they are pretty nice, good stiffness and durability. The cables are just standart ORYG cables, not anything worth mentioning really. The Gyro is a Snafu Mobeus, really nice little touch for out of the box riding. Teflon lined bearings help it to spin really really smoothly, and its good at keeping out the dirt to. Easy to set up and adjust. The Brakes are Hombres, I guess they are pretty good for stock brakes, especially compared to tektro. Reasonably easy to adjust and pretty nice stiffness. Have needed to re adjust the setup a couple times, probably just because the cables are still stretching. The pads grip the rims quite well, very well if you can adjust brakes correctly.

Grips, Hoffman Mushroom grips. Great wear in them, dont leave a heap of rubber on your hands/grips. The ends of them are indented so they go over top of your bar end. Nice length. One thing tho is when your hands get sweaty they get very very slippery very very quickly. But I ride with gloves so this is not a problem for me and they offer plenty of grip.

Pegs, Hofman Chromolly pegs with UHMC kit. It comes with 4 pegs and the "UHMC" Part means Ultra High Mollecular Compound. Which is a very hard plastic sleeve that slips over your peg and is fastened on by like bar ends for your pegs. These make grinding soo smooth and quiet even on concrete. You can run the pegs with it off too if you prefer the loud metal on metal sound. The plastic seems to dent quite easy but I dont ride with pegs much so I cant really say.

I think that pretty much sums it up, the bike is Actually quite light, im not sure on the exact weight Hoffman doesnt say. I think it is an Awesome bike, designed with Professional riding in mind. If you can afford it you will not be dissapointed.
