General FAQ

No. This website is our brochure for now, but if you have any further questions or want more info, call or email, we'd be happy to help.

We use three different factories to manufacture our carbon frames. A small producer makes the Mojo and Mojo SL frames in a factory in Shenzhen, China. They are in an area where much of today's carbon manufacturing is coming from (Kestrel, Specialized, Colnago, Scott, Cervelo, Trek, Merlin, Orbea, Felt, Ridley and a bunch more for that matter). The owner of the company has a PhD in composites and has done a lot of work for both universities and the Taiwan government. We do all the development here, the design, FEA, engineering and testing. We have over 1800 hours of CAD time into the Mojo alone.

The forged parts come from a well-known fabricator in Taiwan. They also make the cases for iPods, Macbooks and iPhones, and probably the iPad. No, we can’t help you get Apple stuff cheap.

The Mojo SL uses higher strength, higher modulus carbon, so we can use less of it, resulting in a weight savings. Additionally, the Mojo SL has carbon fiber headcups, dropouts and seat tube insert vs the aluminum found on the Mojo Carbon. The SL also comes with a complement of Titanium fasteners.

Here are the weight savings you can expect to find on the SL.

Weight savings Frame: 130g
Weight savings if you use the DT Swiss Shock: 65g
Weight savings Ti Bolts: 40g
Weight savings bolt seat binder (vs QR): 45g

Total = 215g (.47lbs)

Finally, note that painted frames are approximately 60g heavier than clear.

We STRONGLY recommend using only shocks supplied by Ibis. Even a tiny change in shock length or stroke can result in CATASTROPHIC FAILURE of the frame.

Another issue is that the suspension is designed in conjunction with the spring rates of the shock and changing the spring rate can adversely affect the performance.

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're liking 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.

You can’t powdercoat a carbon frame, as the powder needs high temperatures to activate and cure the powdercoat. So you need to wet paint the frames (like they are done in the factory). You also cannot sandblast the frames, they need to be wet sanded for repaint.

It’s a tricky process, but these guys have painted a few of our prototypes and are reasonably priced and do a nice job:

And these guys have been around forever and have an excellent rep:

We like to say Ibises. 

According to this wonderful page, it's a crowd of Ibis. There are a lot of better collective nouns out there, check out that link for some good ones.
