Continental Tires 181781 Editorial Review
The Continental 42mm Presta Valve Tube appears to be a popular and reliable choice for road bikes, according to customer feedback. It is a 650cc tube that is compatible with a 25x700c tire size and is ideal for wheels that are 25mm deep. The valve length is 42mm, which is long enough for easy pump attachment. The tube is well-made and of good quality, and the price is reasonable. However, there are some mixed reviews regarding the valve stem length, storage quality, and tube structure. Some customers have reported that the valve stem is too short for their bike, or that some tubes have issues with structure, which impairs pump insertion. One customer reported receiving a defective tube that had a puncture, even though it had been stored unused for a long time. Overall, the Continental 42mm Presta Valve Tube is a decent choice for a spare tube that works well with most tires, but it may pay to double-check valve stem length and inspect tubes for any defects before buying.
