SRAM RED AXS Titanium Bolt Kit 61.3g vs Shimano 105 Shifter Clamp 22.8g

TiNE makes titanium bolt kits for both SRAM RED AXS and Shimano groupsets. The Shimano 105 R7170 kit saves 109.4g; the SRAM RED AXS kit saves 61.3g. On paper, Shimano wins by a wide margin. But the raw numbers hide a more interesting comparison — and a single component that flips the narrative.

Total Savings vs Reduction Ratio

SRAM RED starts lighter — 139g versus 179.3g — because SRAM already uses lighter alloys and fewer steel bolts in their flagship groupset. The TiNE kit replaces what remains, but there is less excess to cut. A 44% weight reduction from a top-tier groupset is still substantial; it just does not look as dramatic next to the 61% from Shimano 105.

The Shifter Clamp: 22.8g From One Pair

Here is where the SRAM kit shifts the story. The TiNE titanium shifter clamp rings weigh 9.6g per pair versus the stock SRAM RED clamp at 32.4g — a 22.8g reduction from a single component. No other individual bolt or clamp in the entire TiNE catalog saves more weight per part. The Shimano 105 kit spreads its 109g across dozens of fasteners; the SRAM RED kit concentrates nearly 37% of its total savings in just one pair of clamp rings.

That concentration matters for riders who weigh upgrade priority. If you already run SRAM RED and are deciding where to spend first, the shifter clamp pair delivers the highest single-item return. The remaining positions — derailleur pivot bolt, brake caliper mount, crankset cap — each save 3–6g individually.

The SRAM RED AXS TiNE kit (77.7g) is heavier than the Shimano kit (69.9g) because SRAM uses more fastener positions — including the crankset cap and a larger derailleur pivot bolt that Shimano does not have in the same form.
