This is one of those questions that can start arguments between bike mechanics--to cross or not to cross the derailer cables. Crossing appears to be becoming more common on new bikes, if the cables aren't internal, but it's also going to depend upon the bike. Smoother shifting is reported by some from crossed cables. I would talk to the mechanic at your LBS ...

The picture is a RD-M780-SGS long cage. Shimano have three codes for rear derailleur length: Short - SS Medium - GS Long - SGS I'm not aware of where this is printed on the RD though so not so helpful. However Shimano only have one non-clutched XT Dyna-Sys (10 speed) RD the RD-M780-SGS (long cage 43t capacity). The clutched (shadow+) RDs come in GS ...

I have seen this frequently and routed my cables this way. By routing the shifter cable from the right side of the handlebar around the stem to the cable boss on the left side of the frame (and visa versa) I create a more gentle bend in the in the cable housing. A gentler bend creates less internal friction on the cable. Another benefit is less stress on the ...

That is normal behaviour. You pushed the piston way out, so oil from behind it found a way out. General actions suitable for your case as well: remove wheel remove pads carefully push the lever a couple of times in order for the pistons to extend a couple of mms. if one is stuck, make sure you push the other one with a plastic tyre lever while pulling the ...

I don't know anything about bottom brackets, but I found this document which says (on page 16): Shimano cartidge-bearing bottom-bracket spindles are marked with letter codes that correspond to different length spindles. These codes and the corresponding spindle lengths are: Code Length MM 107mm and 110.5mm LL 113mm D-H 115mm YL ...

Trek Fuel ex8 - has hydraulic disc brakes. Hydraulic disc brakes do not require adjusting - they are self-adjusting. In that, as the pad wears - the distance between pad and disc is adjusted automatically. The squeaking and squealing of disc brakes is a common complaint. My first advice would be to - bed the pads in - make sure the discs and pads are clean ...

If you know the model and exact year Bicycle Blue Book is a good place to start. This is a link to all the models for Peugeot: http://www.bicyclebluebook.com/BicycleDatabase.aspx?make=718

The first thing to do is check the brifter out to see if its actually broken - maybe its just a cable broken at the brifter or inadequate cable tension or something. You can get your bike shop to check this out. If it is broken, you can look for people who specialize in refurbishing brifters (they do exist, but they are hard to find). As for replacement ...

You can use either the Sora or 105 shifters (all the cable pulls will match). Sora 9 speed has the proper ergonomics (instead of the silly button that it used to use on 8 speed), so its a good shifter. As for if you will notice any performance difference, both should shift fine (if the 105's are indeed in good condition) [if you're racing, maybe you'll ...

It sounds like you need to adjust your rear derailleur - the cable may have slipped a bit and have insufficient cable tension, or if you recently had a crash, you may have bent your derailleur. I'd recommend reading this to learn how to adjust your derailleur.

Couple of points:- Firstly, yes they are compatible. Yes they do shift better of standard cables, this is due to cable drag. Cable drag is basically the friction between the inner and the outer. This friction causes slower and less accurate shifting. The polymer on the inner decreases the coefficient of drag between the inner and outer, this increasing ...

According to BikeRadar, "The battery unit as well as the wiring for XTR Di2 are identical components to the ones used in Shimano's electronic road groups. The battery can be mounted on a bottle cage, in a seat tube, frame and can even be contained within the steerer unit of certain forks (via the use of PRO's new Tharsis components)."

I'm kind of confused here. You say you can only click 8 times. On a 9 speed bike, there would only be 8 clicks for shifting. Let's say you start on the largest gear, and we'll call that 1. Clicking 1 time with bring you to gear 2. Clicking 2 times will bring you to 3. Clicking 3 times with bring you to 4. Continuing on with the pattern will bring you on to ...

Shimano/SRAM 11 speed cassettes are wider than 8/9/10 speed ones. So yes, you need a new, wider freehub body, unless your old one was not very old and used a spacer to fit a 10-speed cassette. People with non-Shimano brand hubs are less likely to find replacement freehub bodies, it seems, leading to replacement of the whole hub, or even the whole wheel if ...

That bike is much older than 10 years. Probably somewhere in the '80s The bike pictured below is quite similar to yours, and was built in 1985. [Source: Peugeot 1985 product folder] Note however that these frames are generally of good quality, and if not terribly rusty can be used for many more years (and of course are very cool and retro looking). ...

