My Trek fx 7.2 has been making a clicking noise when riding for some time.However, it's been getting worse; it now makes a grinding noise if I'm mashing a bit when going uphill. İ check every possibility , the problem is bottom bracket .

And i want good qualty bb is this product good enough for daily riding ?
My bicyle L(51 cm) size ( if it necessary )
