| Peer Group Issuers, Footnote [Text Block] | The Peer Group TSR set forth in this table utilizes the S&P 400 MidCap Capital Goods Industry Group (“ Peer Group ”), which we also utilize in the stock performance graph required by Item 201(e) of Regulation S-K included in our 2022 Annual Report. The comparison assumes $100 was invested for the period starting December 27, 2019 (the last trading day of our fiscal year 2019), through the end of the listed year in the Company and in the Peer Group, respectively. Historical stock performance is not necessarily indicative of future stock performance. | | |

Tiers II and IV of the Pre-IPO Options vested in March 2022 and the Tier III awards expired in July 2022. The vesting of the Tiers II, III, and IV Pre-IPO Options was considered improbable until the vesting event occurred because vesting was contingent upon events outside the Company’s control. Accordingly, once vested, the Tiers II and IV Pre-IPO Options resulted in a change in fair value for these options equal to $16,825,131 for our PEO and $1,387,112 for the average of the Non-PEO NEOs in Fiscal 2022. For the values of equity awards included in the above tables, the valuation of certain stock option awards uses the same Black-Scholes option-pricing model with volatility assumptions that differ materially from those disclosed as of the grant date. The stock options were originally valued using a debt-levered model for the volatility assumption incorporating a weighting commensurate with the time Gates had been publicly traded. For purposes of this table, a weighted blend of Gates’ volatility and the average historical peer volatilities was used in cases where Gates’ stock price history was not sufficient to cover the expected terms of stock options being valued. | | |

| Measure Name | Adjusted ROIC | | |
| Non-GAAP Measure Description [Text Block] | We determined Adjusted ROIC to be the most important financial performance measure used to link the Company’s performance to CAP for our PEO and Non-PEO NEOs in 2022. More information on Adjusted ROIC can be found at the “Elements of Compensation - Long-Term Incentive Opportunity" section of the CD&A. This performance measure may not have been the most important financial performance measure for years 2021 and 2020 and we may determine a different financial performance measure to be the most important financial performance measure in future years. | | |