You could: measure the chain stretch sight if the chainrings and cogs are worn out check the wear of the tires remove the seatpost and peak inside the frame for rust pull the brakes and inspect closely the cables for rust check the wheels for trueness measure the weight of the bike with an electronic scale rock the handlebars gently to check for drag in ...

You are right to say that the compact crankset will give you smaller gears to help you get over hills. You can do a straight swap of the crankset, everything else will be compatible, although will need readjustment. If you currently have a 5600 crankset, then you are absolutely safe to swap for another 5600 (compact) crankset. Now, the compatibility ...

You can find what you're looking for under names like "downtube shifter lever boss kit".. You should be able to find something at a bike shop (especially one which works on older bikes) or a frame builder. Another alternative is to use a clamp.

For that frame size, most likely 170mm, but you can measure from the centre of the pedal spindle to the centre of the BB: A popular online bike shop lists available crank lengths of 165, 170, 175, and 180. Presumably if you buy the bike "ready built" it will come with cranks chosen to match the frame size. But 165mm cranks are relatively rare outside of ...

According to Shimano's website, they are non-series components. However, some websites such as this one claim they are Ultegra quality (This wouldn't surprise me with Colin's answer). In any case, none of the Shimano long reach calipers are part of a series anymore. That being said, TRP (e.g. RG957) among others still make high quality long reach calipers ...

I can't see how a flat inside ring with no pick-up points machined into it wouldn't be compatible, providing the bolt patterns match up (which they do, I think). The bolt patterns are compatible. There are two reasons why the chainrings still may be counted as non-compatible: Not all Shimano chainsets have identical fitting of the chainring, ...

As you're not clear on road vs mtb, there's two answers. For 11 spd road drivetrains Shimano uses a 1.85mm wider hub with the drive side flange closer to the centerline to compensate for the additional width. Using a spacer allows the wheel to be backwards compatible to fit a 10 spd cassette. You can't fit a 11spd freehub in place of a 10spd freehub unless ...

The term for preparing the bottom bracket shell in this manner is called facing, and yes, it is necessary for all outboard bearing bottom brackets for proper function. To understand why this is, lets compare a hollowtech type system to a square taper cartridge. In the square taper, all the bearings and rotating portions are contained into a rigid metal ...

Yes, and Yes. Brifters will work fine and the cassettes will work fine. You can use any 9 speed Shimano road components in the drivetrain (crankset+chainrings with appropriate bb, chain, cassette, derailleurs) and the rear derailleur can be a <10 speed mountain derailleur as well. The chain can be made by KMC/SRAM/Shimano/etc. and the cassette can be ...

I managed to fix this, but I'm not completely certain why it started working. I believe the fix was a combination of three things. Repulling the cable and being firm about pulling it horizontally through the lever. I don't believe I got it deep enough into the lever before putting the hood back into place for extra pressure on the cable helped it engage ...

As I said in a comment, there are 25+ years of 105 and Ultegra (well, ultegra was called something else back then, but the line has been around for quite a while), so you need to find the right 105/Ultegra you're talking about. You can find the Product Info at this link. In 11 speed: The Ultegra RD-6800-SS and 105 RD-5800 SS both have a 28t max. Thus, ...

My answer is going to be a non-answer in the sense that shoe sizes are not really the same even among most types of shoes. As an example, when I buy shoes, I normally buy (in US sizes) 12.5 wide /13 in New Balance (which feels fine), 13 in Nike (which feels fine or slightly tight), 13 in Adidas (which typically feel tight), something bigger for boots ...

Actually I think you will find they are Ultegra, circa something like 2009. Since the technology trickles down you will find that they look like modern 105's. Take a look at the CRC product listings for examples of both the modern Ultegra and the old BR-650. http://www.chainreactioncycles.com/brakes?f=2259 Note: the 2009 is a guess based on ...

No, these brakes have nothing to do with Ultegra. A lot of unscrupulous Ebay sellers put unrelated keywords into the title to get more search hits. It's against Ebay rules, but it's pretty widespread, unfortunately.

Derailer adjustment is easy - at least in theory. When it comes to fine adjustment you may find that you cannot easily get this problem fixed without making something else worse - i.e. its a compromise. Its a good opportunity to learn how to adjust derailers- make adjustments slowly, one step at a time, and count the turns so you can go back to the start if ...
