Overview

The Broncolor 33.401.00 Speed Ring is the mechanical bridge between a Broncolor softbox and a Broncolor flash head — a component that sounds simple but has an outsized effect on how efficiently a studio operates. When you're rigging multiple modifiers under time pressure, the color-coded rod system is genuinely useful: each softbox rod snaps into its designated slot without rotating the entire assembly to check alignment. The speed ring locks the softbox collar securely to the flash head's bayonet, maintaining the softbox's angular relationship to the light source precisely as designed.

At 0.4kg and 7.87 inches across, this ring adds minimal weight and bulk to a softbox assembly. The construction is solid without being heavy — appropriate for a component that spends most of its working life supporting fabric modifiers on a light stand, subject to occasional knock and vibration. The included soft case is the kind of thoughtful detail that matters when you're packing out of a rental studio at midnight and trying to keep small metal components from scratching against each other in a kit bag. For photographers already committed to the Broncolor ecosystem, this is a straightforward system-maintenance purchase that simply works as intended.

Pros & Cons

👍 Pros

  • Color-coded rod alignment system dramatically accelerates softbox assembly during fast-paced multi-light studio setups where time between frames matters
  • Lightweight 0.4kg construction adds negligible load to the flash head mounting system, preserving stand balance with large softbox modifiers
  • First-party Broncolor engineering ensures precise mechanical fit and secure locking with Broncolor flash heads — no play or rattle in the connection
  • Included soft case protects the speed ring during transport between studio and location shoots where loose hardware in a kit bag causes damage
  • Compact 7.87" diameter fits within standard softbox carrying configurations without adding bulk to modifier transport

👎 Cons

  • Compatibility is exclusively Broncolor-to-Broncolor — photographers shooting mixed-brand setups cannot use this ring to adapt Broncolor softboxes to non-Broncolor heads
  • Softbox is not included, making this a supplementary purchase that adds cost to an already premium Broncolor system investment
  • At 7.87 inches in diameter, this ring is sized for specific Broncolor softbox collar dimensions — purchasing the wrong Broncolor speed ring model for your softbox size is a common error
  • The soft case, while protective, is minimal — dedicated hard-shell transport cases for speed rings require separate purchase for high-vibration travel environments
  • Limited utility outside the Broncolor ecosystem means it has no resale or cross-use value if you migrate to a different flash system

Frequently Asked Questions

This speed ring is designed specifically to adapt Broncolor softboxes to Broncolor flash heads. It is a first-party Broncolor accessory — it is not designed to cross-adapt Broncolor softboxes to third-party flash systems or vice versa. Always verify the specific Broncolor softbox model you own against Broncolor's compatibility chart before purchasing.
Broncolor uses a color-coded rod and receiver system so each softbox rod aligns with its matching slot on the speed ring. In a busy studio — working quickly between setups or assembling gear in dim conditions — this color coding eliminates the trial-and-error of matching rods to incorrect slots, reducing assembly time and preventing bent rods from forced misalignment.
Yes — it includes a soft case for protection during transport and storage. For photographers who travel between locations or pack gear into bags where metal-to-metal contact can scratch or bend components, the included case is a practical inclusion at this accessory tier.
The speed ring measures 7.87 x 7.87 inches (20 x 20cm) with a height of 1.46 inches (3.7cm) and weighs 0.88 lbs (0.4 kg). The lightweight construction means it adds minimal overhead to the softbox assembly without stressing the flash head's mounting point.
No — the softbox is sold separately. This listing covers only the speed ring adapter. You will need to purchase a compatible Broncolor softbox independently to complete the modifier assembly.
