New England Ropes / Maxim Aspire Gym 10.2 mm
Here's what other sites are saying:
The ElevateTM and AspireTM are designed to take the abuse and punishment that climbing gyms dish out. Both Gym ropes can withstand the tremendous abuse of multiple falls and heavy abrasion without compromising handling and knotability. MAXIMTM GYM ropes have TPTTM sheaths but with 33% thicker cover than any of our other climbing ropes The beefy cover can take whatever punishment you dish out.
