I vaguely remember reading that spending time in an gear combo with a lot of diagonal distance wears chain faster.Nieghorn wrote:Yeah, pretty sure that's how it goes. I always think of it like a car. I'm not starting or going up a hill in the gear that makes me go fastest ... so small chain ring at the front and largest cog at the back is "1st" and as you describe above is "21st".Apposite wrote:That's probably a more sensible strategy alright on the gear front. Never know which is high or low on bikes, basically the bigger the front cog and smaller the back the higher gear, yeah? Higher gear more resistance, so 21st is big cog front/little back? Or is that first??Nieghorn wrote:
Regarding gearing, if you're in the highest gear of the middle chain ring, why not cruise in a 'lower' gear on the big chain ring? When I'm in the city, I'm usually in the middle while on the big, and then shift down to the middle chain ring at lights, flipping back up when I build some speed.
(For urban riding, I'd be better off with just one cog at the back and the three rings up front. I do fine on my single speed, but many downward slopes see me unable to pedal and there are a couple of hills in this city that I can't make up even standing to pedal, and with my weight.)
... though when I think about it too much, I imagine there is some cross over as middle / 5th is probably a 'higher' gear than top / 3rd, for example.
I try not to think about such things, though, as I've only just begun to learn about bike mechanics.
I think my bike actually has 27 gears, I use about 4.
