Nothing is perfect. Even your fancy new bike might not be perfect, no matter the price you paid for it. There's always going to be something that was overlooked or isn't ideal for your exact requirements. Which is why Sugru might just be the rescue medicine you need.
Sugru is like duct tape had a baby with Play-Doh. It's a self-setting rubber that can be formed by hand, molded to any shape or bonded to anything, and turns into a strong flexible silicone rubber.
Anyone can use it, anyone can buy it. It's cheap, it's soft, it's resistant to a wide range of temperatures, it's waterproof and it's removable, which makes it pretty much perfect for a range of fixes, repairs and redesigns for mountain-bike applications.
It's an incredibly versatile material so the only limits are your imagination. I've used it to make chain stay protectors (or add extra coverage to too-short chain stay protectors), I've plugged stealth routing holes I have no time for; I've made new cable guides; made cable rub protectors; and fixed shoes with it. I'm sure there are many more uses for it, which is why I know keep a packet in my backpack for emergencies, much like I do with a roll of duct tape around my pump.
Sugru's mantra is 'If it's broken, fix it. If it's not broken, improve it.' Mountain bikers have to cope with often-expensive fixes so this might help ease the burden of long walks home or just those niggling issues. More so, it might help turn that nearly perfect bicycle into a mega machine.
