Sette Razzo 29er-Complete Bike Now available
Overview:
The moment we started offering the Sette Razzo 29er frame requests started pouring in for a complete bike.
Sette USA heeded the call and they came back with a complete Razzo outfitted with a killer parts spec. It reads like a who’s who of the best brands in the cycling industry.
SRAM and TruVativ handle the drive train. Up front a RockShox Reba SL 29er Dual Air takes care of business when the going gets rough. And when things get too rough, Avid Elixir CR hydraulic disc brakes will bring the Razzo down to a more manageable warp factor.
29ers have now been around long enough most everyone knows the reason why they have such a rabid following. It’s because of the ability of the big 29 inch wheels to rollover just about anything, covering ground faster than a bike with 26 inch wheels.
We could go on for days about the advantages but really, if you’re reading this, we’d just be preaching to the choir. So the important thing for you to know is that the Razzo is outfitted with Shimano Deore 29er specific hubs laced to disc specific Mavic M719 rims. Mounted to those Mavic rims are a set of Kenda Small Block Eight Kevlar beaded tires in a 2.1 width that are ready to make any line the Perfect Line.
Finally, the icing on this highly polished cake is a cockpit that features Sette’s own lightweight, high performance handlebar, stem and saddle.
The Razzo complete graces the scales at an average weight of 26lbs.

Just what in the hell are “29er specific hubs”?!? That’s a marketing hyperbole pile of crap!
The rear hub is the Shimano M529

A beef’ed up hub designed for the new 11-36T cassette that newer MTB’s are sporting now, to withstand the added torque.
I still call B.S. — two more teeth on the largest cog actually generate less torque when coupled with standard chainrings, and many MTB cassettes already have an 11T small cog. If this thing is true, there’s GOT to be some other aspect…longer spokes and higher tensions, etc.
The larger the gear reduction (i.e. smaller sprocket in front and larger in rear), the greater the torque multiplication. That is simple physics. You will have less torque input at the cranks to produce more torque at the rear wheel. Does the hub need to be beefed up for this? probably not as the average human with the gear ratios supplied isn’t going to be able to produce enough overall torque through the gear reduction to damage a hub.
However, with a 29er wheel, you have a longer radius from the wheel hub to the tire contact patch which means that under braking, there is more torque input to the brake rotor, This essentially means that the brakes have to work harder to stop a larger wheel. With the kinetic energy created by a larger rider on a steep downhill some engineer must have decided that there was the possibility of the brake rotor breaking off the hub under extreme conditions and decided to beef it up and call it a ’29er’ hub.
Does this mean that if you put a regular mountain bike hub on a 29er, the brake rotors will shear off? Probably not, but when you’re selling a bike that literally anyone can buy and abuse you need to have things overbuilt because of the liability issue and the fact that you probably don’t want to end up in court when some idiot that weighs 300lbs tries to stop the bike on a 30mph descent and hits a tree.
Learn a little more about physics and what companies have to deal with when they design and sell things to the public and your opinions will probably change…or not, I really don’t care.
