Ip256sl building in progress

[Sjon7283]

Hello,

I'm planning my ip256sl build and just made the order. I have to wait for 25 day, because of the popularity of the frame. I've had mailcontact with Bert from xmiplay and i must say, it't great so far.

Frame: ip256sl, 17,5", mat black UD
Fork:    Rock shox Reba, black, poplock (maybe upgrade later on)
Groupset: full sram xx1 (trigger shift)
Seatpost: sp7, xmiplay, 400mm
Brakes: sram xx, hs1 rotors 160/160
Handlebar and stem: xmiplay, 620mm/90mm
Saddle: not sure yet.
Grips: esi
Tires: RaRa

I'm going to use the bike for xc competition in the Netherlands. I'm not realy sure about the rims yet. I was planning to buy the ZTR crest rims, but i'm hearing some good things about the carbon rims from China. Does some of you have some good reviews of some of those?

Are you sure about the handlebar ? I think 62 cm is to short ( I know you're coming from a 26er). My previous 29er had 71 cm, now I'm riding 68 cm. And I had to get used to it

Got my wheelset from xmiplay and they are really great. Light, 1540 gr, Novatec hubs (= easy to maintain). I like them.

I now have a 58cm handlebar on my 26er. I find it difficult to choose the right size on the 29er. Perhaps 620 is to short, but i ride a lot of narrow singletracks and i'm affraid that with a wide handlebar, i'm getting problems with some trees...

The carbon rims do have a great weight, simmular to the ZTR's. Do you notice the benefits of the wider 30mm rims?

You may ask to Nancy at light-bicycle.com too.
She is very competent and fast to reply.
In addition they may have more hubs/spoke types available.

After a very rough and rocky ride, my rear wheel(30mm hookless on a 256 19" frame) went out of trueness for about 3-4mm.
I remember the moment of a big hit, by the noise it made, I even thought the rim was broken.
But may be as advertised, hookless rims resist better to abuses.

I contacted her.
She told me it can happen for a new set of wheels, and asked if I had the adequate tools.

Got a spoke wrench and tightened 3-4 spokes, and it is now true again.
I'm very happy of these carbon rims.

With 30mm it seems you can put a lower pressure.
However I use 1.8-2 bar( I'm 72Kg).

For the bar. I was coming from a 26" too, and didn't want those wide bars.
So I took a 66cm bar, that fits my shoulder width.
And can still corner as near to the trees as before.

[MTB2223]

It's easier to shorten the handlebar than make it longer 

Yes, I notice some more grip with the 30mm rims. But, I'm not really sure, I also notice some more resistance when riding in the mud, but again, I'm not really sure yet. I'm finding the right pressure. I'm now riding the same pressure as carbonazza, 1.8-2 bar (I'm 82 kg).

I'd recommend the 30mm iPlay carbon wheels, I have the bead hook version, the hookless came out after I purchased.  The rims have been very good and have stayed true after 5 months of riding.

As for the bars, I run 680mm and we have some narrow single track around here.  After a few rides I now prefer wider bars.

[Sjon7283]

I think i wil order the size 680 handlebars, thanks for the suggestions!

[Sjon7283]

Carbonazza: witch set dit buy at light-bicylcles and is the configuration?  (Hubs, thru axle or qr)

Can you tel me the weight of te set? I was first planning to buy the ztr crest, sort of a save choice, but now i'm seriously considdering a carbon Wheelset.

Thanks again!

[Carbon_Dude]

I think i wil order the size 680 handlebars, thanks for the suggestions!

For me 680mm is a good size, I could go up to 700mm but that about my limit.  I suppose you can go even wider and later cut them down if they seem too wide.

[carbonazza]

Sjon7283, I took hookless rims.
The external width is 30mm, there are thinner and lighter rims for XC, I think, but I preferred them more robust.

The front wheel has a 123 project hub(for a Lefty fork) and is 680g.
The rear wheel has a Hope Pro V2 Evo(for an XX1 cassette) and is 856g.
Laced with their Pillar aero spoke PSR X-TRA 1420, 32 per wheel.

They say tubeless ready, so it means you need to put a tape(Stan or other) over the spoke holes.
If you want to go tubeless with them. What I did without any problem.

[Vipassana]

I have the weights of the 30mm Iplay hookless in my build thread if you want to go take a look. Very comparative and impressive weight . the entire industry seems to be moving to wider rooms for XC use but both Iplay and Lightbike have lighter weight narrower runs as well if you desire. 

For the handle bars, I would definitely go with wider bars and cut then only after you ride it for a while. I find I can't stand 29ers with traditional 26er bar width. They are unmanageable.

[Sjon7283]

My rock shox Reba has a 9mmQR and at the rear i have the 12x142 axle. When i order the wheelset, i want the wheels to be future proof. Is it possible to concert thru axle (novatec) hubs into qr 9mm compatible wheels? When i upgrade my fork in the future i can simply switch to the thru axle.

On the light bicycle site, there's a difference in novatec hubs. Running it with thru axle means a whole different type of hub according to their site. (Less lightweight)On the other hand the xmiplay site revers to the same novatec hub in both the qr version as the thru axle version. Does anyone know whats the best choice?

[Sussed.]

Had a similar problem with my original wheel order and a change of fork !


Double check this but I think the Novatec D771/D772 will cope with 9 and 12. While the D991/992 is a 4 in 1 which will accommodate all 4 standards as all 4 types of end caps are included.

(Have a look at novatecusa.net for all the D type hubs)

Today i got my hands on a new wheelset. Sorry guys no chinese carbon:

ZTR crest 29" no tubes, RaRa 2.25 with DT SWISS 240s hubs, dt swiss competition spokes and nipples. ( black)

The reason why i choose for this set is that i had the opportunity to get it at a rear good price. Maybe upgrading the set with a couple of carbon rims in the future, but for now, these are my best new friends..

Set need to be converted to xx1 freehub and 142x12 TA at the rear. Does somebody have experience with converting a hub into 142x12?

[MTB2223]

I found this via google:
- Axle conversion kits http://www.wheelbuilder.com/dt-swiss-axle-conversion-kits.html
- freehub conversion kit http://www.wheelbuilder.com/dt-swiss-mtb-rotor-kits-to-convert-to-sram-11-speed.html

Now you have the partnumbers, so it's easier to find prices.
