Carbon Stealth Groupset

[lo5707]

My first 'proper' post on WW - hope you like it.........

This is my mix and match groupset for my first WW project - A carbon stealth build - Tuning almost complete but some hopefully respectable weights nevertheless. Sourced all the bits from the bay pretty cheaply then tuned and sanded where my currently limited skills allowed.

My main aim was to achieve a stealthy matt carbon 3k finish rather than uber lightweight - but it comes in naturally light anyway:

Crankset - Tuned Stronglight Helion with Fibre-Lyte Chainrings - 450g (573g with BB)
Shifters - Tuned Campy Record 10 Speed - 305g (without hoods) - Awaiting BTP Hoods (20g claimed)
FD - Tuned Campy SR (2011) - 70g
RD - Tuned Campy SR (2011) - 146g
Brakes - Tuned TRP R950's - 227g (Without pads)
Cassette - Black Ceradure 10 Speed 12-25 - 88g (with locking!) - Lightest in the world, apparently .
Chain - KMC X10SL DLC All Black - 252g (Full length)

Would love to hear your comments, feedback, questions, advice etc..............

Mmm, carbon.

What tuning did you do? Let us know how the cassette shifts and lasts.

Wowza

What tuning did you do?

Mainly removed the clear coat and upgraded bolts, jockey wheels and easy stuff like that - will post each individual component and details shortly.

Tremendous work, I love it. More pics of the build as soon as possible please.

Like the look.

Confused by the SR stuff. It's 11 speed and not compatible with those shifters, & chain. Sorry. Suggest you look for 10-speed front and rear derailleurs and do your magic on them instead.

Or a cheaper alternative would be to get an 11-spd KMC chain, and play with the RD cable attachment, as it's only a small difference in ratios.

This set-up should be compatible - I have lots of mates riding similar set-ups (mix & matching 10 & 11 Sp) with no issues and there are loads of threads out there confirming this set-up will work:

viewtopic.php?f=3&t=90420" onclick="window.open(this.href);return false;

Most importantly, i have matched the shifters, cassette, chain and chainrings. The SR 11Sp derailleur cages can both accommodate a 10 Sp chain and are therefore governed by the 10 Sp shifters. In addition though just to make sure, i installed the 10 Sp 11T (and wider) Fibre-lyte Jockey wheels in the SR RD widening the cage and the SR FD cage was also widened slightly in the 2011 update to prevent chain rub thus improving the use of a 10 Sp chain, hence why i went with the 2011 SR FD and not 2010.

However, i do need to test out the Ceradure Cassette as not much feedback out there on these, but that should work as it is 10 Sp just like any other 10 Sp cassette working with SR RD.

I know loads of people will want to confirm/debate this but id rather not let this thread get into a discussion over compatibility as they get very long-winded and i have already confirmed with multiple other sources that this set-up will work.

Stronglight Helion (Time Branded) Carbon/Ti Crankset.

Original weight 537g (640g with BB)

Saved 66g with the fibre-lytes (50/38T) over stock (53/39T) chainrings (119g to 53g)
Saved 16g with a lighter BB spindle sleeve (22g to 6g)
Saved 12g by changing the stock crank bolt to Ti (16g to 4g)
Saved 2g in lighter chainring bolts (10g to 8g)
Saved 7g by removing clear coat (387g to 380g)

New weight 450g (537g with BB) - Total weight saved 103g


Half way through sanding


Sanding complete


Sanded Fibre-Lytes installed (without 4g Ti Crank Bolt) taking it to 450g

[Juggler]

Saved 66g with the fibre-lytes (50/38T) over stock (53/39T) chainrings (119g to 53g)

53 grams in total for both 50T and 38T? Sounds pretty light...

I know.....Worth every penny

Funny thing is you can get these in the same size rings but even lighter from Steve at Fibre-Lyte in their ultralight versions - these are their lightweight versions - they also have a stiffer version and an aero version too.

What do you do to get that finish? Do you just sand? If so, may I ask what you sanded with?

[Juggler]

That is CRAZY light...

I use the Stronglight CT2 on my road bike... and since I use the small ring from time to time (and use Di2) it might not be the best idea.

But it is definitely tempting with that weight...

How much did you bleed for those?

[Juggler]

PS. Love the look of the "gruppo"... stealth is awesome

[lo5707]

The crankset and chainrings are sanded by hand back to raw carbon using 200 grade sandpaper and finished with 600 then 1500 dry then wet.

The brakes are lightly sanded to matt finish using 1500 dry and wet.

The dérailleurs and shifter lever clear coat was removed with razor blade and simply chipped away which left a completely smooth finish too.

Fibre-Lyte chainrings are in the region of £80-90/€97-110/$130-145
