Shimano Titanium Bolt Kit TiNE 69.9 g vs 105 R7170 Ultegra R8170 Dura-Ace R9270 | TiNE
Three groupsets, three stock weights, one titanium kit. The TiNE Grade 5 Ti-6Al-4V bolt set for Shimano hydraulic road groups weighs 69.9 g regardless of whether you ride 105 R7170, Ultegra R8170, or Dura-Ace R9270. But the savings vary dramatically: 105 riders drop 109.4 g, Ultegra riders drop 75.4 g, and Dura-Ace riders drop 47.8 g. The same kit, three very different outcomes.
Why the Same Kit Saves Different Amounts
Shimano uses the same thread standards and bolt patterns across its 105, Ultegra, and Dura-Ace hydraulic groups. The titanium replacements are identical — same bolt count, same lengths, same thread pitch. What changes is the stock weight: 105 uses heavier steel fasteners across the board, while Dura-Ace ships with lighter (but still steel) bolts. The gap between TiNE's 69.9 g and the stock number widens as you move down the groupset hierarchy.

A 105 R7170 rider saves more than twice as much as a Dura-Ace rider — 109.4 g vs 47.8 g — from the exact same titanium hardware. The percentage tells the story: 105 sheds 61% of its bolt weight, while Dura-Ace drops 41%. The 105 kit is the single most cost-effective titanium upgrade in TiNE's catalog by grams saved per dollar.
What the Kit Covers
The kit replaces every serviceable bolt across the Shimano hydraulic group: shifter hose clamp bolts, caliper hose clamp bolts, brake bleed port screws, derailleur pivot bolt, pulley wheel bolts, front derailleur mount bolts with washers, and the caliper mount adapter. All Grade 5 Ti-6Al-4V, CNC machined, with eight anodized color options.
105 Riders: The Biggest Winners
If you ride 105 R7170, the math is straightforward. You are carrying 179.3 g of steel fasteners. The TiNE kit at 69.9 g removes 109.4 g — that is roughly the weight of a carbon water bottle cage plus two titanium cage bolts. No other single bolt kit on the market removes more weight from a Shimano-equipped bike.
Ultegra R8170 riders still save a substantial 75.4 g. Even Dura-Ace R9270, which ships with lighter steel bolts than the other two groups, sheds 47.8 g — nearly the weight of a titanium seatpost clamp assembly.
