awesome job w/ that seatpost and saddle. for the saddle, did you basically cut / tear the leather and padding off and then clearcoat?

Thanks.

The saddle was my sons, he had crashed and damaged it so I had it off him and took the cover off, its really smooth under it, so not much sanding on top was needed.dremel the cut outs and smooth off with wet wnd dry paper and I used car type clear lacquer. There is a little stub where the injection of the carbon moulding process in the centre but as I had cut the middle out I wasn't a problem, I have since cut out the back off the sadddle as on the last pic and its now down to 110g, the stripped cover weighted 30g.
Its very comfy with the centre cut out as it flexes alot so its not stiff and hard.

The seatpost is now down to 156g with more material taken from it, I wanted to get it down below Kcnc one.

I think it a nice weight considering the cost(free to me) and the weight of other saddles at that weight.

What a great job you've done to the bike. May I ask what tool you use to shape the seatpost cradle? Thanks.

Hi I used the off cut from the cut carbon steerer tube, its the right size then just cut in half, the slots were then ground cut to size, all just with a dremel tool cutting discs and various attatchments the same size as the rails.
The top of the post was also dremelled for it to sit on, you'll notice the thick piece of alloy still left from the cut off clamp, that must weight a bit so i got a hole saw that was almost the same size as the ID of the post and bored it out. It also took a few thou' of the wall lightening it even more.
I'm please how it turned out, lighter than the Kcnc one I was going to get for alot less.

I have only ridden the bike a few times but its very different compared to my old alloy framed bike. Being only 14.6lb very light, stiffer, soaks up road buzz and climbs very well always heading for the hilly route.
I love the frameset looks better in the flesh and great value.

cheers.

Thanks, I like to do things like that always trying to find ways of lowering the weight for less or free. Finding it hard now to cut more bits off nothing left that hasn't seeen the dremel, so it's back to changing parts now to shed more.

Few more tuning mods.
Removed Mavic Ksyrium wheel stickers.

Ritchey WCS wet look stem stripped and cut out front cap.

Bars with the same stripped treatment.

Shift lever clamp lightened with Ti bolts and grinded clamp.

The stripped bars and stem look better with out the wet look and save some weight too. It's anodized under the gloss finish which meant no further finish was needed. I sprayed the front cap satin black for that all important stealth look.
Happy with the wheel stickers removed too, I wasn't sure how it would look, but think it look better with out them.
I was thinking of getting carbon clamps but the would be too costly to get here so i decided to tune them for less. bolts were from Pro-bolt and weight 3.5g compared to 7g per clamp .

Bike is now 6.55kg :thumbup:

OK, I just had to respond to this because this is true weight weenie and its core, hunting down those grams everywhere you can find them.

Thanks for sharing your process and obsession.
