The suspension fork is arguably the most important component on a trail and enduro mountain bike. A quality fork transforms confidence and capability on technical terrain while a poor one wastes energy and undermines control. Here are the best mountain bike suspension forks available in the UK for 2025.
Top Picks
RockShox Pike Ultimate 140mm Suspension Fork
The RockShox Pike Ultimate is the benchmark trail fork for the vast majority of riders. The Charger 3 damper provides precise compression control and the Motion Control HSC/LSC adjustment lets you tune the fork to UK trail conditions ranging from smooth flow tracks to technical, rooty loam. The 140mm travel and 44mm offset combination suits most trail and light enduro bikes perfectly.
Fox 34 Factory GRIP2 140mm Suspension Fork
Fox is the other half of the trail fork duopoly and the 34 Factory with GRIP2 damper is their answer to the Pike Ultimate. The GRIP2 four-way adjustment is among the most sophisticated available and the plush small-bump sensitivity of a well-set-up Fox 34 is genuinely exceptional. The factory tune from new is excellent for UK trail conditions.
Manitou Mezzer Pro 150mm Enduro Fork
Manitou makes excellent forks that are often overlooked in the Fox and RockShox duopoly. The Mezzer Pro is their enduro-focused offering with 150mm of travel and the impressive IFP damper. The Dorado-inspired architecture provides a progressive, supportive feel through the stroke that suits bigger UK enduro terrain particularly well. An outstanding alternative worth serious consideration.
RockShox SID Ultimate 120mm Cross Country Fork
For cross country and marathon riders who prioritise low weight and efficiency, the RockShox SID Ultimate is the go-to option. The 120mm travel and Charger Race Day damper keep the fork locked-out efficiently on climbs and responsive on technical descents. The lightest performance fork in the RockShox range without sacrificing the quality UK riders demand.
Öhlins RXF 38 M.2 Enduro Fork
Öhlins brings their motorsport suspension expertise to mountain biking with the RXF 38. The TTX damper provides a level of tune-ability that is unmatched in the industry and the sustained stroke support makes this fork exceptional on the sustained descents that UK enduro venues provide. An investment for dedicated riders, but the performance justifies the premium.
Buying Guide
Travel matching to your bike is important. Most trail bikes are designed around 130 to 160mm forks. Fitting a fork with significantly different travel changes geometry and handling in ways that may not suit your frame.
Axle standard must match your fork mount. Nearly all modern trail and enduro bikes use a 15mm thru-axle (Boost standard is 110mm width). Check your hub specification before purchasing.
Offset affects handling feel. 44mm offset forks suit most modern geometry trail bikes. Older frames designed around 51mm offset forks may handle poorly with modern shorter offset options.
Damper quality is the biggest differentiator between budget and premium forks. Low-speed compression adjustment allows you to fine-tune the fork for UK loam, clay and rock conditions.
Service intervals must be followed. Suspension forks need lower leg service every 50 hours and a full service every 100 to 200 hours. Factor in the cost of annual servicing when budgeting.
