How Much Heavier Is 105 Than Ultegra?

Elevate Cycling |

When choosing between Shimano 105 and Ultegra, the first question many riders ask is: how much heavier is 105 than Ultegra? The answer might surprise you—it’s less than you think, but the difference can matter if performance and climbing are your priorities.

Weight Difference Between Shimano 105 and Ultegra

On average, a complete Shimano 105 groupset is about 250–300 grams heavier than Ultegra. That’s roughly the weight of a full water bottle or a multi-tool in your saddlebag. While the numbers may seem small, competitive cyclists often notice the difference during climbs and long rides.

Why Is 105 Heavier?

  • Materials: Shimano 105 uses more aluminum and steel, while Ultegra incorporates lighter alloys and carbon components.
  • Design Focus: 105 is built for durability and accessibility, while Ultegra prioritizes performance and weight savings.
  • Component Details: Cranksets, derailleurs, and brakes on Ultegra are subtly lighter without sacrificing strength.

Does the Extra Weight Matter?

If you’re a recreational rider, the weight difference won’t make or break your rides. But for competitive cyclists or anyone focused on climbing efficiency, Ultegra’s lighter build can provide an advantage, especially over long distances or steep gradients.

Shimano 105 vs. Ultegra: Key Considerations

  • Price: 105 is more budget-friendly, offering excellent value.
  • Performance: Ultegra feels smoother, lighter, and closer to Shimano’s pro-level Dura-Ace.
  • Target Rider: Choose 105 if you want reliability at a great price; choose Ultegra if you’re chasing performance gains and weight savings.

FAQs

1. Is Ultegra worth it over 105 for the weight difference?
Yes, if you care about performance, climbing, and smoother shifting. For casual riders, the extra cost may not justify the minor weight savings.

2. How much does the weight difference affect speed?
The difference is small in flat riding but noticeable on long climbs or during racing where every gram counts.

3. Do professionals ever use 105?
Rarely. Most pros use Ultegra or Dura-Ace for the weight savings and precision, but 105 is extremely popular among enthusiasts and endurance riders.

Final Verdict

So, how much heavier is 105 than Ultegra? About 250–300 grams. If you’re focused on value, 105 delivers exceptional reliability. But if your goal is performance and efficiency, Ultegra’s lighter build is worth the investment.
