@Toad

If I had to modify my seatpost again I'd do it exactly the same way. It is a little fiddly tightening the front bolt, but it was fiddly before I made any changes.

My modifications are as follows;
- M6 KCNC yoke at rear
- M6 KCNC yoke at front drilled out to accept M7 bolt
- Smud carbon cradle
- M6 Ti bolt to rear

I did try one of the M7 bolts without the knurled section but that made it a little too awkward to tighten the bolt so I went back to the standard part. I'd like to get a M7 ti bolt, but as they aren't a standard size they don't seem to be readily available, plus it would make it harder to tighten.

When setting it up it might be easier if the yokes are rounded, with the KCNCs I had to make sure that everything was sitting flush before I torqued it up. This is hardly a challenging task though.

That Smud carbon craddle is a thing of beauty. How can I get my hands on one here in the US?

I took apart my ISP seatpost clamp parts and weighed the individual pieces. Here is what I got:

Giant TCR Advanced ISP Topper parts:
craddle: 19 grams
yoke: 31 grams (the yoke is one big slab of metal)
bolts: 14 grams
Barrel Nut (Front): 4 grams
Anchor (Rear): 1 gram

I didn't pull the body off, because it wears on the ISP each time, and I am not replacing it anyway.

The yoke is kind of a no-brainer weight wise, but here is my only concern: The bolts on the ISP tend to lean. In other words they don't go straight up into the yoke at a perfect 90 degree angle. To keep from damaging carbon rails, I would prefer to get yokes that are rounded (like Parts of Passion). The front yoke will have to be drilled out, but the rear yoke can thread right in. My only concern there is that I will be screwing a titanium bolt into aluminum threads. Should this be a concern? Do you think the rear yoke will hold just fine? I guess I ask because the stock yoke is not threaded at all, but uses an embedded steal threaded cup shaped anchor.

The cradle weight gains are not huge, but that smud craddle just looks great and looks like it will be very carbon rail friendly.

There is quite a nice weight saving to be had. The KCNC yokes came in at 6g each and the Smud cradle was 10g, so that would be a 29g saving before touching the bolts. It might be worth considering your saddle position though as you're effectively removing the setback from the stock parts.

It looks like the ISP clamp uses exactly the same parts as the Vector seatpost (the bolts also have a bit of a lean going on). I've not had any problems with the titanium bolt and aluminium threads, I haven't heard of people having problems with seatposts that these yokes were designed for. I'd be inclined to agree that the POP yokes may be better suited especially if using a carbon railed saddle, that may be something I change in the future though it's working perfectly as is now.

For the Smud parts just send Piotr a message (http://smud-carbon.eu/index_eng.html). I've seen a few threads where American members have purchased his parts. I think he's a one man business so it can take a little while for him to respond to e-mails, but the quality of his products and the decent pricing makes up for that.

- Inner plate replaced with Fibre-lyte version (7g)
- Rothshek carbon jockey wheels (8g pair)
- Removed decals from outer plate using Carbolift
- Nylon bolts for limit screws

Mostly aesthetic changes this time, coupled with a general service including new chain, chainrings and inner cables.

I decided to remove the logos from shifters, rear mech, seatpost and crankset using carbolift. I had planned on including the frame and fork in this list but felt that carbolift didn't live up to my expectations as I had to resort to Gum's razor blade technique after the carbolift mearly softened up the paint/lacquer. This following a six week wait with extremely poor communication about the situation has left me feeling very dissatisfied with the company.

I had a few issues using aluminium nipples on the drive side so rebuilt the rear wheel with brass nipples for a bit of piece of mind, this did however add ~20g. Hence why the overall weight doesn't differ greatly since last time.

I've added a few more weights to my build list that I had neglected to weigh first time round.

It's been short lived though, 50km later and I've got a slow puncture in the front tub and the rear wheel has decided to unscrew two non-drive side spokes leaving the nipples floating in the rim.

Is it an idea to remove the red stickers from the rims? Looks better imho

Annoyingly they aren't stickers and I don't have the patience to take the wheels apart and go through the hassle of removing them with Carbolift.

I agree though it would look much better without them.

Red tape not a good idea.

this bike begs for black bartape

Remove the red tape, bike looks like a cheap hooker. Get a black one.

Maybe I wanted it to look like a cheap hooker!

I had to try Benotto tape as it seemed to be one of the lighter tapes out there, the only colour that was a sensible price and didn't require ordering from America was the red. Personally I quite like it, it stops the bike from being monotone.

Though it turns out that the weight was almost identical to the Deda tape I removed, so unless I find it amazingly comfortable I'll probably switch back.

Please stop posting any further porn. :shock:

About the bartape, I believe the Lizard skins bartape is pretty light and good. It's sold in all kinds of colours including black. :)

22mm tyres seem narrow for this time of year. The TCR frame easily accepts 25mm's, I'm very happy with mine.

How is the C64 saddle by the way? I'd like one for a classy & lightweight build but they're hard to find.

If the bartape gets replaced it will be with Deda tape. I've got a couple of rolls of black lying around, it's as light as the benotto that replaced it and really comfortable.

I've not had any problems with 22mm tyres, though when it's really bad out I ride my fixed gear which coincidently is using the C64 you mentioned. Here's a picture of it from the summer.

Image

Whilst the C64 is a completely different shape to the Smud saddle I find it to be of a comparative level of comfort. I'm still putting plenty of miles on it with no complaints and ride my short comute on it without padded shorts. I found mine on ebay, I've seen them pop up a few times so it's just a case of keeping your eyes peeled.
I'm a carbon saddle convert. I recently rode a few bikes with Fizik Arione saddles (which I previously thought were really comfortable) only to be infuriated by not being able to slid into different positions and found that after a short period of time I was really uncomfortable.

On the lightweight MTB I'm running a stripped SLR. I'm quite happy with that, maybe I should try it on my TCR sometime.
