Bio Cell club lengths
Bars show the relative progression within this model, not a comparison with other clubs.
What the numbers mean
Playing length is a build specification, not a universal fitting target.
How this length compares
Only genuinely comparable Cobra entries are used; women, junior and ONE Length builds are not mixed with standard men’s builds.

About this length data
Cobra Bio Cell length FAQs
What is the Bio Cell length range?
The listed lengths run from 35.5 in (90.2 cm) to 39 in (99.1 cm), a total spread of 3.5 in (8.89 cm). The longest listed club is 3-iron and the shortest is GW.
How long is the Bio Cell 7-iron?
The listed 7-iron playing length is 37 in (94 cm). Across this model, that sits 2 in below the longest listed club.
How does length change through the Bio Cell set?
The listed progression generally gets shorter as loft increases. The typical step between adjacent listed clubs is about 0.5 in (1.27 cm), with a full longest-to-shortest change of 3.5 in.
How do loft and length relate in the Bio Cell set?
For the matched entries in this dataset, 3-iron is 20° at 39 in (99.1 cm), while GW is 50° at 35.5 in (90.2 cm). That shows the actual model-specific loft/length progression rather than a generic fitting rule.
What should I match when replacing the shaft on a Bio Cell?
Match the finished playing length for the exact 2014 Bio Cell configuration shown above, not shaft raw length alone. Grip cap, adapter/hosel installation and trimming can all change the final club length.
