How to upgrade Scale 930 to reduce weight and gain speed?

If weight is your main focus, compute the g/$ per upgrade and prioritise upgrades over that. The crank and cassettes are also easy ones on that regard. If the cost of the upgrades is greater than the ...

What bike should I buy if I want to fit a child seat and live in area with a lot of hills?

I liked a rear seat, and after the toddler size one (Hamax Siesta), I fitted a bigger one for another couple of years. I fitted mine to a hybrid with a wide range of gears (3x8, nearly as low at the ...

I think my MTB chain is modified ( shortened )

We can't know, there are too many variables. There are however plenty of methods to determine a suitable chain length. One of the simplest is to make sure that it's just long enough to go round the ...

Which full suspension bike is this?

Fairly common late 1990's 'copy' of the original Specialized FSR Stump jumper, using a single pivot rather than the Horst link Specialized used (which was patented back then). Several manufacturers ...

Is my shifter numbered backwards?

The gear numbers for both front and rear shifter are indicative of distance per pedal turn, which in mechanical terms is measured in ratios. Similar to a car gear box, in which case the higher the ...

What bike should I buy if I want to fit a child seat and live in area with a lot of hills?

I don't have experience with child seats, but do have experience with rear mounted racks, which I once loaded with more than 20kg on a hybrid bike (MTB frame with rigid fork and 26 x 1.5 tires), and ...

Is my shifter numbered backwards?

I don't think about the number of a gear when riding. Instead - know that pushing the lever one way makes it easier (for starting or going up hills) and the other way makes it harder (therefore ...

Occasional weird sounds from rear of bike

Occasional weird sounds from rear of bike

Your plastic spoke protector is rubbing against the cassette. When you pedal the two are not moving relative to each other and the noise stops. Squirt some WD-40 between cassette and disk and listen ...

Clunk/Knock noise when pedaling

If it's only when pedaling I would guess it's coming from the bottom bracket. After a wet ride or washing your bike water often penetrates the bottom bracket and allows things to shift slightly making ...

My mountain bike has 26 x 2.35 tires on it and I am ordering new 26 x 2.125 tires

Your new tires are a little bit less wide, and thus less high than the ones before. You will not face any problems, but technically, if you have a speedometer, the readings will be slightly off. With ...

Which full suspension bike is this?

Clearly the old shock was removed and replaced with a rigid link. Maybe the original failed, or maybe the frame design would bob unpleasantly while pedalling. Assuming the bolts are secure, this mod ...
