Keeping up with your chain

Hey Dudes!!!
Just a reminder to change your chain regularly otherwise this might happen to you.
This is a chaining from one of the Freewheel employees who attempted to get through the winter on  his chain, however, the winter have other plans. As you can see, those teeth are worn down to the nub. 
As a chain wears, it will wear out the teeth on chain ring, This can be prevented by simply changing your chain regulatory.
So don't let this happen to you!!!! 
Come on by Freewheel and have your chain checked by one of our skilled mechanics.

Notes from a Wrench: Caffeine and Bike grease

This week a member of Freewheel Bike decided to order some brand new cold coffee drinks to sell to costumers. We put the 12 illy brand cafe iced coffee cans in the front cooler along side the Coca-Cola and Power-Aid ready for the public.
Sure enough, two days later the mechanics in the back had consumed every last one. Just goes to show you that if you wish to bribe a bicycle mechanic nothing works better than beer or coffee.
And that's the way it spins

Notes from a Wrench: Magnets!!!!!

Our friends at Zipp have come out with a brand new spin (pun intended) on free-hub bodies. I know what you're thinking and no it't not one of those Fabian Cancellara motors. Zipp Wheels have come out with a rear hub body that uses magnets to eliminate drag. That's right magnets!!!!! And as the philosophers and poets of the Insane Clown Posse once said "Magnets how do they work", the Zipp Cognition rear hub is just as mystifying.

The hub works by "disengaging the ratchet mechanism when coasting" this reduces drag and make the wheel more efficient. And for only $3,800 a set it could be yours. I think the product is too new to really have a proper option on it's future in the bike industry, but I know if you don't like the hub you can always hang it up on your refrigerate with your kid's homework. But like Moonpies and the inter-web, I think this is going to be a game changer. Check out the hub online and tell us what you think.

And that's the way it spins

The Stache 9 - In Depth

I first rode the Trek Stache 9 at the Trek Factory Demo that took place at Lebanon Hills on May 24th, 2015. I was not expecting much from this bike; I rode it out of professional curiosity (it's kinda my job). 

As you can see it's a really hard job. Some days are harder than others. After about seven hours of setting up bikes for customers to ride we shut down the public demo and had a shop employee-only demo. I was pretty tired from adjusting air pressure on suspension forks and talking about bikes all day but Ken, the demo truck driver, insisted that I go ride a Stache. And since everyone that had ridden one came back raving about it, I knew it was my duty to check it out for myself.

The 18.5" Stache 9 at the demo had Trek's new HiLine 29er+ wheels on it, which are not stock. These wheels are reportedly much lighter than the stock wheels and of course they have Bontrager's legendary tubeless system. These were an early-release wheel set, and are not available for purchase at this time.

After riding the bike for one lap at Lebanon Hills during the demo, I was convinced that this was the right bike for me. This bike is fun! I quickly ordered one up while they were still in stock. The initial assembly of the bike was a breeze. With the 1x11 drive-train there was only one derailleur to adjust, the wheels were true, and the brakes set up quickly and easily. 

After the first ride I swapped the dropper post for a Cane Creek Thudbuster because I'm an old guy with a bad back. I found that with the suspension seat post and the plus-sized tires I was able to keep weight on the saddle through bumpy corners, which allowed me to keep rear-wheel traction (kinda like a full suspension bike--do ya see where I'm going here?). It also allowed me to stay seated over bumpy terrain and not lose my pedaling rhythm. Yes, I am still a hard-tail rider because it suits my style, which is to say that long sustained climbs are my weakness. This is one of the reasons that the plus-sized tires appealed to me. Some people have talked about hitting their feet on the stays. I do not have this problem when I am clipped in, but when goofing around on it in street shoes I do occasionally feel my heels hit the stays, but it's no big deal.

One of the things that I first noticed is that the Mule Fut rims were heavier, thus the bike was not quite as quick on the climbs. But as a clydesdale rider, I noticed more flex than on the Bontrager HiLine wheels that were on the demo bike I rode. I also had difficulty getting the rear wheel to set up tubeless. The wheels came stock with the Sun Ringle rim strip to cover the cutouts but they put Stan's rim tape over the stock rim strip to seal things up. The Stan's tape was just a little bit wider than the stock rim strip, so it kinda stuck to the rim. I ended up replacing the Stan's tape with duct tape, which is the perfect width at 48mm. This seems to have done the trick for now.

