While searching for a good way to get Cal on my bike safely, I stumbled across this full carbon monstrosity:
The S-Works tandem
I think I am not alone in thinking that tandems are usually pretty lame, but this one is pretty darn cool! Check out the connection between the front and rear drive; while most tandem bicycles use a second chain to connect the driver and passenger cranks, Specialized has used a shaft to connect the two:
Not a chain in sight!
There is some confusion since there is no chain connecting the passenger crank and the back wheel. Overall this is a sweet bike! But if I were to get something to haul Calvin around in, it's more likely to be like this:
Enough with the weird bike b*ll sh*t, get to some building or wrenching posts.
Always great to hear from my fans. Fredo, you are in luck because I just picked up a steel 29er SS frame with a couple rust spots. Here's what you do to remove unsightly rust and keep your bike smooth and clean:
1. Examine Rust - Yep, it's rust. This bike has a lot of paint chips and dings. I'm addressing four of the largest areas that are rusting badly so it won't get any worse.
Inside the fork
Inside the chainstay
2. Sand the rust away - It's important to make sure all rust is gone, even at the cost of some paint. Any rust you miss will eventually peel off the new paint.
Inside the fork
3. Primer - This is important because the pain will stick better if it's properly primed. These are some hard to get to areas, especially without getting paint all over the rest of the bike. Paint carefully!

4. Paint - After the primer is dry, hit it with a few layers of paint. I like to put on the early layers more thin, and then increase thickness as I go. The last layers should be the thickest to get a good sheen.
The paint came out of the can a little... splattery for some reason, so this doesn't have an ideal finish. For the purpose of protecting the frame from further rust, it will work great.
5. Admire - I'm pleased with how this came out. I predict that this paint will last many rides!
Keep an eye out for more updates as this frame build shapes up.
Looking for that bike that says, "I don't care about performance, I only want comfort." Well look no further than a recumbent. But what if you're looking for a low performance frame with high performance comfort? Well then you'd be the target audience for a FULL CARBON RECUMBENT.
Behold it in it's glory
I'm not saying recumbent bikes are bad. I'm not saying that a full carbon recumbent with Zipp 303's and a SRAM Red carbon crank is a gross waste of money. All I'm saying is they're weird and the people that ride them are not to be trusted...
Check out these nipple single speed clamps! This is what a normal single speed spacer kit looks like. This is for when you aren't running a whole cassette, and only want to run one gear:
The spacer kit
This is what it looks like in action:
Single speed conversion
There are some options for different styles, for example this is a little more sleek looking:
2 piece spacer kit (with end cap)
Enter Gear Clamp. These guys are building a clamping system to convert to a single speed:
Gear clamp system
The verdict? In my opinion, it's a cool but overly complex answer to a solved problem. You'll get a tighter fit on your cog by using spacers and clamping from the end with the cap (from above). It seems like this would work its way loose frustratingly often. Someone write in and tell me why I'm wrong.
Casey Brown is a pro downhill rider from Canada, and she is intense. In the video below, she's trying to break 60 on her mountain bike on a trail in British Colombia. This trail is straight, steep and fast. What does she do to kick it up a notch? Takes her brakes off. Check it:
With all the material research and development in bicycles - titanium, carbon, magnesium - here is a refreshing study into a wooden derailleur. The project was taken on by Max Hoffman, a student working at a community bike shop. He took some parts and recreated a Campy derailleur with many of the parts out of walnut.
Wood and beauty
While this is a non functioning example (mounting stresses would destroy the part) it is an interesting insight into how the parts fit together.
I think one of the commenters said it best - "..in this day and age of carbon and titanium, it's cool to see a throwback to art." Thanks, once again to Bikerumor for the link to this awesome story.
Hopefully you're all enjoying the holidays as much as this guy. He and some friends rode all around San Francisco, tracking their ride with Strava. The route was designed to make this awesome turkey design! Check out the stats though...
