Here are the specs for some of the legacy bikes, along with recommendations for anti seize and Loctite.
Mojo and Mojo SL:
Forward shock pin bolts: 4 Nm (3 ft·lbs) with blue Loctite for a steel pin and anti-seize for a titanium pin.
Rear shock bolt: 6 Nm (4.5 ft·lbs) with grease for a stainless steel bolt and anti-seize for a titanium bolt.
Main pivot shafts: 10 Nm (7 ft·lbs) with blue Loctite.
Swingarm shaft bolt: 6 Nm (4.5 ft·lbs) with blue Loctite for a steel bolt and anti-seize for a titanium bolt.
Upper link bolts: 6 Nm (4.5 ft·lbs) with blue Loctite for a steel bolt and anti-seize for a titanium bolt.
Rear brake caliper bolts: 6 Nm (4.5 ft·lbs) with blue Loctite
Both lower link bolts: 10 Nm (7 ft·lbs) with blue Loctite
All forward shock mount and pin bolts: 4 Nm (3 ft·lbs) with blue Loctite
Non-QR seat binder bolts: 5 Nm
We think that all those materials are good for construction of bikes. Ibis has made bikes out of all these materials before, and might do so again. For now, we like the results we get with carbon. Read our little treatise here. Scot Nicol, founder of Ibis, wrote a 7 part series on bicycle metallurgy for VeloNews back in the day. At the end of the series, one of his conclusions was that soon it would be carbon's day in the sun. We think that day has arrived. Read Scot's series here if you're having trouble falling asleep.
Although this is a question we probably should put in our “IAQ” (infrequently asked questions) we still get the occasional naysayer. So please go here to find out what we have to say about the durability of our bikes.
The Mojo, Mojo SL and Tranny all use the integrated standard. The Mojo HD uses a mixed tapered and the Silk and Hakkalugi both use the Campy Hiddenset Standard.
If, not, no worry. We've created a page that describes a standardized headset naming protocol that many manufacturers are adopting. You can read about it on our headsets page: http://www.ibiscycles.com/support/technical_articles/headsets/
We also like the new Cane Creek Headset Fit Finder.
We don't actually publish a maximum rider weight. We have found that rider weight has a bigger impact on wheels than it does frames. Frame failures tend to be less a matter of actual rider weight than the peak loads experienced. So riding style contributes more to frame failure than weight. Do you break a lot of frames? If you do then it's more likely something related to riding style than of frame durability.
The terms low, medium and high are relative terms referring to modulus. Modulus is a reference to stiffness, which doesn't always correlate to strength. In the case of the bike industry the terms are somewhat misused. Typically bicycle industry folk use the term "high modulus" to refer to T800 or T1000 Toray fiber, as opposed to the more commonly used (in the bike industry) T700 fiber. In real terms T700 would be considered standard modulus and T800 and T100 would be intermediate. The higher modulus materials often come with a compromise in terms of tensile strength or elongation which means that even "high modulus" frames are really a blend of T700, T800, or T1000 (which have the best overall mix of characteristics) with small amounts of the higher modulus stuff in areas where additional stiffness is required in a super light frame. However, there are no hard and fast rules here, so a company could call just about any composite material high modulus depending on what they're comparing it to.
The Silk SL and Mojo SL are blends of various fibers, but the frame is primarily T700 and T800. Until very recently, T800 was the best you could get, and still in terms of overall performance it is the best all around composite material available. In the Mojo HD we use a different brand of fiber but it's equivalent to T800 and T1000. The Hakkalügi uses T700.
The rear shock length between eyelets is 7.875" and shaft travel is 2.0". DO NOT deviate from those dimensions, catastrophic failure could result!
We make a nice, strong 1800g wheelset for certain build kits.
The front hub has 9mm, QR15 and 20 mm compatibility. Both hubs have serviceable, sealed bearings. The rim is 480g 32H 20mm bead-to-bead with stainless eyelets. The spokes are double butted (14/17G) stainless with brass nipples.
If you must know more: Joytech D881S & D882S hubs/Alex SX44 (SLX wheel) or Stan's ZTR Flow (X9 Wheel) or Stan'z ZTR Arch (XT Wheel) rims.
Some people have successfully mounted Rohloff's to their Tranny. We haven't done it. It requires some grinding on the dropout. We don't condone this, but again, some people have successfully done it. They attach to the rear disk mount with a device called the speed bone that provides its reaction arm. Again, we haven't actually mounted one, but since the forces act just like a disk brake the Tranny will be plenty strong enough to handle the Speedbone.
To switch to 140mm travel from 160mm travel on the Mojo HD, you need a set of Limbo Chips (upper shock mounts) available in the Ibis Store.
You'll also need a different rear shock (identical to the shock found on the Mojo SL-R and HDR 650b), which unlike the Limbo Chips is not available in the Ibis Store (we're not allowed to sell the shocks separately). To make it easy for you to get your hands on a shock, we've got some info here on how to get the correct one.

Fox knows our bikes well and can guide you on the shock that is appropriate for your needs.
