Purchasing Decisions

Goodie but oldie, should I get it used or brand new?

As I gather parts for my frame build up I continually have to address the question: should I buy used or should I buy new? Unless you have an unlimited budget I’m sure you’ve probably asked yourself the same question.

Much of this answer will be determined by how much your build budget will allow and what level, or weight, you’re hoping to achieve. In my situation the bike I’m building up is a full suspension 29er and my budget is “really small” while also shooting for durable, weight conscious (not weight weenie) bike.

Sounds like an oxymoron right? Finding parts that are durable and weight conscious but are light on the budget are typically not compatible features in bike parts. But, I think it can be done or maybe I just hope it can be done. To help along this process, I had to consider buying used equipment. But what should I buy used and what should I buy new?


Durable and weight conscious, too bad it’s not cheap

For some advice on this, I turned to a friend who enjoys shopping for bike parts and asked for his thoughts. His rule for his bikes, of which he has many, is that drivetrain stuff like cranks/cassette/chain should be purchased new as to avoid weird wear patterns from prior usage. Control stuff like handlebars, stems, saddle, seatpost, can be bought used as long as they’re not too used.

Practical advice. Another piece of advice that I’ve learned is to be patient. A major factor I have on my side is time. I am not in a rush to build this bike up because I have access to other bikes. This gives me the option to wait for great deals to come along or to search the classifieds.


Score! Time permitted me to wait and I was able to nab this for cheap!

Having time allowed me to score a great deal on some gently used Easton Monkey Lite XC bars. Initially I had set my sites on any brand’s high end aluminum handlebars as this fit my “durable and weight conscious but also wallet friendly” budget. I figured that a manufacturer’s top of the line aluminum bars would be light weight and durable but not as expensive as carbon fiber bars. However, since I had time I was also keeping my eyes peeled on the used market which turned out pretty well, if I say so myself.

In the case of these bars I was able to achieve all of the parameters previously outlined for the build. Will this happen for all the bike parts? Probably not. But a man can hope, right?

Guest Review: Crank Brothers Cobalt Crankset

Posted by Jeremy Yang On June - 5 - 2008

This review is from one of our riding partners, Tim “Scissor Hands” Shears. Scissor Hands has an inquiring mind matched to a good wit. His thoughts on Crank Brother’s Cobalt cranks and his experience with Crank Brothers are helpful for those considering a new set of nice cranks for their rig.

I know what you’re thinking: a crank set review, what is there to review? Well, let me tell you there is definitely something to talk about here. Some time ago I scored a sweet deal on a new Crank Brothers Cobalt Chromoly crankset on Ebay. It was destined for a 29er build project I was planning. Isolating this review on the crankset only, without considering the bike as a whole, was a bit of a challenge but after many sleepless nights and a whole lot of caffeine I came up with a few thoughts that I’d like to share.

First of all I am a xc rider, amateur racer (two races under my belt now!) and die hard weekend warrior. I weigh about 170 geared up and stand about 5’10?. I always try to shift at the most opportune time by always trying to keep my eyes up and preparing ahead of time for hills and descents or whatever is coming up on the trail. In my experience this is the smoothest way to ride not to mention the easiest on the drivetrain. Needless to say I always tried to ride my rigs as efficiently as possible without any purposeful abuse.

Out of the box, you notice right away that this is no ordinary crankset. It is gorgeous and well thought out. A lot of planning went into the design and appearance of these parts. Maybe it’s due to the design, but I find that my heels never seem to rub on the arms of this crankset. I know you’ve seen those used cranks on Ebay with all the scrapes and scratches that seriously diminish that appearance. On the Cobalt, my feet seem to ride pretty parallel so no scratches for me. The BB is so nicely designed that I wouldn’t mind putting it on the wall, throw a frame around and pointing it out as cousin “BB?. Why don’t we have transparent BB shells? Someone seriously has to invent this.

So the installation was pretty straightforward, make sure everything is clean, greased and torqued to the proper specs. This setup is an ISIS only design. I had previously read some pretty negative comments about ISIS drive setups but decided to take my chance anyway. Crank Brothers has a ridiculous 5 year warranty on the Crankset and BB. I actually got to take advantage of this offer as for some reason I could never get the crank bolts to stay tight. It got to the point that not even blue Loctite could keep the non-drive side to stay torqued. One e-mail to Crank Brothers and off went my set up via USPS. A few days later I had a brand new setup on my porch with a surprising upgrade, a titanium BB. From the quick response and the upgrade, I can confidently say that Cranks Brothers does know how to take care of its customers.


Installed on the On-One

Riding these cranks presented no problems with stiffness or flex. I’m not a big guy so maybe those with a little more girth would beg to differ. I’ve read that Crank Brothers came up with the idea for these cranks by playing with a shoe box and what they noticed about the stiffness of the overall structure dramatically increasing when the lid was on compared to when it was off; don’t quote me on this but either way I had no issues in this department.

One thing I noticed was that my feet, while riding, were now a little closer together than when I rode my other bike set up with a Race Face Evolve Crankset. Apparently this is known as the Q-Factor. Where the “Q? came from I don’t know, but what I found out was that I actually preferred my feet in this new found position. It’s probably a personal thing that everyone has to discover for themselves, but I found it to be more comfortable on longer rides.

Overall this Crankset and BB were a great addition to my build. After some initial adjustments and a quick e-mail to Crank Brothers I am a happy camper and feel as though I made the right decision with my hard earned money. Quality shifting was always present (with proper front derailleur adjustment of course) and after the BB bearings were broken in this crankset would spin very freely. I paired this Crankset with an xt cassette and a KMC 10 speed chain (the weight weenie in me made me do it) and it never missed a beat. I never got around to actually weighing the parts on a proper scale to see if they weigh as much as advertised but the good ol’ hand hold test revealed that they were definitely light enough for me. My build ended up being 22.3lbs which made me very happy.

If you want a great crankset backed by a company with excellent customer service and a warranty no one else is offering, than this is the one for you.
