If you've ever dreamed of setting off on a bike trip with all of your camping gear then you've been bitten by the touring bug. While you can do this on almost any bike, a specialty touring bike like the Surly long Haul Trucker (LHT) makes everything so much easier. You don't go to the Indy 500 in a pick up truck and you would help your friend move in your 2 seater sports coupe. Bikes are the same way.
The Surly Long Haul Trucker is special purpose touring bike that will also do able duty as a commuter and grocery getter. Built from tough cromoly steel, the frame and fork are designed to take a beating. This is the kind of toughness you need if you get many miles from civilization. Quality steel is the best option for a touring bike as it has the properties of high fatigue resistance, impact resistance and great ride quality. As is the case with all Surly frames the welds are very clean and the finish is very durable. The color options aren't fancy but that's not what they are going for. Surly is all about function over fashion. Depending on your taste, the clean, utilitarian look is very attractive in it's own right. The LHT is at home crossing Canada or getting lost on the back roads of a third world country.
The geometry is optimized to be a stable ride with a heavy load. Long chain stays increase stability and give you more heal clearance if you are running extra large panniers. Laid back geometry and a long headtube create a fit that is comfortable for all day riding, day after day. There is a lot of tire clearance so you can bigger tires for more grip and comfort if you are on rough dirt roads and trails. It has cantilever mounts so you can run either cantilever brakes or v-brakes but be sure to mate the brake with the right brake lever.
Beyond the geometry and construction, what makes the Long Haul Trucker stand out is the details:
- It's has front and rear braze-ons for racks and fenders.
- 3 Water bottle cage mounts.
- Beefy drop-outs to resist wheel twist and bent derailleur hangers.
- Standard sizing for all parts such as seatpost, bottom bracket and headset.
- A spare spoke holder on the non-drive side chainstay.
- Studs on the frame so you can run downtube shifters, barcons or integrated shifter brake levers.
When it comes to the actual ride, the Long Haul Trucker likes to hold a straight line. It turns when you want it to but it doesn't require a lot of attention to keep it tracking straight. You would think it would be hard to handle a bike with 60 lbs of gear on it but the LHT handles beautifully full loaded. The ride quality is very smooth even over the roughest road. But on the downside, this stability comes at a price. Even unloaded, this isn't a fast bike. It wasn't designed to be but if you hop on it after riding your road bike it will feel like a bus. It covers the miles efficiently enough but doesn't feel fast.
My only complaint about the Long Haul Trucker is the lack of disc brake option. While not something you would want when touring in less developed countries due to the availability of parts it would be a nice option for touring in North America and Europe.
The Surly Long Haul Trucker is available as a complete bike or frameset to be built how ever you like. All sizes are now available with 26" wheel option. 56 cm frames and above are also available to fit 700c wheels. The option for matching wheel sizes at different frame sizes is of appeal to people like a married couple for touring together. While the frame sizes may be different, having the same wheel size means you only have to carry one sized inner tube or spare tire.
If you want a great performing touring bike at a reasonable price, the Surly Long Haul Trucker is one of the best options. Built from the ground up for the job, the LHT is a beast of burden that won't let you down.

Tuning Up Your Bike for Spring Riding
For those of us who put our bikes away for the winter, the time has come to dust them off and get ready to ride. When bringing a bike out of storage, a mini tune-up is necessary. Pay special attention to the following four areas: chain, derailleur components, brakes, and wheels.
~~Chain~~
If you have been using an oil-based lubricant, consider switching to a wax-based product. The only advantage to an oil-based lubricant is that it needs to be applied less frequently, but in every other way, wax-based is superior. For instance, oil collects trail dust and other things abrasive to the chain, whereas wax sheds abrasives. A recommended wax-based lube is White Lightning.
If you've been using oil-based chain lube, whether you want to switch to wax or not, you should remove the chain and clean it with a solvent to degrease it before adding fresh lubricant. Depending on your typical riding conditions, using a solvent to degrease the chain needs to be done once a year at a minimum.
~~Derailleur Components~~
Lubricate the pivot points using a good petroleum-based lube. I use Tri-Flow. Next, lubricate and adjust the derailleur cables, which might have stretched over the winter. Adjust so that shifting is crisp.
~~Brakes~~
Again, lubricate the cables. Use either petroleum- or wax-based lube depending on how dusty the expected typical riding conditions will be. Adjust the cables, which might also have stretched over the winter.
Check the pads: is there plenty of rubber; do the pads hit the rims evenly? If using fluid-actuated disc brakes, check the brake fluid level in the reservoir.
~~Wheels~~
Spin the wheel slowly checking for true. The wheel should not wobble at all. If it wobbles a little bit and you have the tools and skill, you can make minor adjustments using a spoke wrench. But if there is substantial wobbling, take the wheel to a shop and have a professional true the wheel.
Check tire pressure, which is bound to be low after a winter of storage. Inflate to the manufacturers recommendations that are stamped on the tire.
Now give the bike a once-over. Is the seat adjustment still a good fit? Is there excess play or tightness in the bearings of the wheels, crank, pedals, and headset? Also, for full-suspension bikes, check the suspension joints.
From this once-over, you will be able to determine whether it is time for a major tune-up. This could range from a few adjustments to cleaning and/or replacement of some parts. Opinions differ on how often a major tune-up is needed. It depends on how much you ride, and how much maintenance you perform yourself.
Whether you do the major tune-up yourself or take the bike to a reputable bicycle shop, every now and then the following maintenance is necessary for optimal performance and safety: repacking bearings and adjusting wheel axles, headset, crankset and pedals; replacing cables; truing the wheels; making overall adjustments, such as to the derailleur and brakes.

Also, you can use any front derailier that is designed for a tripple, so you may as well do deore.
