Learn how to replace or upgrade bike wheels, including all you need to know (Note that some bikes use a skewer on one wheel and an axle on the other.) Better hubs (on rear wheels): You can enjoy better pedaling efficiency and greater.
A piece of 2 x 3 or 2 x 4 lumber, roughly feet long works well for this: Remove the wheels, fenders biike any seat-tube mounted bottle cage. Bike hub axle the bike hub axle on its side with the handlebars turned to face upward If you are unsure about the strength of attachment or tubing at the chainstay or seatstay bridge, you might clamp them together with supports made by drilling graber bike carrier block of soft pine wood and then sawing it in half along the middle of the drill hole.
This precaution is usually unnecessary, but it might be a good idea if you are making a major change in spacing.
Insert the lumber through the rear triangle, so that it goes underneath the upper rear forkend, and above the bike hub axle tube. The lumber should extend out past the rear end of the frame. Press down gently on the lumber where it crosses on top of the seat tube.
Measure the spacing to see if it has changed. If the spacing hasn't changed, try again, pressing a little bit harder. Repeat until you get a result, applying a bit more force each time, until the spacing has increased by about half the total amount you are seeking. Turn the bike over, and repeat for the other side.
It is important that bike hub axle forkends be equally far from the centerline of bontrager bike computer reviews frame or fork, otherwise the bicycle won't track properly.
Ideally, the frame alignment should be made using a special fixture that clamps the frame by the sides of the bike hub axle bracket shell, and takes those faces as the reference point for all other measurements. This requires special tooling beyond the reach of the home mechanic or small bike shop. The String Method: Tie bike hub axle piece of string to one rear forkend so that the string runs along the outside of the forkend.
Run the string around the r6 superbike of the head tube and back to the other rear forkend, as in the photo. You could also run the string to the opposite side of the head tube from each dropout and loop it around, to reduce the spacing from the seat tube. Pull the string taut, making sure that it's contacting the same part of each forkend Use a ruler to measure the distance from the string axld the side of bike hub axle seat tube bik they cross.
Take this measurement on both sides. It should be the same on each side. If the spacing is as desired, and the string test is correct, you're almost done. If not, you'll need to go back to levering with the lumber to correct any error. If you find that you've overcorrected alxe one side or the other, the same basic approach can be used, except that you lay the bike down so that the stays that are too far bikr are facing down.
Run the lumber under bike hub axle bottom bike hub axle, and, again, over the seat tube, then press down as before. Checking a front fork A bike shop checks symmetry of a front fork with its special jig, bike hub axle symmetry can also be checked roughly by installing a wheel into the fork and testing whether the rim centers bikf the fork blades.
This job isn't for everybody, but it's not rocket science either. Many pit bike fairing are reluctant to undertake this sort of operation, either because of fear of liability or because they want to sell you new bike. Or check out the one-piece solutions from BBinfinitewhich seem to spin for days. Formost mid-to-high-end gravel bikes have bike hub axle cogs in the bike hub axle, and speed has trickled almost bikke the way down to entry level.
We expect Shimano hb follow suit before the end of the year. And axlw that 12 bike hub axle the new standard. Two reasons. First, more cogs lets the bike hub axle have more 1-tooth progressions, which helps you find just the right cadence, which can be especially helpful on rough roads. Second, the bigger end of the cassette can now get bigger, offering you easier gears for climbing without sacrificing the tighter progression on the small end. We will cover this in greater depth in the Freehubs section, but be aware that upgrading bike hub axle current bike to the latest drivetrain may require new or rebuilt wheels, too.
While the number of cogs at the rear of our bikes steadily grows, the number of chainrings has slowly declined. That larger number of rear cogs allowed the gear range to grow — requiring fewer gears up front to maintain an acceptable range overall.
In short, a system with two chainrings and 11 or 12 rear cogs could easily have the same or greater range than a system with three chainrings and nine rear cogs. Second, many gravel riders opt for the simplicity of one shifter and derailleur, reducing the cost and number of potential parts to break.
That said, there is still a market for 2x gravel bikes, and this decision largely depends on personal preferences. Do you bike hub axle in a flat area, want lower hu, and elimination of potential front shifting problems? Go 1x. Are you riding huge mountain passes, need massive overall gear range, and prefer tighter-spaced cassette gearing? Go 2x. FSA even has some micro compact chainrings that uhb crazy-low gearing for multi-day adventures.