 One quirk to be aware of is the Manitou Hex Lock through-axle.

 It uses a hex shape to align it so that a "T" shaped tab can engage a slot in the cap on the rotor side. 

 It's a bit clumsy to use and seems overly complicated. But it works.

The Manitou Magnum fork has 110mm of travel, but with the quality of the suspension feel and the big tires I don't need any more. I haven't taken the time to learn about all the adjustments or do much tuning which is a testament to the fork because it feels good. The red knob is a lock out/firming adjustment and it works well. There's a high-speed compression and a bottom-out adjustment knob. I fiddled with them on my first ride but didn't notice much difference. One important note: to adjust the air pressure in the fork you DO NOT take off the black top-cap on the rotor/non-drive side; instead, you remove the blue bottom-cap on the rotor side. I will say that from setting up the bike at the Trek demo and from my experience I found that I preferred a much lower air pressure than what the sticker on the fork recommends. 

So why did I choose to get one of these bikes? This bike is what I have needed for the last 15 years. It soaks up the trail. It loves to lean. It is the perfect wheelie machine. It goes over rock gardens better than any other bike I've ridden. The positioning/fit is very comfortable yet I would still be happy to race on it. The bottom line is that it is a ton of fun and it's fast. If you want to give one a try, stop in to our West Bank or Eden Prairie location or join me on my Sunday Night Theo MTB Ride

Protect your derailleur hanger

From time to time we see a bike with catastrophic damage to the rear derailleur and rear wheel caused when the derailleur got caught in the spokes of the wheel while it was moving. Most commonly this is caused by prior damage to the derailleur and is COMPLETELY AVOIDABLE! Frequently we see telltale scuff marks on the outside of the derailleur itself, suggesting that it has been through some earlier trauma.

Here's how it usually goes:

1) The rear derailleur gets bumped, bending the derailleur hanger slightly in towards the rear wheel.

2) At some point the rider shifts towards the larger cogs (easier gears), at which point the derailleur cage gets caught in the spokes of the spinning wheel.

3) Terrible things happen.

The derailleur hanger is the small tab which connects the derailleur to the bike frame. On most modern bikes these are replaceable, meant to be a sacrificial part. Because they're meant to be the weakest part of that system (to avoid damage to the more expensive derailleur or frame), it takes surprisingly little force to bend them. Something as minor as tipping the bike over onto the right side can do it. Or maybe you didn't quite make it through that closing door on your way out of the bike shop, and the door bumped your derailleur. Or perhaps you were a little ungentle while loading the bike into your car. Needless to say, actually crashing the bike on that side can bend the hanger.

But the major damage often comes later, when you continue to ride a bike with a bent hanger. So be forewarned: it's much cheaper to replace a bent hanger than your derailleur and rear wheel.

Double Barrel comes to the Midwest

Ever heard of the Cane Creek Double Barrel? It's only the most adjustable, best-performing rear shock on the market. and it's coming to the Midwest! Shockspital is now a certified Double Barrel service and warranty center, joining just a handful of shops around the U.S. that are thus qualified.

And though the CCDB only comes in sizes 7.5" and bigger, any of you with a bike that can handle a long-travel shock should be excited about this product. Keep in mind that you'll need to devote some time to dialing it in to your preferences. While most rear shocks offer two or three types of damper adjustment, the CCDB offers four: high- and low-speed compression AND high- and low-speed rebound. And if you want the new Double Barrel CS, you also get a climb switch similar to the pedal platform option found on other companies' shocks.

For the more weigh-conscious rider, there is the Double Barrel Air, boasting all the same adjustability of the CCDB but using a lightweight air spring in place of the coil.

Of course this level of performance comes at a price--the Double Barrel is a bit of an investment. But fortunately for you prospective buyers out there, Shockspital is also an authorized Demo Center. This means you can try before you buy! Check out the Double Barrel website to see if your bike can handle this shock. If it can, give us a shout to line up a demo shock. We're still in the process of putting together our demo fleet, so contact us before it gets warm out to ensure we have the right size for your bike come spring.

Minnesotans/Wisconsinites in the audience should consider this the hands-down best choice of equipment for your Spirit Mountain bike. Hell yeah!

Double Barrel small part? Yes, we have that in stock.

