All the elite riders I have encountered just know. I think its part of the attention to detail necessary at that level. You almost never see them looking down to check (that would be showing a weakness and giving oponents an opportunity). But if you mean can the rider say which cog they are using at the front and rear? then the answer is that often we can'...

On or off road, but especially off road, it is desirable to be able to shift down more than one gear at a time to deal with abrupt changes in gradient and avoid being stuck in too a high a gear and stalling out. Also (as you mentioned) if you are required to slow down or stop suddenly, it's convenient to be able to drop down several gears while ...

Cadence mostly. The answer to your question is in the title. Experience. Same way motocross riders know what gear they are in. The speed of the engine vs how fast they are moving.

Unfortunately you cannot do that. The COGSET and the SHIFTER must have the same "distance", or more correctly, the same lateral distance (on the pulley) for each lenght of cable pulled (on the shifter). When you go from 7 to 8 speed, the distance between cogs is the same (because the freehub shell is longer), so you could use a 7 shifter with an 8 cogset ...

Cycling gloves are designed for comfort and to improve grip by absorbing sweat and providing a contact material that provides grip even when damp or wet. Typically, hands do not sweat much so most cycling gloves will help in this regards.

One point that seemed to be missed in the answers so far (though I'll admit I didn't read every word) is that indexed shifters are only a small part of indexed shifting. It used to be that you needed friction shifters because, in order to shift to a larger sprocket, you had to "over-shift" substantially -- push the lever beyond the point where it would ...

20,000km's in 2 years on Ultegra Di2. It performs very well. Shifts are smooth, crisp, quick and effortless. I have a few other road bikes running various mechanical shifters, but have preferred the electronic shifters during the past two years. No need for adjustment due to no more cable stretch. The front derailleur auto trims and follows the rear ...

Depending on the year of your Giant Escape 3, it either has Shimano EF40 or EF41 shifters. Both shifters have the same User Manual which has this information on downshifting: Assuming you are talking about your rear derailleur (right shifter), to shift 1 position you need to push the lever a small amount. Pushing the lever more will cause it to shift 2 ...

The new Claris, called R2000, has internally routed brake and shifter cables, an improvement on a previous version, that still sported the externally routed shifting cables. It is still 8 speed group, so in line with the op's wishes. https://bike.shimano.com/en-EU/product/component/claris-r2000.html dealers manual, page 13, how to install shifter cable: ...

It's a hack, but you can do this with the current Claris ST-2400 3x8 levers using an alternate cable mounting position on many "classic" shaped Shimano rear derailleurs. (Make sure whatever you're buying says 3x8.) Sheldon Brown goes into this briefly here. It tends to work fine in this combination (8-speed shifters on 7-speed.) Note that all shift-...

With friction shifters this is usually caused by one of two problems: Loose Shifter Screw: Friction shift levers usually have a wing-nut-screew used to adjust the tension and friction of the lever against the mounting housing. Tighten this screw, but not too tight or else you can't move the shift lever. You can also take the shifter apart (noting ...

No. The full gearing ratio of the bike (from your foot to the tire contact patch) is determined by four factors: the crank length, the chainring diameter, the cog diameter and the wheel diameter. Since these components can be changed independently, it is impossible to develop a uniform numbering system for a single component ("uniform" in this case means ...

The parts that Blam refers to are known as the pawls and the ratchet inside the freehub. Slipping can happen for a number of reasons, including worn ratchet, worn pawls, weak springs, or excessive accumulation of grease & grime within the freehub. http://dirtmountainbike.com/features/work-freehub-body.html has a thorough explanation of the different ...

One of my bikes has no indicators and I'm less familiar with it than my other bike which has indicators and more years especially at the top. But I don't find it to be a problem. You don't need to know exactly which gear you're in, just enough to know (e.g) that if you want to drop a gear you need to drop a chainring. A combination of feel and a vague ...

Rode downtube friction shifters bikes for a while. I can see two possible causes : either the shifter was too lubricated, or the screw isn't tightened enough. Try to tighten it more, but pay attention not to tear the screw. Usually the lever is pretty rigid when moving. If it's easy to move it to the point it moves alone, it's probably because it wasn't ...

