What gears do pro cyclists use for climbing?
Pros often use a 55×11-tooth high gear for time trials. On flat or rolling stages they might have 53/39T chainrings with an 11-21T cassette. In moderate mountains they switch to a large cog of 23T or 25T. These days, they’ve joined the big-gear revolution like many recreational riders.
What gear ratio is best for climbing?
The best mountain bike gear ratio for climbing is 46 to 49 on a chainring and 16 to 18 on a cassette. For more diverse rides, mountain bike gears of ratios 46/17 to 42/17 are what work for flatter terrain or occasional hills. However, with that being said, the perfect ratio usually depends on the terrain you’re riding.

What does L and H mean on my bike?
Many shifters are marked in some way, often numbered or with an ‘H’ for the high gear and an ‘L’ for the low gear. The ‘1’ or ‘L’ refers to the innermost chainring (closest to the bike). This chainring delivers the least resistance and is useful for very steep inclines or soft terrain.
Do the Tour de France bikes have gears?
Every rider at the Tour de France will be on a bike kitted out with a top spec groupset with most now running 12 sprockets and electronic shifting too. While this doesn’t necessarily give them a greater gear range it does create smaller jumps between the gears and allow that perfect cadence more often.

Which cog is the highest gear?
The highest gear is when the chain is on the largest cog on the front and the smallest cog on the rear. Limiter screws stop your derailleur from shifting the chain too far inwards or outwards off the cogs. When set correctly they prevent the frustrating occurrence of the chain falling off.
What gear should you be in going uphill bike?
Low Gear = Easy = Good for Climbing: The “low” gear on your bike is the smallest chain ring in the front and the largest cog on your cassette (rear gears). In this position, the pedaling will be the easiest and you’ll be able to pedal uphill with the smallest amount of resistance.
