If the total number of teeth decreases enough to add more slack than you can take up in your horizontal dropouts, then yes. @nsn

@nsn like the answer says: by swapping the chainring and cog for differently sized new parts (i.e., with different numbers of teeth). see this question about gear ratios: bicycles.stackexchange.com/questions/13191/…

excellent comment @freiheit. I've added that info to the answer.

Ramps for stunts? What do you mean by speed vs strength? In my opinion, you have to be pretty strong to go fast.

comment Bike lights with beam cut-off to avoid dazzling drivers?
Of course. My comment wasn't meant to be comprehensive. Just a quick comment with a link to some nice pictures. @ChrisH

I know the euro lights have this. I have a euro light! That's why I provided the link to the lights with which I have the most experience. (@ChrisH)

This design feature usually comes from the mirror and orientation of the LED, so it's hard to imagine meaningfully retrofitting a light. In particular, Busch & Muller lights are very good with this: peterwhitecycles.com/b&m-hl.asp

comment How do I make my frame water tight?
@Blam so is it even necessary then? Not sure that stuff even needs to soak for more than a few minutes.

comment Is an old mtb with replaced gear safe to buy?
Which bike is it? You said it has good reviews online, but don't link to any of them. It's hard to give an assessment with so little information.

comment Tightening a nut too much
I appreciate his sentiment, but Sheldon wrote that before you could get full suspension mountain bikes they weigh less than the road bike he had at the time.

comment Switching Parts to a New Frame
Typically, 120 mm spacing in the rear is for track frames, 130 mm for road, and 135 mm for mountain. I think 135 mm is becoming more common on road with frames that accommodate disc brakes, larger tires, etc.

comment Why are higher-end freewheels so much louder when coasting?
I seem to recall reading that Shimano designs their hubs to be quiet. Or perhaps it's that their hub design is inherently quieter. Something like that.

Great answer. I would like to mention that more points of engagement become particularly using with mountain bikes -- especially when ascending a technical section in a very small gear. I personally don't see the need on the road.

comment Why do spokes break?
@mattnz excellent point. i'll add a bit about fatique and try to keep it sufficiently high-level. let me know if i miss the mark.

comment Buying first hybrid bike; better to put $ into components or disc brakes?
hmm. then perhaps the answer should be clarified by saying, "in this price range, you'll likely want to avoid suspension and the quality of the disc brakes might not be satisfactory compared to ..."

comment Buying first hybrid bike; better to put $ into components or disc brakes?
does it rain a lot where you live? if not, i wouldn't worry about disc brakes. even if it does, it's a toss up, IMO.

I don't think the OP means mountain bike trails. Sounds like he's on paved (or at least well graded) multi-use paths.

comment Is front-suspension a false-economy for cheaper bikes?
Trials bikes don't come with suspension, but dirt jumper bikes do. My point is that it's not even worth mentioning (unlike non-subjective points like weight, maintenance, etc).
