A dream of mine. Not a BMX, but has some BMX parts

Aloha.

So as many of the regulars will know on here I have what used to be a PK Ripper fixed. It's what I do anything more than a potter around on. I got it in 2017 NOS from 08 and over the past 7 years had turned it into this.



Everything but the frame has been replaced with better, lighter components. The bike cost me 300 quid back then from Germany. The tyres (white, eww) were dry rotted and one of the wheels was damaged. I didn't mind, as 700c wheels are reasonably cheap unless you go high end.

Last year I added the bottle cage and the new rear wheel and ran into some issues. I had to drill the brake lower, and add extenders to the pads. A real bugger tbh. If I brake hard I reckon I would ruin the brake tube, and the bottle cage mounts were very hard to get in (rivnuts). As such for many years I have been on the look out for a new frame.

I wanted carbon, but heard it is stiffer and harder than alu. Like, the ride. With the new wheels and tyres on it smashed my ring hole to pieces, so that was the last thing I wanted. And then this happened for 525 quid about a week and a half back.



Rides like steel, doesn't corrode and the best of all worlds. It seemed like an awful lot of money but I did not realise that frame cost 1799 pounds plus VAT when it launched in 2017. It's new, unridden and unused. So I got it.

I knew that a lot of the parts would not fit. The steerer tube is also taller, and I had a lot of orange parts that I no longer want to use with it. I had started adding in splashes of red last year (chain, pads which I will no longer use as the frame has cable guides that won't rip your shorts) and etc. So, I bought this kit for the rear wheel as I am changing the gearing back to where it was before last summer.



44t and a new conversion kit for the 7 speed freehub. It's a 16t cro mo by Box.

Another part I wanted to use (finally after 18 months) was the BB I bought that I could not find the bolts for. It's Ti (axle and body). Problem is when I went to see how it fitted it didn't. Turns out the threads are Italian (weird, never used) and yeah.



Thankfully the threaded ends come bearing holders are removable, and 31mm ID. So I just bought another ISIS BB to use for the ends.



The seat post and clamp I had on the SE are no good. New frame is 31.6mm post (not 27.2) so I got a new post.



And then all of the same Hope stuff I had already in orange, but in red  :LolLolLolLol:





A seat clamp that will fit the frame.



And a red replacement top cap for the Hed Doctor. It replaces the star nut. This was a relief, 'cause it was about 25 quid. A new cap in red was 6.



I then began stripping the bike with the very limited tools I had.



Seat and cables off.



A new replacement stem in red. This was tricky, as the bars are like a BMX (22.2) with a 1-1/8 steerer. Turns out Box do a race stem that fits the bill.







I then needed some carbon gripper paste.



And copper anti seize.

Midschoolfool:
OK so with the BB issue somewhat resolved I ran into another issue. The frame has vertical single position dropouts. This means I will never get the chain right. After some research I found this.



Now what I need to do is remove the upper part and just use the lower arm, spring and bolt (frame has a hanger).

Then another issue. I forgot I respaced the axle on the rear wheel to fit 110. It should be 130. So I grabbed the cheapest axle I could find for parts.



Thankfully I did not cut the axle down or alter it in any way. I ordered two chainstay pads as the bike takes a battering bringing it up the stairs. I got around this on the SE with PPF and some stickers, but yeah it has taken a smacking.



New grips. I prefer lock on now due to carbon bars.



Talking of which. Remove, remove old grips, clean and weigh  :LolLolLolLol:



They weigh SFA !



New chainring bolts in red.



New bottle cage (the most expensive one I could find lol)





And a new bottle. Ketchup any one ?  :LolLolLolLol:



So last night I got the stem and fork off (finally) and ran into another snag. When I attempted to fit the headset bearings I realised they were too big. FFS. Turns out FSA make 41mm bearings (not 41.8). Why the F do companies do this sheet? So after more head scratching and research I ordered a pair of 41mm bearings.



And this is where I am at.

Midschoolfool:
I decided a few days ago I was going to redo the clear on the rear wheel. Maybe glossy, but deffo real 2k. We will see. The rear decals will be cut from this, on a black background (so edges)



I think that will look pure mean. I also got some PPF in satin. Ti does mark, there are a few tiny marks on it already.



I also realised I could reuse all of the nice parts of the Jagwire cables (these noodles in the pic in the box here)



So bought a cheaper cable kit.



I only need the outer and one inner.

Mikku:
A new build? I'm in!! Aloha indeed! :daumenhoch:
