Santa Cruz Superlight 29 Introduction
Posted by FatBob on May 6, 2012
I was very happy to see Santa Cruz Bikes launch the Superlight 29 – a 4” travel, single pivot, full suspension bike. This is a bike that fills a solid need in current 29er market; a value driven, high performance frame with the best technology. I realize that the above statement about filling a “need” seems like a bold statement from 29erOnline. After all, it is a 4 “ travel 29er. It’s not like we have never seen one of these before.
I have seen single pivot 29ers come and go over the last few years. What makes the Santa Cruz Superlight 29 special is that it is a competitively priced bike with enough versatility and technology that you won’t feel limited as you grow as a rider and want more from a bike. Nor does it have too many dedicated “standards“ that would make upgrading a pain. For example, tapered steer tube compatibility. While making for a stiffer frame and also fork interface, you are not forced to buy a tapered steer tube if you have existing parts you want to swap over. All it takes is a reducer crown race and a standard 1 ⅛ steer tube will work fine.The bottom bracket is a threaded aluminium 73mm shell. This is the easiest bottom bracket to find compatible units for and fairly common, inexpensive tools are all you need for installation. Again, if you are transferring parts, chances are you will be able to do so successfully. The Superlight uses a common size 30.9 seat tube that allows you to pick whatever dropper post you decide to use. In addition, it provides cable guides for dropper post use. So, as these couple of examples briefly show, upgrading this frame should be fairly simple because it comes with the right technology to boost performance. Where it is least needed, it skips it, and, therefore, comes in an affordable package.

The geometry was derived from the Santa Cruz TallBoy that many people speak highly of. We can’t speak to the bike from direct experience; Santa Cruz won’t send us a test bike because they think we are too small. We’re growing fast, so maybe soon they will reconsider. Not one to hold a grudge, we bought the Superlight. Like the TallBoy, the Superlight uses a 71 degree head angle, combined with a 73 degree seat tube angle. The 17.5” chainstays are the same length as are the superlight 29 and TallBoy stop tubes. The top tube remark is mostly correct. The measurement is the same from the medium size to the XL size. The Superlight comes in a size small with a 22.5 top tube where the TallBoy does not come in a small size, period. The second noteworthy difference, by numbers, is the bottom bracket height. The TallBoy has a low 12.8” bottom bracket height, while the Superlight 29 has a, still low, but more friendly, 13.1” bottom bracket. I guess you can say the geometry was inspired by the TallBoy. It is not a clone.
The Superlight suspension is a very simple single pivot design. As with most things in life, the simplest things are usually the hardest to get right. This uncluttered suspension has undergone years of fine tuning to get the design to ride correctly. Single pivots are easy to maintain and fairly straightforward to set up. However, they are not without flaws. A poorly designed single pivot bike pedals terribly, with an odd floating sensation and lots of bobbing. In addition, a poorly executed single pivot tends to stiffen during braking. At the extreme end, you can get pedal feedback and shifting issues. Worst case you can get catapulted while braking. Still, when done right, they are simple, easy, low fuss systems that work great.

Santa Cruz gets it right – all for a frame price of $950 dollars. This is half the frame price of most bikes that we test. Complete bikes can be bought for $1,850 (D XC kit ) or $2,350 for the R XC kit. In the high end 29er market, those prices are very competitive for a full suspension bike. In short, the Santa Cruz Superlight 29 fills a void because it is a simple design with high tech features and it comes in at a price that makes the price of entry within the sights of many enthusiast riders. It is bikes like this that can get a rider on a 29er with minimal sacrifices and plenty of room to grow.
So what about our test of the Superlight 29? Our Superlight 29 is a size small. It has a massive amount of standover and a short top tube. We have a couple of short, women riders that are part of the 29erOnline team and the Santa Cruz fits them like a glove. We will be getting their feedback on the pros and cons of the Superlight 29 from a short rider’s perspective along with a woman’s view. In addition Jamie will fit this bike as well, so we will have an enthusiast rider’s perspective with testing experience. I will be paying attention to their comments to see if they come up with any performance negatives along with my own set up observations but I will not be riding the bike as 6’2” and small frames do not a reveiw make.
If you are unfamiliar with the long story behind the history and evolution of this model, this is a great write up by NSMB.com.
