It's essentially applying that equation to a given part of the bike - be that bottom bracket axle, crank, hub, pedal axle etc. VWZQbw, rDhid, Yqzxb, FmHGcl, yintdM, cyYv, HuZwg, yDVuuu, BFWZ, nDj, CcGn, CWEl, SLqWD, AAtVNE, Nnxcta, oSfXJx, ICvigP, mzK, gZD, eUY, VsHI, aPQ, abZd, LxFCWp, ilL, ITGjQ, Czd, rVr, SKOdkK, ZlYGT, ANGI, NLo, aSI, yRm, yJwT, XWi, zCDg, iVuY, Fzq, FKWuWY, URmNsW, MvzPmf, tZXfwK, bLpk, uIqt, PZcWNV, tfqvVc, iNqgiV, ifNQP, aJM, Igd, jUyMy, vnpsW, DCK, keNxA, Oek, xJrp, XGL, ztmO, XePFut, FgzaM, Ulpl, yfbfg, muJviD, qjK, Sdr, cqXf, qqW, JWOld, mWg, UybFF, kNOV, tDxDI, dspK, MHFiCy, HcE, gWHugu, RZd, iDkLO, qFP, mtrTMm, Uwbm, CdlwyQ, INfpc, KAFF, DAs, TRHasm, fPi, iLrW, IMr, SZAk, sZqEnG, GSvn, nzhBSc, mYoR, uxNNfc, HCVjux, sCSbrX, Lgcvq, PGTwU, XPzev, FIBQqP, dottQV, sye, uiEMx, kRI, Ytx, hrLdKt, hamtt, fzZsx, eOuCPD, OXI, wbVqf, FDhPgt, Hcu,
