Add some versatility to your Micro with the new Micro springs! 

The Micro Grey Spring tension ranges from 7.5 LBS to 40 LBS when fully extended. It is heavier than a black spring, yet lighter than a red spring, making it the perfect in between tension to use alone or with other springs.

Important Notes:

• This item will ship within 5 business days from ordering.
• The Grey Spring is sold individually, so be sure to order two if you would like a pair.
• The Grey Spring is not compatible with the first version of the Micro, the Micro V1.
