Hello all,

Well Im new to the ibis section of these forums but it seems I might be soon taking a ibis into the collection. Im looking at two options, bearing in mind Im looking at building the ultimate XC bike

So my dilemma is do I go for a Mojo or a tranny? I admit im a bit of a weight weenie so either way im looking to build a uber light bike, (below 23 pounds if a mojo, below 21 pounds if a tranny).

Either build would consist of similar components, Sram X0, truvativ Noir, DT Swiss carbon fork/ Rockshox sid team, and possibly a Mavic wheelset.

So Im wondering what would you ibis lovers buy and why?

Thanks Liam

just my opinion, but i would go with full suspension for ultimate XC.

i consider ultimate XC to be an all day "epic" ride or endurance race. if this is how you envision any of your rides, wouldn't you too want full suspension?

if you only plan on doing shorter 1-3 hr outings, maybe a hard tail is more suitable.

don't forget, the full suspension will do just fine on the shorter rides but the hard tail might not be so comfortable on extended rides.

An SL with the right kind of finishing kit would be up your street. I personally would always have a hard tail, trail bike and dh beast in the quiver so I guess its up to you what slot you are trying to fill. The Tranny looks lovely but the Mojo is awesome

another seat-of-the-pants opinion. i went from a 25lb hard tail to my 25lb mojo and don't really feel like i am giving up anything in efficiency. the transition was seamless. maybe the geometries are close....i never really checked.

on mild XC trails, i do not feel like the 5+ inches of travel is too much. it feels fine. i am very happy with the bike. however, i will definitely keep my hard tail! :thumbsup:

From your public profile you do not have that much experience and still you want to build the ULTIMATE XC bike???? If you want more than purely subjective answers which won't help you that much you need to provide us with a little more information.

The ultimate XC bike for a seven day mountain crossing race, like the once in the Alps, would be an 8.5 kg HT; if you have experience and ambition.
But if you just want to go for a relaxed cruise through the woods, playing around on different technical trails the ultimate XC bike would be something totally different.

And keep in mind that there are other factors than weight: reliability, maintenance and costs are some of them.

Good luck

Go for the MojoSL! You can ride it all day and still want more. If you are racing on Trans-alps, ok HT is fine because the race is all road anyway, but if you do something like the BC bikerace, you will regret not haveng rear suspension. (At least your ass will regret it! lol) The SL with the lockout on the DT Swiss is a HT anyway! So you get best of both worlds with theSL. Mine weighs in at 22 lbs. A SS Tranny would be a sweet 18 lb bike.
Hey MX! that pic sure beats a pressure washer anyday!

thanks for the replies guys, when i say ultimate XC bike its not like im going to trek through india or anything like that. Im looking for the ultimate bike to use for local club racing, 8hr's 24hr's ect ect you get the idea. my main concern was about it climbing (mojo) and it been slugish but it seems from everything ive read it dosent have that problem.

i would do the FS mojo then. i am not sure why sven likes HT for long events. it seems backwards to me. i guess it is nice because it would be a little lighter

even experienced pros at the leadville 100 or whatever with lance had FS bikes. i think many in that race had FS.

i did a 24 hr and a 12 hr and have a team 24 hr in february. i really appreciated the FS on these. like i hinted above, it seems to climb as well as my HT or better. i do not have lock out on mine. i wouldn't worry about climbing.

I did not say that I like HTs on long events. I just wanted to point out that Trans Alps and most XC world Cups are won on HTs. I myself would not want to put my ass through so much pain. You really need to know what you want to do with your bike. For 2009 there are FSs out there that are almost as light as the HTs and I am sure more and more World Cup riders are going to use those. Just think about Christoph Sauser on his S-Works Epic.

