I've been playing with this for a few years but not had the time to get stuck into it properly. I have two 4500/OZ frames and my idea was to build one traditional one modern. The traditional one I built but never used it as the frame was the wrong size. It sat unused until I swapped the frame with Colin for the size I wanted, ie large. Another year or so goes by and I've still not had time to do anything - why is life always so busy?!

Anyway, this weekend I did grab a couple of hours in the shed and finally made a start. I'm going to build the modern one first as I've got two other traditional Proflexs I use regularly so the variety will be interesting. Also I've invested a fair bit of money into the parts and they're wasting not being built up.

So this is the frame I swopped with Colin

This is the mockup I did with the new large frame I swopped with Colin

I'm updating the suspension by using Fox Tallas forks, adjustable from 90mm to 130mm. I figure 90mm should keep things standard and then I can play with the extra travel if I need it.
The rear shock is a Fox RP23 although I think in this picture it's my spare Fox Float R. The RP23 has 3 way pro pedal as well as damping control so plenty of adjustment to confuse there as well. For this shock conversion the bottom bushes for the swing arm are a standard size but the top frame bushes I machine down from an oversize blank set. The bushes are available from MOJO SUSPENSION. The shock is fitted up side down otherwise you have to clearance the frame a little.

So this Saturday I fitted a Hammerhead adapter so as I can run the Hope Tech X2 disc brakes I've bought for it. I've not done one before but it was straight forward and no problem. It lined up easily and the calliper lined up perfectly.
Holes marked for Hammerhead

I drilled through with a 1.5mm bit first and then the correct size before tapping the threads.

Then tap

When the Hammerhead is attached it looks pretty cool I think and really is a good fit.

There seems to be an unintentional Easton theme going on here. The wheels are Easton EA70 and were on sale so too good to refuse. I like the all black colour of them and think they match the frame well. I picked up a Easton carbon Monkeylite bar at a bike sale the other weekend. Again it was dirt cheap so I couldn't refuse.
The groupset is XT with 9 speed cassette at the rear. This is also my first try with Hollowtech II but it looks quality and is nice and light. Again the black and silver suits the build I think.

The forks weren't new and there's a slight leak in one of the seals so I've got to get that sorted next along with turning down the top bush set for the RP23. Once that's done I'll fit the crank etc.

Now I've started this properly I want to keep the momentum going till it's built. I don't get much time free and it difficult spending my only free hours in the shed when I could be out riding, but I'll try to keep on top of it.

Managed to get a few hours today so I machined the top bushes for the Fox RP23 rear shock. The new service kit has arrived for the forks so I'll change the seals and oil when I get my next hour. It's all coming together nicely.

Thank you very much. I'm away camping for a few days but Sunday/Monday I should get the forks serviced. More photos soon.

So Monday I got a few hours in and serviced the Talas fork. New low friction seals and oil change. The sliders and bushes are in excellent condition and they don't leak oil now.

This is how it looks with the fork and wheels fitted. Tyres are Maxis High Rollers exception series. Fork is set at 90mm here. I've not cut the steerer yet as I've not decided how many spacers to use yet.

I fitted the Monkey lite bars just to get a feel for how it will look. Gratuitous carbon and Hope photo..

This is with the fork set at 130mm. I'm liking the chunky look of this OZ.

The brake hose is cable tied for now but I have to get some proper hose clips. Front brake next and then the Hollow tech crank. Won't be long now.

Looking good Chris!

Love the wheels!

I Dremeled the brake cable guides out on the OzX so that I could have through routing on the cable casing.

Cheers Col. I thought of the Dremmel but decided against it incase I ever want to back to V brakes. I've ordered some Shimano Deore cable guides so it keeps my options open.

Got a hours in today. Fitted the Hope X2 front disc brake, XT Hollow tech crank, XT front and rear mech, XT SPD pedals, carbon seat post with Charge Spoon saddle. Also pumped the rear shock up to pressure and set the sag.
I've got the XT shifters to fit next and I need to buy a chain and some grips. The brake hoses need shortening and then that should be it finished.
A quick freewheel down the garden path and it feels good. The suspension needs setting up but feels very nice. The brakes feel super sharp!

I finished my OZx on Friday. I still need to shorten the front brake hose but it's all done apart from that. I took it out on a shake down ride Friday afternoon and it rocks! It's very fast and steers very quickly set at 90mm. I don't have a means of weighing it but it's noticeably lighter than my 4000 and 857.
For the last bit of the forestry I set the fork at 130mm just to see the difference. It all got quite bouncey but flew over some real bone shakers with ease.
Fair to say I'm very happy!
Full spec to follow.

Here goes with the spec:
Frame: OZx with Hammerhead adapter
Fork : Fox Talas RLC 90mm - 130mm
Shock : Fox RP23 Pro pedal
Head set : Crane Creak S3
Crank : XT770 Hollow Tech 2
Shifters : XT770 Dual action
Front mech : XT76?
Rear mech : XT761
Cassette : XT770
Chain : Shimano XT HG93
Bar : Easton Monkeylite carbon
Grips : HOPE SL
Stem : Tioga carbon
Seat post : Tioga carbon
Seat : Charge Spoon

Wheels : Easton EA70XC
Pedals : Shimano XT785 SPD

It's not super light but I didn't build it to be. It's my lightest bike yet and feels it to ride. The only scales I have are cooking scales and it's not that light! But I will get it weighed out of curiosity. Hope you all like it.
