New 2011 race rig- Kona King Kahuna.  Did a 6-hr race on her this past weekend, felt good.  Hopefully she'll be lining up for ORAMM in July....

Waiting on the new Selle Italia SLR to come available, may dump the SRAM- 2 new cranksets this year, both had loose chainring bolts within 3 rides.

very nice man

The numbers you guys are using for crank sets are the #  of teeth on a cog?   The money I was going to use for a new bike is going towards a duc..  so I'm going to take my existing bike and mod it up..  cutting handle bars, stripping paint, removing rear brake and gearset with components.  Want to replace with single gear just don't know what size..

Yes, it's done by tooth size.  Crank arm length and wheel size will affect it though.

For my road fixed gear- 40x17 with 170mm arms.
29er mountain single- 32x18  if you have 26" wheels you'd run a 32x17 to get a similar roll out.

It also depends where you ride (climbing) and your fitness.  I can ride 10 miles just about anywhere with the 17 on my SS 29, but I keep an on 18 because I usually ride longer distances.  When in doubt I'd run a tooth higher in the back- easy to change and a lot less miserable than erring on the too tall side.

It'll be for going to work, down hill, and strength training other times.. so I don't mind having to crank out. I'm going to leave the front break on and not go fix geared thgh.. want to be able to coast down hill...  I gotta check the wheel size on her again..but might end up geting new ones anyways..

I haven't posted my bike up yet...I think...

Anyways, it's nothing special, just some cheap hybrid but I bought it because I find running so boring, that and I get to make moto sounds as I ride/exercise.  I'm fortunate enough to live close to the ocean so I'm rewarded with a great view at the end of a 10 mile ride.  


Now I want a roadie and a beach cruiser that I can turn into a moto

Mountain or road? Fixed or freewheel?

I have horizontal-ish drop outs on my fixie (converted roadie), but it doesn't have a ton of adjustment, so I had to play around with gear ratios a bit to get the chain length correct. But if you have any issues fitting the chain with the gear ratio you like, 1/2 links for chains are available to compensate for funny chain length gear ratio combos. I geared my fixie for the steepest hill in typical commute (when I was employed...). I think it's 42/17 or something.

If its on a modern (vertical dropout) mountain bike, you may have to run a chain tensioner, 1/2 link, or if you could spend some money on an ENO hub, which has an eccentric axle to accommodate for chain stay length.

Good luck and have fun!

Yea its a roadie.. any idea on top speed per gear sets? I know rider strength factors in, my legs are pretty damn strong..  idea just poped in.. ill ride to work with thw big gear up front and see which rear cog feels best to ride all day and get that one..

Derrr, my math isn't that good.

Oh wait, here the interwebs is handy.
Gearing calculator for all your bike-geekery needs, just select the MPH@xRPM for the gear units.

Quick question on cycle computers.

I'm looking to get a GPS enabled device, like a Garmin Edge.

Anyone have experience with these or other brands to consider?

For the most part, I'm looking to be able to better track my rides without having to go to a website like mapmyride.com or google maps or what have you.

Although I'll probably buy a bundled kit (with cadence & HRM), I'm more interested in mileage and elevation gain, in addition to time, of course.  I do realize that if I start to pay attention to cadence & HR that it will help me become a better cyclist, but I'm not that guy (yet).

I had one of those for about 3 weeks - I was fortunate enough to have it stolen before I finished building it, so at least I don't really know what I'm missing!

Now that's a "glass is half full" way of looking at things.
