Does not fit older shimano gear lever band on as threads are different

In addition, make sure you are installing the cranks correctly. Hollowtech 2 cranks are very robust and shouldn’t just spontaneously fall off. Loosen and tighten the two pinch bolts in very small increments, 1/4 turn max at a time. Make sure to alternate sides. It is imperative to use a torque wrench on these two bolts. If the tension is uneven, the crank ...

If your rings are still in good condition, it's likely that you can replace just the left crank. https://www.sjscycles.co.uk/cranks-left/ Lists some that are available now. If you have (as your model number implies) a Hollowtech II crankset, any mountain crank using the same system will fit. As the main spindle is quite a hard steel, it doesn't usually get ...

Do you need a 10 speed triple? Any more recent replacement of M622 shoud work (Hollowtech II bottom bracket). FC-M6000 should be absolutely fine. You just need to choose a double or a triple, just choose the appropriate variant (M6000-2 vs. M6000-3).

Tl;dr: use 700c or 29" 27x2.125" is very rare. 27x2⅛" would be more likely, and wouldn't quite be the same thing, but for tubes the answer would be the same. Generally though, 27" tyres are narrower than this, up to about 40mm or 1 1/2" Schwalbe says that for 27" tubes you should use 700c, which are very common. The bead seat ...

When you speak about "upgraded over time" I think you mostly mean "ages well". Every time I buy a bicycle I want to make sure that it stays up to date for as much time as possible. And I try to sell it before the technology behind it gets out of date. The scope narrows down to the frame, pretty much, but components are also important, as ...

Argenti Apparatus' information is correct and there are several different derailleur models that would work as a drop-in replacement for your old Altus. You should stick with a Shimano derailleur model that will be marketed as a 7, 8 or 9 speed. Here, and in today's modern bike lingo, "speeds" refer to the number of rear cogs as opposed to the ...

Good news. Shimano kept broad compatibility between their products, even between generations. An Altus derailleur from circa 2002 may be from a 7 or 8 speed (number of gears in the rear cluster) drivetrain. You can actually use any Shimano 7, 8 or 9 speed derailleur with a 7 or 8 speed shifter. Shimano used the same derailleur actuation ratio (ratio of cable ...

I think you'll find that the second most difficult component of a bicycle to change is a wheel hub (unless changing the entire wheel obviously). This means if you are interested in for example dynamo hub lighting system, you should try to find it as stock hub in an existing bicycle. The most difficult component of a bicycle to change is the frame. Changing a ...

I'm just going to point out some minor things the other answers have missed. The original question correctly pointed that you may be unable to change the wheel size, and you certainly can't go from small to big wheels because there won't be room. You will also change the handling in ways you didn't expect. Many gravel bikes are designed to accept 700c and ...

The problem I see with this line of questioning is that it assumes the existence of some ideal perfect bike that has every conceivable upgrade on it. Then you are measuring a bike you're considering buying against that ideal with the idea that you could upgrade part-by-part until you have the ideal. That just doesn't exist because bikes are built for ...

The bicycle's serial number is usually found under the bottom bracket. if you regard the serial number as equivalent to the VIN number on a car, then changing the frame makes it a new bike.

Any and every part of a bicycle can be replaced, including the frame. (Many people would probably regard a different frame as a different bicycle though.) You ask whether there are components that 'cannot be upgraded'. I think you are misusing that word. Anything can be upgraded, i.e. replaced with a equivalent but better quality version. I think what you ...

Certain parts of a bicycle are more easily upgradeable than others, while other types of upgrades require special tools, much more money investments or are limited to whatever standards are used in its design. For some parts, the opportunity of an upgrade coincides with the older part being worn out; in other cases, the replacement is not warranted by this ...
