Rick

Is 30.5mm correct for the ADDICT's ISP?

Addict ISP is 30.25mm

Does anyone know which replacement clamp I need to order from Ritchey so these rails fit?

The standard clamp is for traditional round rails, but my flite has ovalized titanium rails so it's not working.

Their parts listing says Selle Italia's typically use 8x8.5mm rails

Though, at least as far as I can tell with my simplistic ruler measuring device, they appear to be closer to what Ritchey says Fizik's rail dimensions are (7x9.6mm)

The parts say they're for carbon saddle rails, but these are titanium so it's a bit of a moment for me.

Many thanks if you have any idea. I've called a few Scott dealers thinking they may have faced the problem with Addicts, but no luck so far.

The saddle in question:


edit: Thanks mods for the move, I missed this thread.

I think you either need this

or this

http://www.wiggle.co.uk/p/cycle/7/Ritch ... 360043169/" onclick="window.open(this.href);return false;

I have a flite kit carbonio and my LBS have ordered one of this for ritchey stubby.

Yep they are perfect if you have carbon railed saddles, however mine has Ti rails and so I'd need the 7x7 mounts, plus the part that sits between these clamps and the underside of the rails

After looking at the Ultimate seat post for cutting down, I decided against that option, on the grounds of not being sure it'd be up to the task with my weight and intended use, plus the cost.

Looks like I'll have to buy a Ritchey WCS 1-Bolt regular seat post and just use the fittings on the stubby to get a complete set up, expensive but not as expensive as the other options

I called up Pro Net Cycling and they were very helpful. It seems like it is the 7x9.6mm adaptor that's needed for the oval Ti rails.

Are there torque specs for the stubby (mine is a stubby aero) for is that for the frame manufacturer to determine?

beeseebee,

Torque is a funny thing. please read here.

Mcfk on order! Shipping middle of March, I hope.

This has been a helpful thread. I figured since I have gone on an endless search to find a reasonably affordable light weight ISP head that I would post my findings.

My search ended in ordering the new Woodman IT Ti Head. They claim 95g with a carbon cradle and Ti hardware. I'll try to remember to report back with weights after I receive it. I intend to use a carbon railed SLR saddle, so hopefully the clamp and rails will work together.

Here's a pic courtesy of BTI:

It might be ok but I don't think Selle Italia would approve that for its carbon rails.

Perfect! I don't see that on Woodman's site. Can you please share where you got it from?
Got it: http://www.bti-usa.com/public/category/ ... =12#WN2981

I ordered from Adrenaline Bikes. (http://www.adrenalinebikes.com) The website is a little slow and you can only find it on their site by searching all Woodman products, but it is there. I figured $85 isn't bad for the weight (and the fact that I desperately need one!). I'm sure that any shop who can order Woodman products can probably get them.

BTW - I have a 34.9 Ritchey stubby if anyone is interested...

Update - Adrenaline Bikes doesn't have any more and the US distributor is out of them... My search for a 35.9mm seat mast head continues!

I got my 30.4mm MCFK stubby (http://www.mcfk.de/ISP.html) a few days ago ... for my Scott Addict. Was hoping for 64g, but I mine is still a svelte 73g. It replaces a 131g Ritchey stubby.

Has anyone "tuned" a Ritchey Stubby? Perhaps some holes and Ti bolts to get it down to ~100g

Sure...