Confessions of a Recent Fatbike Convert

When I joined the Freewheel team last summer, I knew that it would be especially hard for me to resist the allure of fat bike season once winter came. Now that I was working at one of the nation’s top fat bike retailers, I was surrounded by them, in more varieties than ever—our shop carries Trek’s new Farley, Salsa’s aluminum and titanium Mukluks, the super-wide Surly Moonlander, and the breathtakingly light Borealis Yampa and Salsa Beargrease carbon models. (“A carbon fat bike?” marvels every single person who enters our store.) And, of course, the stalwart Surly Pugsley, which kicked things off back in 2005 as the first retail fat bike.

Less than a decade later, the skyrocketing popularity of fat bikes is well-documented and nowhere more visible than the Twin Cities, where fat bike manufacturers are headquartered and hundreds of them roll out of our three Freewheel locations every season. Plenty of people even bought them during the summer, heading for the MTB trails. We are reaching Peak Fatbike, not just among trail enthusiasts, but with everyday commuters, as more brands make them and they become more affordable. (You know a trend has moved from the fringe to the mainstream when the local news covers it and Wal-Mart gets in on the act.)

I’ve been a winter bike commuter for years, and I still believe that nothing will get you through a Minnesota winter like a dependable old frame with studded tires, fenders, and platform pedals. But if you want more stability and relish the thought of an off-road adventure on your way home from work, you should consider a fat bike.

I was still on the fence about fat bikes when I winterized my single-speed Surly Steamroller in November. Then Freewheel held its Winter Bike Expo, and I spent two days watching Pugsleys, Moonlanders, Beargreases, and Mukluks roll out of our Midtown location and onto the course we’d set up on the Greenway. Maybe I lingered a little too long next to the Dillinger tires and W√∂lvhammer boots, or just saw too many ecstatic, rosy-cheeked customers return from their demo rides, but I eventually drank the metaphorical Kool-Aid by demoing a Pugsley on the course. I knew it was going to be fun, but nothing compares to the sensation of actually clearing a four-foot ramp or bombing down a big hill—using a bike to do something previously reserved for snowboarders. I was instantly hooked, and the Expo gave hundreds of others that conversion experience along with me. I purchased a Pugsley in “Real Blew” later that week.

Cyclists often describe the appeal of winter biking by invoking the intrepid spirit of arctic explorers and astronauts, striking out into inhospitable environments decked head-to-toe in funny-looking clothing, wearing big boots and facemasks. People who make fun of us or call us crazy for riding through winter probably haven’t felt the ways that riding in these conditions amplifies the usual mental and physical benefits of cycling: your heart beats faster, your body gets warmer, and you get out of the house, undaunted by the snow and cold. Fat bikes take these sensations to the next level by giving you added confidence on various terrain and the knowledge that you can hop that pile of snow at the next intersection if have (or want) to. You’re getting a great workout, combating Seasonal Affective Disorder, raising your body temperature far higher than you would driving or taking the bus, and having a blast in a climate most people flee by staying indoors or leaving the state altogether. You’re a superhuman James Cook/Neil Armstrong badass.

Of course, riding a fat bike doesn’t make you invincible, and there are some peculiarities to the machine that take some getting used to. For one, you’re not going to go as fast on pavement as you would on any other bike, especially if you keep your tires inflated at the extremely low (5-10 psi) recommend pressure. You’ll also probably be in the low gears for most of your ride, but that’s great news for your cardio workout! Fat tires sometimes have less traction than you’d expect, and can wash out on the mashed-potato slush that fills the streets after the plows have come through. Studded Dillinger tires can help with this and bestow upon your bike something approaching invincibility.

So, do you absolutely need a fat bike? Probably not. Do you want one? Definitely probably. My winterized Steamroller will get me from point A to B, but on the days when I have time to kill before or after work, or on weekends when I want to hit the trails, I’m glad I’ve got my Pugsley. A few weeks ago, grappling with cabin fever, I left for work a couple hours early and rode down to the East River Flats. I followed a trail that cross-country skiers had packed relatively firm, occasionally venturing out onto the ice, stopping every now and then to take in the scenery and be grateful that I had such ready access to the country’s mightiest river and the quiet that I relish so much during a winter ride. I was a couple miles downtown and just down the hill from the U of M campus, but it felt like I was in the middle of nowhere. My cabin fever was gone; I felt physically and mentally restored. That’s a feeling you can’t put a price on, but it’s got to be worth at least as much as my Puglsey.
