My XTC composite 29er (2013). Carbon frame, handlebars, stem, seat post, Stans Arch EX / Hope hoops wheel set, Hope M4 front and rear, SRAM X0 running gear, SRAM XX Cassette, SRAM PC1091R Chain, full titanium bolt set, DMR Vault Pedals, Continental speed king tyres, ESI Chunky grips, FIZIK Alante VS saddle.

 

Your tires are tanks. You can't go weight weenie until you are ready to ride lighter tires. I personally love Rocket Rons. Light weight and great grip. Your cranks and brakes need to go, as do your wheels. If you aren't willing to make those changes, you should just enjoy the bike, as is.

 

Pull the cranks and look around the bottom bracket. Sounds just like my issue that resulted in cracked chain stay near their flimsy aluminum chain guard. Giant puts inserts in their bottom brackets. I believe mine cracked at one of these inserts or where the BB connects to the rear triangle.

 

My XTC composite 0 1x10 set up.

 

It looks like Giant is discontinuing the XTC Composite and all other Composite bikes starting 2015. None are shown on their website and the Toray 600 that "Composite" frames were made from is no longer available.

 

what are you talking about discontinued ?

I have a new 2015 Defy composite coming

and have been riding a 2015 XTC Advanced Composite for two weeks now

wtf are you smoking ?

my new 2015 is a 27.5 XTC composite

and looky here a brand new composite 29'er XTC
XTC Advanced 29er 1 (2015) | Giant Bicycles | United States

Giant will -never- stop making composites, advanced, or advanced SL, these bikes rule and Giant is not stupid

 

Hmmm... I only see Defy Advanced, Defy Advanced Pro, and Defy Advanced SL for carbon framed Defy on Giant's website. I don't see a Defy Comp model like in prior years - of which I am an owner.

The Comp is a lower level carbon fiber which it does not look like Giant is producing anymore, nor is the manufacturer of the composite material for that matter.

 

Giant has two types of carbon bike frames for all models (except the purely alum ones) in 2015. Advanced SL or Advanced. Do you mean they had a third one of lower grade and that is discontinued ?

 

^^ Yeah I get it now, thanks

yeah Giant dumped it and now does it all in house
[regular flavor] or [$$$ flavor] with nanofiber

even the grade chart of fiber types is missing the bottom level

------------------------------------
this is the 2013 Defy description

"Giant Composite Technology"

the Fork for it is called 'Advanced Composite',

so it was a mongrel of the old school and new school on the fork....and the type of fiber they are keeping for 2015 and forward

I'll say one thing about my new XTC advanced carbon...it rides SWEET everywhere and especially on climbs. So much better than other bikes I have owned which cost double or triple (1998-2000 vintage Litespeed Tellico and Yeti ARC, both loaded to the gills with what was then the top line XTR and Mavics)

Giant does know wtf to do with carbon and making a hardtail out of it for sure

 

but wait !

What is this Comax stuff ? is this the old tech ? seems 2015 bikes use it

the sport line of bikes medium-low price

CoMax Composite Tech | Technology - Giant Bicycles | United States

FastRoad CoMax 1 (2015) | Giant Bicycles | United States

 

I had to dig for it. the site is full of links you can't easily find, but google can find them

 

Interesting that they now show "CoMax Composite Tech" on that same website. Maybe their replacement for the base model Composite?

 

They only use CoMax on very few road bikes like the Fastroad CoMax and cyclocross bikes.
It looks like CoMax frames have fiberglass inner layers and a cf shell. I'm sure Giant knows more about this than me but since cf is stiffer and more brittle than fiberglass, I would think it would be better to have the cf on the inside. CF on the outside would be stiffer but it will be taking all the load.
With cf on the inside, the fiberglass would take the initial load and after some flexing the stiffer cf would then reduce further flexing. CF on the outside would look better, though.
I see no CoMax mt bikes.
On Giants website I think they imply that they make their cf but since they use Toray part numbers for their cf, I think they don't make their own. Giants cf technology is their ability to design and build frames with Toray cf.

 

Does anybody know the weight of XTC Composite 29er 1 (2014)? Thanks.

 

Email a shop that has one, pretty sure it's 11.5kg medium last I checked.

Is the XTC Comp 29 1 worth getting over a Scott Scale 930, Spesh Stumpy or Trek Superfly 9.6? I'm a bit anxious about that 71.5 HA.

 

XTC composite with upgraded wheels and 40t OneUp gear 1x10

I have posted my bike before and I upgraded to Roval Control carbon and 40t UpOne bailout gear.

Ha! We ride in the same area. That bailout gear comes in handy in the those East Bay hills

 

Can wider bars cure the twitchiness?

 

Just picked up my '14 XTC Composite 29er 2 last sunday! Coming from a '09 XTC 1. I've only ridden around the house this past week but so far I love everything about this new bike especially the bigger wheels. Hopefully going for a good ride on some "real" trails this sunday.

 

Has anyone replaced the OD2 headset from their composite frame and replaced it with a 'normal' tapered version. (i think only the top cup needs to come out)

I am considering future proofing my 2013 XTC but am worried that the cups will be glued in and wont be able to be removed without damaging the frame.

 

Just weighed my 2014 xtc composite 29er 2 in case anyone is interested, it came in at 11.5kg. It is 1x10 with 32 tooth blackspire nw chainring, elite plastic bottle cage and empty water bottle, stock everything else.

 

Funny you say that. The shop that did the headset on my 14 trance had to use a surprising amount of force to get the stock cups out.

 

Found this under the Christmas tree

Going on a year but still digging' it.
Switched out the Rovals for P-XCR0's
Nice and light @ 21.5lbs as pictured.

 

9.5kg/21lbs

 

Any idea what a good condition 2013 xtc 29er 2 go for used? Would it be a good first bike?

I'm buying my first bike and debating over used or new. Right now even the used xtc is over my price range but am interested what would be a good price for this bike? I think it was 1400-1500 new in 2013

 

You can look up values of used bikes here:

I bought an XTC Advanced 29er 1 last week and currently have about 75-80 trail miles so-far. Love the bike. Here's a link to a thread I started where I shared my initial thoughts. I'm going to keep updating the thread with my impressions as I get more time in the saddle on the XTC.

Failed freehub on my less than 1 month old Giant XTC Composite 29er 1.

Replaced under warranty.

We'll see how long this replacement lasts!

Never had a freehub fail on my last bike, an entry-level Specialized Hardrock.
