When To Replace<\/a> It is a feature series in which we explore when one should replace common cycling products like helmets, apparel and various moving parts on your bike. Curious about a particular product? Shoot us an email at anne.rook@futurenet.com<\/p>\n

Have you ever been in a group ride, sitting behind that one cyclist who\u2019s showing a bit too much skin through threadbare shorts? What about those compressive bibs that now wrap\u2014instead of compress\u2014your legs, mostly held in place by loosely fitting straps? Do you have cycling shorts that used to feel so amazing, with a chamois that was like no other, but now you feel like you cannot get them into position for most of a ride?<\/p>\n

<\/p>\n

When asked about cycling shorts<\/a>\u2019 lifespan, Castelli\u2019s Steve Chapin offered a circumspect and environmentally conscious perspective: \u201cIf you\u2019re still comfortable in the shorts, even with the less cushioned seat pad, then definitely keep riding it. No reason to fill up the landfills prematurely,\u201d said Chapin.<\/p>\n

But, shorts won\u2019t last forever. \u201cThe Lycra can break down due to high heat, exposure to chlorine as well as sunlight. Ultraviolet radiation causes the molecular chains of the polyurethane segments in Lycra to degrade, much like old rubber bands becoming brittle,\u201d Chapin said.<\/p>\n

\u201cThis leads to a loss of elasticity, fabric thinning, and permanent stretching out. The first place this usually happens is on the back of the short and when the Lycra degrades then you\u2019ll get some transparency back there.\u201d<\/p>\n

What are the timeframes?<\/p>\n

If you want to put a number on it, Scott Sports Marketing Director Chris MacKay pegs shorts\u2019 lifespan about the same as bike helmets<\/a>.<\/p>\n

\u201cFor most bib shorts made from polyamide\/elastane blends, you can expect about three to four years of consistent performance with regular use. Higher compression fabrics can sometimes extend that lifespan slightly,\u201d said MacKay. \u201cLongevity really comes down to two key factors: construction and care.\u201d<\/p>\n

And Gianluca Caliari, president of Nalini\u2019s U.S.A. importer Albabici, agreed with MacKay\u2019s suggestion regarding chamois<\/a> lifespan of about three years. \u201cCycling shorts generally need to be replaced after 10,000 to 15,000 Km (or after two to three years of regular use), as indicated by signs of wear and tear,\u201d said Caliari.<\/p>\n

The signs to look for<\/p>\n

Timeframes, of course, will vary by rider depending upon mileage and care. So what other signs can we look for? \u201cThe fabric may begin to look thin or slightly see-through, though that typically means they\u2019re already well past their prime. On the chamois side, watch for pilling on the surface, which can increase friction and lead to discomfort on longer rides,\u201d MacKay said.<\/p>\n

“A good pair of bib shorts will gradually tell you when they’re reaching the end of their life,\u201d MAAP representative Tom Copeland told us. \u201cThe biggest indicator is usually chamois fatigue. If the insert feels softer than it once did, or you’re starting to feel your sit bones through the pad on rides that were previously comfortable, it’s probably time for a replacement,\u201d said Copeland.<\/p>\n

Rapha Media Manager Sophie Poston offered a few clear indicators. \u201cIf the chamois <\/a>stops cushioning, the fabric goes thin or sheer, or the fit goes baggy, it\u2019s probably time to replace,\u201d said Poston.<\/p>\n

\u201cIf you’re getting saddle soreness you didn’t used to get and you haven\u2019t changed your saddle, bike fit or shoes<\/a>, trust that feeling over how the shorts look, that’s your cue,\u201d Poston offered. \u201cPinch the chamois between your fingers. If it feels thin, flattened, or doesn’t spring back, the cushioning is gone.\u201d<\/p>\n

One of the most obvious and prone-to-wear parts of cycling shorts are the panels above the chamois in the rear. \u201cBib shorts <\/a>should ideally be replaced well before the seat panel starts going sheer. When the rear panel starts offering more ventilation than compression, it’s probably time to upgrade,\u201d suggested Copeland.<\/p>\n

Rapha\u2019s Poston added: \u201cFabrics in the seat panel are particularly important as they have to be more resistant to abrasion from the saddle. If you notice there is pilling (or bobbling) it\u2019s a sign that the bibs are wearing.<\/p>\n

\u201cIf you notice fabric is riding up or sagging or the bibs don\u2019t fit like they used to, the fabric may have worn out. This might be particularly noticeable if the bibs change a lot during the ride and feel like a different product by the time you get home.\u201d<\/p>\n

\u201cFraying threads or separating seams\u201d are also a sign to look out for. \u201cIf seams have failed it could mean a moving chamois, which can lead to saddle sores and discomfort,\u201d Poston cautioned.<\/p>\n

Another indicator it\u2019s time to retire your favourite kit is if, after washing, they still smell stale at best. \u201cIf you find there\u2019s a smell that survives a proper wash \u2013 or it starts to smell not long after you\u2019ve set off \u2013 the bibs may be past their best,\u201d cautioned Poston.<\/p>\n

How to Prolong the life of cycling shorts<\/p>\n

\"Man\n<\/p>\n

Don’t tumble dry your shorts and wash them inside out to prolong their life <\/p>\n

It bears repeating: don\u2019t tumble dry your shorts the same way you\u2019d care for a terry cloth towel.<\/p>\n

\u201cAlways wash in cool temperatures and avoid heat. Heat is the fastest way to break down both the compression and the knit structure of the fabric, significantly shortening the life of the shorts,\u201d advises Scott\u2019s MacKay.<\/p>\n

Castelli\u2019s Chapin concurs, and reminds cyclists to wash shorts in warm water, and skip the dryer. Chapin said, \u201cOne of the main culprits is washing at too high of temperature and high-temperature drying, so please make sure to wash your shorts in warm water and then air drying.\u201d<\/p>\n
