Description
The IMS Big Bang is the latest innovation from IMS with fewer and smaller holes with a slightly smaller hole pattern, with holes getting closer toward the centre of the basket and holes do not go to the edge like IMS baskets.
The FH in the code means flat base. BB stands for big bang hole-boring pattern.
Most IMS baskets have 715 holes and 1.75mm holes – the BB has 585 holes and 1.50mm holes
The basket’s hole pattern is unique due to the hole spacing – which gets smaller as you get closer to the centre. This Big Bang pattern enables more flow through the centre to offset side channelling.
- You will have to make the grind finer with this basket to avoid soupy pucks (or increase the volume by 1-2 grams).
- This basket has no ridge – so you may have to adjust your existing PF spring if this is loose on your PF.
