About Seat Clamp 34.9

There are few health activities more beneficial than cycling. As well as offering an outstanding amount of burn in the legs, a good cycling session is also a good cardio-vascular workout. It's also worth noting that cycling is a virtually no-impact exercise, making it ideal for those who suffer from impact injuries such shin splints or an inflamed Achilles.

Enthusiastic bikers can often be found tinkering with their beloved machines. It makes sense to do so: for those who bike regularly, it's important to keep everything working in tip-top condition. There are a number of different factors that can affect a bike’s performance, including the tyres, wheels, brakes and - of course - the seat. (There are few things quite as grating as an uncomfortable bike seat!)

One of the key parts of the seat is the seat clamp. Fortunately, these can be easily replaced with a bit of online shopping. Size is obviously an important part of replacing the seat clamp, with seat clamp 34.9 (and a number of other sizes all available for purchase.

Costs vary, but seat clamps aren't too expensive considering how important they are to the bike in general. It’s always a good idea to double check and make sure that the seat clamp in question is compatible with the bike it’s bought for.
