These days, the majority of £600 mountain bikes come equipped with budget suspension forks. Most cost less than the price of a fork service (£80-100), so very few of them ever get much TLC. It isn’t worth paying for a service, but there are things you can do at home to help improve performance and longevity


It’s fair to say that one fork manufacturer dominates the £600 price point. SunTour forks are everywhere, and while the company also manufactures more upmarket models, its entry-level dominance is obvious.

Nearly all entry-level forks use steel rather than aluminium stanchions. They’re strong and slippery but prone to corrosion, so it’s worth following a regular service schedule.

Improve your Suntour fork

A cheap SunTour fork like this isn't worth sending off for service — but you can work on it yourself to improve its performance

This step-by-step guide is applicable to any budget fork that has no oil bath lubrication in the lower legs; fork specs can be checked online, so you can see what you’re dealing with before you crack anything open. However, the procedure for stripping a budget suspension fork is virtually the same for all brands and models.

We got hold of a used SunTour XCR for this article, something like you’d find on a Specialized Hardrock, for example. Frankly, it felt and looked terrible but, with a little love, it performed surprisingly well, proving that this task is worthwhile.

Remember, though, this guide is for budget forks only. If your fork has aluminium stanchions and/or uses air as a spring medium, this isn’t for you.
