KHS SixFifty 606 has arrived!

Interbike 2009 Mountain Biking Products

Last week  took possession of the spankin’ brand new KHS SixFifty 606.  We have been featuring this bike prior to Interbike 2009.  For those that are not familiar with this bike, it sports the 650B tire size, a *new size that places itself in between the established 26” and the revolutionary 29er. (*new in the current MTB world; but the 650B has been around for quite some time.)

I had my first ride on the SixFifty 606 this past Thursday.  I picked up the bike from David “Sho-Gun” Sanderson.  The bike is absolutely beautiful… much better looking than I had remembered it from Interbike 09. I guess with the thousands of bikes I saw at the show, I had forgotten the finer details of the SixFifty 606… for one the hydro-formed top tube with a unique shape… see below.

The ride on Thursday wasn’t what I had planned for the first ride of this bike.  For one, it was a night ride; secondly with rain from the previous day, some sections of the Loop were too muddy which diverted from the normal route; the Loop typically holds up well after rain.  All in all there were too many distractions for my first ride on the SixFifty 606.

This Sunday, I took the SixFifty 606 up to one of my local training grounds – Coal Canyon.  I started the ride from my house in Corona and rode all the way to the top, which is commonly called Mini-Moab.   I was joined by my friend Val.  On the way up, we traversed through mainly fireroad and on occasion sandy sections.  From time to time there were corners with small baby heads.   The climbed to the top went exceptionally well.  The hardtailed SixFifty 606 climbed like a billy goat.  Crossing the sandy sections with the semi big tires, the bike motored through it where I had struggled through in the past with my 26” bikes.  

Reaching the top at 2300ft, we took a short break at Mini-Moab.  The long ride down Coal Canyon is always a treat as we’ll hit sections at 40+ mph (per Garmin 305).  The SixFifty 606 felt natural on the descent.  It was nimble and handled great on the steep sections.  Coming through the corners with baby heads, on the few that I couldn’t avoid, the SixFifty 606 rolled over them with control.   On some of the wider turns, I tried taking a sharper turn through them however I had a difficult time.  No biggie, this was my first real ride on the SixFifty 606.  As soon as I get acclimated to the bike the handling will be much better.   

Notes from the first two rides:  climbed great – on & off the saddle; nimble for a semi big tire, descended well.   I also felt taller, but obviously I have bigger tires.

I’ll be riding this bike through various trails in OC as well as a few races.  Stay tuned as I put miles on the SixFifty 606 and provide an in-depth feedback.

  1. I see you have CB’s on it but if you weren’t hows the toe clearance on that? Similar to a 26? Can you tell the ride difference between the 26 and the 650?

  2. DT – not quite sure what you are referring to w/toe clearance. can you elaborate?

    As far as the difference, just the few that I mentioned above. It does “feel” taller but the bike handles great! feels like a regular 26″ More to come…

    Pris – Thanks. We need to take you guys up there if you dont mind the long grind up.

  3. Joe,

    I think what DT meant would be Toe Overlap. So that would mean if your right foot was on the 3 o’clock position, and you were turning the handle bars, doe the front wheel clip your toes?

    DT. I had a chance to ride the 650 and much like Joe said, it feels taller than a 26er but not too much like a 29er. It also rode smoother than a 26er.

  4. Thanks RL. I shoulda said toe overlap…

    I still ride with flat pedals so that is always a concern for me. On my MC29 I still buzz my shoe every now and then…