Beyond the question of finickiness of actually using the system with higher cog counts, it's a matter of whether there's enough total cable pull from the shifter in friction mode to cover the range of movement needed given the cassette used and the actuation ratio of the derailer. Here's an excellent article with the basic data you need to figure it out, ...

There was a remote shifter available for ST-M952 and SL-M952 and some others of the era, so you could shift from your bar end. It actuated the main shifter via cables and housings. This is a stop for the housing.

The typical way of using a Shimano IGH with a dropbar is using a device called a Hubbub. It is essentially a little handlebar that plugs into the right hand side of the drops and gives you a mount for the usual twist shifter which comes with the IGH (This is what I would recommend). Another alternative is mounting it on the center of the bar with an extender ...

No, it's set up the right way. (In fact, because of the way the front and rear gear systems work, it's essentially impossible to set them up backwards: you'd have to re-engineer the whole system.) Think about it in terms of how many times the wheels turn for each turn of the pedals. When you change to a larger-sized cog at the front, the chain moves ...

For those who aren't familiar, a SRAM Automatix hub is a 2-sped internal gear hub which shifts automatically, with the shift mechanism and everything contained in the hub. The mechanism is mechanical, and there aren't any batteries or anything involved. So, no cables to the back of the bike needed except for a brake cable if you have a freewheel Automatix (...

A thumb /trigger shifter has been developed for the Rohloff speed hub. It has been manufactured by Cinq5 and is called Shift:R. It involves two levers one for up-shifting and one for down-shifting. I assume it will take some ride time to get used to the new and some what unusual methodology. They are not inexpensive. Reviews have pros and cons so you would ...

WD40 will work, for awhile, but in the longer term it'll work against you since it's a poor lubricant and will work to prevent future lubing. Spraying some penetrating oil into the ratcheting mechanism is the way to go, long and short term. Gaining access by working the brake on the shifter and spraying, using a long neck attachment for better aim, into the ...

I would try to avoid rim brakes for a low-maintenance commuter bike, because they're not low maintenance. And they don't work very well in the rain. They're also not much cheaper than cheap disk brakes. It's not worth the price difference. In my experience the roller brakes are less effective than disks or drums. The roller brakes don't bite, they're very ...

Well, I tried soaking it with WD40 and then re-lubing it with spray lithium grease. No improvement whatsoever. So I took it to the LBS, which declared it DOA. They say they've seen this before with Shimano shifters. Some internal part gets even slightly bent and the shifter fails completely. And they're not really serviceable, so that means replace it. ...

I-spec is a Shimano-proprietary mounting system for Shimano parts. Its supposed to make mounting and adjusting brake+shift levers faster and easier by putting them on one mounting clamp. I couldn't find a blurb on what it does / how it operates on the Shimano website, but the equivalent for SRAM is SRAM Matchmaker, which from their website: "The ...

Microshift is a brand. They are Taiwan base. Most of the twist shifter operates in similar manner as you described. They are for trimming as Batman said. But in fact it is made from the same machine and parts to keep the cost down. It is all about how to set up the front derailleur in your system, and find a spot for each appropriate gearing. i.e. avoid ...

It's not uncommon. Some Shimano shifters are prone to breaking off near the head in the shifter and it can be a bugger to get that little bit out of the shifter. My wife has Ultegra 9sp and I have to replace her cable about every 12-18 months. She can now tell when it's beginning to fray because the shifting gets dodgy before it completely breaks.

You don't have to buy Campy brand cables, but you do have to buy Campy-compatible cables, because they use a head that's a little bit smaller for both shift and brake cables. If you ignore this, it can seem like it's fine, but get stuck in your lever. The alternative in a pinch is taking a little off with a grinder or file. Most shops will have individual ...

A quick google research lead me to this article about comparisons of Campy and Shimano cables: Campy / Shimano Cable Comparison: Brake cable end fittings: Shimano "mushroom cap" diameter: 0.238"(6.05 mm) Shimano "shank" diameter: 0.140" (3.56 mm) Campy "mushroom cap" diameter: 0.214" (5.44 mm) Campy "shank"diameter: 0.138" (3.51 mm) ...

It's a knob that allows you to switch the shifter between SIS mode and friction mode. I discovered that here where they have images of the user manual for this shifter or a similar one: SIS stands for Shimano Indexed Shifting, which is the type of shifting most riders of newer bikes are familiar with - clicking between gears by number. Friction shifting ...