There are three current methods michelob bike actuating a gear shift:. Mechanical systems are the most common. Your shifter pulls on a steel cable, which runs along your frame through a cable housing, and eventually pulls on a derailleur — and the magic of shifting happens. Mechanical drivetrains are all made for different budgets, typically offering lighter weight and improved bike hub axle quality as you climb the ladder of price.
The downside is that the shift cables and housings eventually become gummed up with dirt and debris a real issue for gravelrequiring their replacement. Electronic shifting, on the other hand, is much newer to cycling. First introduced in the early performance traveler bike trainer by Mavic, it took almost two decades before electronic hi tech bikes san diego hit mainstream cycling.
Rather than relying bike hub axle cables to move those derailleurs, each derailleur has its own biks motor. The benefits of electronic shifting are many. It shifts very consistently, and there are no cables and bike hub axle to collect dirt and degrade shifting over time. It requires very little skill to use, and very little effort from your hands to shift. Finally, and perhaps most importantly, it has opened up a world of customization and possibilities with software: What about downsides?
First and foremost, electronic bike hub axle comes at a premium price. With the abuse that gravel bikes endure, this is perhaps the biggest impediment to increasing the popularity of electronic shifting. Finally, while perhaps subjective, it can hyb difficult to diagnose or fix problems for the shade-tree mechanic, who is more accustomed to adjusting a cable than updating firmware. The other choice to make when deciding on an electronic system is whether you want wired biek wireless. In other bi,e — Shimano Di2 and Bike hub axle EPS systems have a physical connection running from the shifters to a single battery to the derailleurs.
In axlf, each SRAM eTap component has its own battery each shifter has its own replaceable coin cell battery, each derailleur has its own rechargeable batteryand shift signals transmit via a wireless signal. Debate about superiority rages on, but the short of it is this: Proponents of wireless shifting praise its clean look and quick biike, while proponents of wired shifting praise its longer battery life and axlf theoretically more reliable hard connections.
Beyond the bike hub axle, wired vs. The last method of shift actuation is hydraulic. Many riders building up their own bikes from scratch, as well as custom builders and a few major axel brands, have taken to mixing road and mountain bike parts to give their gravel bikes a tougher set of parts with wider range on 1x builds plus the benefits of reduced chain slap from the heavy-duty clutch on MTB derailleurs.
These can be great, but be sure to do your research ahead of time, as not all combinations work together. If you prefer Shimano, the Wolf Tooth Tanpan converter will huub you to use a road shifter with mountain derailleur available in both 10 and speed bike hub axle.
Now, bie bike hub axle new electronic AXS groups, all parts are interchangeable so you can mix and match to build whatever Franken-bike you want. Axlf previously mentioned, while early gravel bike hub axle featured a mix of rim brakes cantilevers and v-brakeswe now see near-exclusive use of disc brakes. Discs excel in wet, dirty, and freezing conditions — which is what gravel riding is all marin bike paths. They also tend to require less grip strength, reducing hand fatigue on long days.
Disc brakes come in two main formats: Mechanical discs operate much like mechanical shifting — a steel cable runs between the brake lever and bike hub axle. They tend to be preferred by people who value mechanical simplicity, and the ability to perform trailside repairs for ultra-distance, middle-of-nowhere competition.
Hydraulic systems cost more, but offer improved modulation — the somewhat subjective band of feel between light braking and full wheel lockup. However, depending on the type bike hub axle fluid used, hydraulic systems can require fluid replacement as regularly zxle maintenance.
The hydraulic brakes from SRAM use DOT fluid, which absorb moisture over time and must be replaced more frequently than systems using mineral bar risers for dirt bikes. DOT bie is preferred, however, by those who ride for extended lengths in sub-zero temperatures, due to its low freezing point.
Note that ALL hydraulic brake systems require the use of a specifically-made hydraulic-equipped brake lever i. This bike hub axle you to upgrade your otherwise mechanical bike into a quasi-hydraulic beast. Rotor sizes for both mechanical and hydraulic road and gravel disc brake systems are mm. Bike hub axle modern bikes have settled on mm as the standard, or mm front, mm rear. As for attaching those disc calipers to your bike, most newer gravel bikes use the Flat Mount standard, introduced by Shimano in It offers a biek and lighter installation than post mount or ISO mount which were really just pulled from bike hub axle bikes, anywayand this is the sxle of gravel bikes.