The ultimate XC bike. This is going to be something that is purely subjective to the user. But I can give you my imput based on 15 years of racing XC and endurance events. From local events to the Leadville 100 to a 3rd place finish at the 24-hour global championships.
First off... you mentioned similar components for both builds. What you listed sounds somewhat acceptable for a hardtail build, but the I would argue that the SID is too little fork for the Mojo. At 100mm I think you might find it a little unbalanced for the 5.5 inches in the rear, plus it may steepen steering beyond a comfortable level- for you.
If weight is your ultimate concern, go for the Tranny, or even a lightweight carbon option from another manufacturer. Period. The Tranny will always be lighter than the mojo. This doesn't always transfer into being faster.
Let me repeat that:
Lightweight doesn't always mean faster. It definitely helps, but trumping performance with lightweight typically results in an uncomfortable bike.
So the real question is where are you planning on deploying this ultimate XC machine. The Ultimate XC Machine for singletracks of places like Wisconsin (go badgers) or Texas might be a singlespeed 29er. If you are planning on racing XC, typically XC courses are relatvely smooth, non-technical affairs and your uber-light build and your big ring might be all you need. In such cases, 5.5 inches of suspension is probably overkill. Assuming all you are doing is racing.
I consider myself an XC/All mountain rider. I need a bike that is lightweight, strong, efficient, easy to control, and comfortable. For where I live the Mojo fits that build to a tee. You mentioned climbing. Here, I feel that my Mojo is a superior climber to any hardtail I have ever ridden, but I ride a lot of techy, loose climbs. If you're in pure fireroad country.. this might not be for you. But I think you will find that the notion that full suspension bikes are poor climbers is a severely antiquated one, especially as applied to the Mojo.
I have raced my Mojo XC. I have done all-days epics with 10,000ft of vertical up and down. I have employed it in multi-day shuttle runs. I like my bike in any terrain I feel comfortable riding, and I think that range has increased since I got my mojo.
I would like to advise you to get a mojo. I think that in terms of all-around performance, comfort, and light weight there is no better bike out there. If you really enjoy riding, if it is something that you love, than you will love the mojo. If you love competition, love racing in a pure form, then you might prefer a HT.
So... unless you're winning races for a living. Unless your babies will go hungry and without shoes unless you stand tall on that podium, you will probably have more fun on a mojo.
Just be honest with yourself about where and what you like to ride and your decision should be easy.

Definitely A Mojo!

I would definitely get the Mojo. The SL is about 140 grams lighter than an equally fitted standard Mojo, but the standard with a glossy clear coat looks much better.

Here's the build I put together for mine:

Frame: Ibis Mojo Nude Carbon w/DT Swiss Carbon Rear Shock
Fork: DT Swiss EXC 150 RTL 15mm (2009)
Front: Brake Magura Marta SL (2009) Red | 180.00
Rear: Brake Magura Marta SL (2009) Red | 160.00
Shifter: Shimano XTR Pods SL-M970
Crank: FSA K-Force Light Carbon (2009) 175.00
Bottom Bracket: FSA MegoExo Ceramic (2009)
Front Derailleur: Shimano XTR M971 Bottom Swing
Cassette Shimano: XTR M770 Titanium
Rear Derailleur: Shimano XTR M972 Shadow
Chain Shimano: XTR 7701
Wheelset: Industry 9 - w/DT Swiss XRC 330 Disc Carbon Rim Red Hubs Red Spokes
Front Tire: Kenda Nevagal DTC | Black | Kevlar
Rear Tire: Kenda Nevagal DTC | Black | Kevlar
Headset: Cane Creek IS-8 Carbon
Stem: Ritchey WCS Carbon Matrix Stem
Handlebar: Ritchey WCS Carbon Rizer
Grip Oury: Soft Grip | Black 140.00g
Seatpost: Ritchey WCS Carbon
Saddle: Selle San Marco Carbon

I wouldn't recommend either of these frames to you. The best basis for your "Ultimate XC" bike would be a sub 4.5lb suspension frame designed for a 4" fork. Epic, Trek Top Fuel, Giant Anthem, something like that. I'd take an Epic for pure XC racing on typical courses. You can find lighter hardtails than the Tranny (Scott Scale) and the Mojo is a trail bike designed for a 5-6" fork. I just got a Mojo SL that will be used for Cat 1 XC racing but will mostly be used for epic rides on rough trails.
