3x8 Metal Garden Sheds | Tiger Sheds BUT a bike shed with a difference. A combined log store bike shed! Typical bike sheds are usually quite short in height and I felt not making use of the space above would be a waste. So my plan was to have a bike shed at the bottom and then use the area above as log storage. The problem was, no one sold anything that suited my brief � so I decided to make one. And of course, I�m sharing the full DIY with you. *This DIY is Sponsored by Roofing Megastore and contains some Affiliate Links. Here is my original sketch-up of the design with measurements. Our shed will be quite narrow as we only need.

I remember Nino Schurter winning on it within weeks of it being shown to the public, which was an early sign that 1X was going to pave the way for drivetrains to come. Fast forward to and 1X drivetrains feature on a large percentage of bikes. Today, we are going to analyse every aspect of bicycle drivetrains. We will be looking at all data available across nine different categories to find out once and for all, which drivetrain is best.

VeloNews has lab tested the resistance of both 1X and 2X drivetrains, and the conclusion is clear: 2X is the most efficient across all gears The main reason for the higher resistance is greater chain angles from the chainring to the cassette, which results in the chainplates scraping harder on the cogs. But additionally, when you use the smaller chainrings and cogs found on a 1X system, the chain tension is higher, the chain speed or tooth-interactions-per-minute is faster, and a chain has to articulate more to wrap around smaller cogs.

That said, there is also data available suggesting that SRAM chains run slower than Shimano chains , so the drive efficiency number might be a touch less � perhaps as little as 0.

Cadence is the number of times your cranks spin per minute when you ride. And just like your car engine, you will have an ideal RPM range where you can pedal efficiently. My preference is to pedal along at somewhere between 80 and 90RPM. In an ideal world, our cadence would remain constant as we increase in speed, but this is not possible on a bike with gears.

The next best thing is to make the difference between gear changes as small as possible, so you can stay in your optimal RPM range for longer. We can do this by minimising the gear steps between each cog on a cassette. But gear steps are pretty abstract, so I prefer to graph them using cadence differences.

These graphs show the specific range of speeds for each gear between two selected RPMs. A crossover in the graph signifies smaller cadence differences than those selected, while any gaps in the graph result in bigger cadence differences.

At my typical cadence, an upshift on a 1X12 drivetrain will slow my cadence by 13RPM. A great way to visualise gear range is to peg the lowest gear at a set speed for all drivetrains and then calculate what the top speed will be.

As expected, the weight goes down when you reduce the number of individual components in a drivetrain. However, the difference in weight between 2X and 3X is much less pronounced. As I specialise in bike travel, parts availability and compatibility is an important aspect of any drivetrain for me. Available spare parts usually go hand-in-hand with the bikes that shops sell.

While 8, 9, 10 and speed drivetrain users can mix-and-match between brands without much concern, speed SRAM uses oversized chain rollers to mate with their cassettes, and speed Shimano only really works well with Shimano, which limits your options a bit.

There is a misconception that newer, narrower chains commonly found on 1X drivetrains are not as durable as previous drivetrains. Zero Friction Cycling has done a lot of testing in this space and has found that speed chains are actually the most durable chains ever created, and not by a small margin either.

This is due to advancements in materials engineering, metal hardening and coating treatments. More than 30 chains have been tested by Adam on a converted smart trainer w resistance, 90RPM with lubrication and contamination controlled.

The test is stopped when the chain reaches 0. High-quality speed chains are lasting to km in this test, with equivalent speed chains running closer to km. For 8, 9 and 10 speed chains, the accelerated wear starts at 0. You can reduce chain wear by riding in dry environments, by keeping your chain super clean and by using a wax lubricant.

According to Zero Friction Cycling, you should get three chains to one cassette, and as many as six chains to your chainrings. By knowing when a chain will get to 0. Assuming an environment with similar conditions to those controlled for by Zero Friction Cycling, the bikes with front derailleurs and fewer speeds should be the cheapest to run. For a beginner, there is no doubt that a 1X drivetrain is the easiest to use.

If you want to go faster, you go up a gear, if you need to go slower, you go down. In comparison, using a 2X or 3X drivetrain takes a little more practice. Additionally, something that is easy use should also be easy on maintenance.

With fewer drivetrain components, 1X is the obvious winner here. Both the front derailleur and inner chainring chainline can interfere with the rear tyre, restricting how short the chainstays of a bike can be. Usually, shorter chainstays are preferred on mountain bikes as they make it easier to lift the front wheel over obstacles, as well as making the bike feel more playful to ride.

In this head-to-head, the 2X and 3X drivetrains took home five points, while the 1X setup ended up with four. The newest kid of the block, 1X, is certainly more user friendly, and the top-tier speed chain durability is incredible. For mountain bikers, 1X allows for frame designs with fewer compromises, and if you spend a lot of your time on steep terrain, the bigger gear jumps will not be particularly noticeable.

However, the case is as strong as ever for front derailleurs, as they provide a lower drivetrain resistance, a wider gear range and a smaller cadence difference between each shift. Bike Gear Gear.
