Why don't you try a countersunk bolt with you topcap?


:D Yea, tried that but the carbon is only about 1mm thick, so no room for a countersink,

I now have a roofing bolt in there, cut down and its a little lighter than the original bolt :lol:

Just been re reading the 11 speed conversion posts with interest, absolutely amazing work guys, i am amazed :D However, just had a thought, has anyone taken an 11 speed setup and turned it into Sa a 9 speed? Sounds silly, but it would be a lot lighter than a standard cassette etc? Or maybe no advantage?

@rickysticky you could do it yes. Would there be an advantage? Not really. Close ratio gears is a fantastic thing, sure you could bash a few cogs of an 11 and call it a light 9 but personally it's not something I'd do.

Bit of an update too, recently I have been doing some builds for a "customer" who brought my Scott addict (link below maybe?) it's a early gen super six, full carbon frame. It was sent to me as a bare frame and he said "do what you want, send me the bill" so I put my imagination cap on, and ordered a crap load of bits. Picked up a second hand Red Group of a buddy cheap and set about tuning it, though not extensively.

The levers were stripped of the paint and the SRAM logo on the brake lever was hand filed out. This took AAAAAGGGGEEEESSSSS but looks subtle and cool. Next a gloss black vinyl was tastefully applied to the opposing faces and a layer of clear was done over top. All done.


Image

Next the cranks were stripped and a SRAM was hand cut from gloss black and applied, the chain rings were anodised black(er) and the final result is fantastic! Sorry can't find the chain ring pic.

Image

Since the SRAM was the plain old silver, I stripped the derailleurs and calipers and sent them for anodizing. They came back looking good. Cost me $20 although turns out the front derailleur is a weird type of / might not even be alloy as the metal finishers couldn't get it to work...?

The rear derailleur got the carbon cage stripped of all paint and some new pulleys ordered up. End result = bike Porn.

Image

Image

The bike then got some Alligator I-Link cables, I swear by alloy housed cables, love the stuff! Looks awesome too and reduces the need to tune often too. Frame got polished and cleaned about 10 times, she sparkles now. Wheels got rid of their awful stickers, a Superlogic post and 3T Rotundo Bar was ordered as well as a generic alloy stem that got painted, although I'm not happy so used my spare tho so to take photos. The bontrager Xxl caws were painted gloss black and look lovely, now I'm waiting on the derailleurs to come back as the cable grabber bolt threads which is a magnesium? Sleeve pressed into the body didn't take anodizing well so a new sleeve is being put in each to make sure there are no problems.

Here is the most up to date photo so far

Image

Also in the pipeline for me is a few frame repairs, a cracked top tube on a TCR and a snapped chain stay on a 6.9 maddone. The maddone will be stripped and custom painted so it looks brand new and sent back to its owner. The TCR will (if I can be bothered even fixing it) probably just get hung on the wall in the man cave like it has been for the last two years.


Also in the future another super tuned red derailleur. Custom cages and jockey wheels this time. Aiming for 80/85gm. More on that later. Aaaaandddd I brought a 29er lefty single speed for racing, and no doubt knowing me that will get some cool bits. It already has a cool as s$&@ -20 120mm Cannondale Factory Racing Team stem, courtesy of my bud Anton Cooper, which looks rad, no photo yet!

Anyone done some cool tuning lately?

Not technically a tune, but he's my latest project.

Occasionally I build bikes, custom bits, heaps of cool parts and just generally spending other peoples money. I was sent a 6.9 Maddone frame, with a clean snapped non drive side chain stay.

Image

Upon close inspection it appears that the stay snapped and then progressed to rush in for a hug with the seat tube and split it down the centre about 150mm (6" for our Imperial friends)

Image

So I decided to mould the chai stay so I can try to repair the frame with out altering the appearance hugely. I opted for this as apposed to just wrapping the split in carbon as I feel this will perform better than a cover up. The bike is to be relegated to town fixie or likewise so it's racing says are gone. Using a small container, I snipped the shape of the chain stay half way down each opposing side to create a mould to pour Plaster of Paris into. I filled the mould up to a point where it covered half the chainstay, hence becoming a half mould. Another was created on the reverse and then sanded to create a smooth finish for the carbon.

Image

Image

Note: it's easier to remove a set mould if the area moulded is covered in a plastic or something. I wrapped it in electrical tape which worked fine.

The damaged section was then cut free with my new toy, I'm a builder and allow myself a new tool every month. So I was excited to use it finally!

Image

Image

Next I stripped the surrounding area so that bonded carbon has something to grab.

Image

That's where I'm up to currently. I'll run a thick bike tube up the chainstay and out the BB with layers of carbon wrapped around the tube, but inside the chain stay. The mould then clamped together and the bike tube pumped up. I'll post pictures later on when it's done.

Any ideas on repairing the seat tube split? Epoxy together and hope, or wrap in a layer or two of carbon?

Very interesting, looking forward to see how this turns out.

I'd wrap the seat tube.

Yeah I think it needs something like that. Just don't want to make it look awful

Hi Weenie. The Sram red front mech has a lot of titanium. So that could have been the issue with anodizing it.

You could spray it or hammerite it very carefully and it will look perfect.

Did you see my lousy photos? I got my red rear mech below 90grms nearer 80grms but my scales are not very good like my camera work :lol: for an exact weight.

I pushed it quite far. I could take some more weight off but I want to try it out first.

Have you seen the selfmade thread on the light bikes forum. Some amazing stuff going on.

Nice work :thumbup:
