Hi
I sold my 26er by parts and now starting to build my first 29er.
I do not even know if I´m allowed to start this topic here, because the frame itself weights 1433g.
It´s ca 300g heavier than most brand frames. But complete bike should be sub 9,5kg.
Frame could have been lighter, but I wanted custom paintob and this added ca 150g.
Some parts, like brakes, crankset, grips and rotor come from my old bike.
This bike will be used mainly on XC marathons.

nice!

few things

- I would consider different components: esi grips, lighter stem and handlebar (KCNC arrow stem and MT zoom bar) and maybe a ligther saddle.
- I would not use that chainstay guard. Just wrap some old road bar tape, lighter!

Looking for your build!

Thanks for your input!

- ESI is good idea.
- First I´m going to buy cheaper 17 degree stem, to be sure I can get good riding position and if it suits then why not KCNC.
- I like the look of 3T Exsero. Weight and price is also competitive.
- I have this saddle, thats why I listed it, but I´m also considering full carbon from ebay (Touple).
- Like your idea of old bar tape. Scott guard do not fit very well will this frame chainstay bend.

What length stem are we talking about? I had a KCNC arrow stem in -17 and it weighed 145g in 110mm length (ie not any less than the one the OP is considering).

yeh, buy light KCNC stem, shave 20 g and get a sausage instead of stem. also tundra is very good decision for long marathon rides. a light saddle with discussable comfort could be a sliver in your ass in long marathons. saved 50 g on saddle won't console you after 50-60km when there are left 20-30 km or even more. we are amateurs and the first thing in riding is pleasure.

despite this I don't understand the choice of the expander instead of good old nut in the non-carbon steerer. I saw lot of riders who are bogging their mind to tight the stem and steerer properly on their mtb bike.

after all I like this project because there are some things where performance in some crucial moments is not sacrificed for weight.

but this is weight-weenie, hence the light stuff comment. Try a KCNC stem for yourself before judging. I have had several, never noticed ''flex''. Flex is overrated.

Thanks for your comments.
If the Tune expander is useless, I won´t buy it. Another options are Carbon Ti X-Plug or good old nut.

A good option for the stem would be a Zipp Service Course SL in -17, not sure if it is available in 80mm though. Sounds like you'll have a nice build!

yes, I've tried: KCNC stem, flat bar, X-7 brakes and other small stuff. cheap and light stuff usually doesn't have good stiffness, durability and performance. such eastern manufacturers as KCNC, Aerozine or others are the examples.

Got fork and chainring today and they both look awesome.
SID RCT3, 1540g with cut steerer.

Wolf 34T, 61g. It came with washers, so I can use my existing Shimano bolts and these are great.

I have also edited my first post.

I tried those Ashima Ai2 rotors for one ride - the performance was awful, not to mention the hand fatigue.

I bought only 1 rotor for rear and if it fails, I have Shimano rotor for replacement.