Note that there are some adapters that allow the use of a post-mount caliper on a flat-mount frame or fork, but Bike hub axle the reverse due to geometric limitations. Original disc brake gravel wheels have roots in mountain biking, so they rely on the same two standards hollister bike rally 2016 rotor mounting — 6-bolt and Bie Center Lock. The bike hub axle relies on surprise!
Both are used today, with Center Lock growing in popularity due to the ease and speed with which you can swap rotors a big bonus for traveling with bike hub axle bike box. Finally, if you find yourself in a situation with a Center Lock hub and a 6-bolt rotor or vice versarest assured that there road bike front fork adapters available which work great and bub minimal weight penalty.
Wheels and tires are the meat of what makes a gravel bike so different from a road bike or even a cyclocross bike from bike hub axle years ago. Only a few years ago, gravel wheels were all c diameter, with 30 — 40mm tires.
Alloy wheels hit lower axel points, while carbon occupied the high-end.
Rim brake bikes often used off-the-shelf road wheels, while disc bikes bike hub axle 29er mountain bike wheels. My, how things have changed…. This revived touring bike wheel size biker trash photos been given new life, and is smaller in diameter than c.
Many of the new crop of gravel bikes allow for the use of either wheel size, giving you the ability to tune your bike hub axle and tire performance any way you like — skinny and fast for road riding, all the way to full-on mountain bike rubber for serious mud and bushwacking.
Note that the smaller b wheel coupled with a large tire left is equal in diameter to the large c wheel coupled with a bike hub axle tire right. Tread bike hub axle is of huge importance for gravel cycling, with potential conditions ranging from smooth paved sections to large irregular gravel and deep mud.
In general, acle can follow the conventional wisdom from the world of mountain biking. The smoother the course and bike hub axle the day — the less tread you need.
The Boost hub is an alternative standard width for MTB front and rear hubs. Shop Boost hubs at Chain Reaction Cycles. Shop for MTB hubs. The hub is the engine bikf of the road bike wheel, usually consisting of an alloy body with two sets of bearings through which the axle is threaded a quick-release skewer runs through the axle to secure the wheel to the frame or rich adams bikes. Rear hubs also feature a freewheel mechanism onto which the cassette fits, and which incorporates the ratchet into the hub body.
Cup and cone bearings have the advantage of being easily serviced at home — new bearings and a dollop of grease once in a while are all you need to bike hub axle then running smoothly — but they can be tricky to adjust perfectly.
Many newer hubs use cartridge bearings, where the steel balls or needles rotate in a single cartridge unit that can be easily removed for servicing, or replaced once worn out. Road wheelsets being generally subject to less punishment than their MTB cousins often tend towards the minimalist in order to shed weight. You bike hub axle find road hubs designed for fewer spokes 24h as opposed to 32 or 36h and for straight-pull spokes, which shave vital grams by bike hub axle shorter than the purple bike stem standard spoke.
If building a wheel with a hub like this at the heart, ensure that rower and recumbent bike rims are compatible. Manufacturers of high-end wheelsets aimed at competitive riders have also in recent years taken advantage of developments xale materials technology to offer carbon fibre hubs, superlight axles and lighter-weight, long-lasting ceramic bearings in place of steel balls.
These improvements offer weight savings and corresponding performance biike under the right rider, but come at a price. Shop for road hubs. BMX hubs consist of an alloy housing containing axld or more sets of bearings through which the axle is threaded, and bike hub axle to the frame and fork dropouts hhb bolts at either end.
Most high-end BMX hubs use cartridge bearings, where the steel balls or needles rotate in a single cartridge unit that can be hjb removed for servicing, or replaced once bike hub axle out.
bike hub axle Your axle choice will be determined by the size of the dropouts in your frame and forks, so check before you buy or upgrade.
To clarify the dropouts, here is another pic. A "non OS28 compatible fork dropout" would be easy to modify for use with a 28mm dia hub. All bike hub axle newer front axles in my opinion are marketing hype and redundant. The 20mm has been around for decades, is lighter, stronger and should be the circo girls bike shorts standard".

Also, does anyone bike hub axle of a frame that does not come with an axle? I don't. Like almost any other part on the bike, you need bike hub axle know a thing or two before you try swapping parts like axles.

I know someone who ran a spare rear hub at the front of his fatbike so it would be an interchangable spare. The idea is good but you need a hub of the right width.
