WHAT B-GRADE MEANS
LESS PERFECT FINISH. FULL PERFORMANCE.
B-Grade products do not meet our usual presentation standard, but remain suitable for their intended use. Every listed unit has been checked before it is offered here.
THE TRADE-OFF IS PRESENTATION, NOT PURPOSE.
Marks can differ from unit to unit. The selected variant, intended fit and supplied components remain the things to check before purchase.

B-GRADE • 30% BELOW STANDARD PRICE
Fully functional. Cosmetically imperfect.
This is a genuine Original 2" GymPin that has been inspected and approved for normal use, but does not meet our A-Grade cosmetic or packaging standard.
Your item may have light scratches, minor finish or colour variations, cosmetic machining marks, or imperfect/replacement packaging. The reason for B-Grade classification differs between items. The standard product photographs identify the model and finish; they do not show the exact cosmetic marks on the item supplied.
Only items that meet GymPin’s functional and safety standard are offered as B-Grade. The imperfection does not affect the product’s intended fit or function.
Please choose the correct 8 mm or 10 mm selector-pin diameter before ordering. B-Grade stock is limited and this product is available only through its direct link.

BUY WITH CLARITY
B-GRADE QUESTIONS, ANSWERED.
What size GymPin do I need, 8mm or 10mm?
Measure the diameter of your existing selector pin or the weight stack hole. Choose the 8mm GymPin for machines using an 8mm selector pin and the 10mm GymPin for machines using a 10mm selector pin. If you use different machines, the mixed pair gives you one of each.
Is this different to the A Grade Original GymPIn
Not at all, you can do everything you can withthe B-Grade GymPin that you can with the A-Grade.
How much weight can I add?
The amount of weight you can add depends on the GymPin product, the machine you are using, the selector pin size, the weight stack design and the available clearance. The Original 2" GymPin has a stated maximum load of 60 kg. Always load the machine sensibly, keep the plates controlled and do not slam the stack. Being a B-Grade GymPin does not change anything.
