Choosing the right chainsaw guide bar isn't just about length — it's about matching the bar to your saw, your chain pitch, and the work you're actually doing. Too short and you're limiting yourself; too long and you're fighting the saw on every cut. Get it right and the difference in performance is immediate.
We've compared all three bars in our Chainsaw Bars collection so you can make a confident, informed choice.
1. Stihl 12-inch Rollomatic E Guide Bar | 3/8P 0.050 44DL · £65.68
The Stihl 12-inch Rollomatic E is the compact specialist. At 30cm with 44 drive links, it's designed for precision work in tight spaces — pruning branches, limbing, and light yard maintenance where a larger bar would be unwieldy. The Rollomatic E design optimises oil distribution along the bar, reducing wear and keeping the chain running cooler, which means a longer service life even under regular use.
This is a genuine Stihl part, built to exact factory specifications, so you get a perfect fit and full confidence in compatibility with supported Stihl models. The 3/8P pitch and 0.050" gauge are standard for smaller Stihl saws.
Specs: 12" (30cm) · 3/8P pitch · 0.050" (1.3mm) gauge · 44 drive links · Genuine Stihl
Best for: Homeowners, gardeners, and anyone doing light pruning or limbing with a compact Stihl saw.

2. Rotatech 15" Chainsaw Guide Bar & Chain Pack for Husqvarna | .325" 1.5mm · £58.37
The Rotatech 15" Bar & Chain Pack is the standout value proposition of the three. At £58.37 you're getting both the guide bar and a matched saw chain in a single pack — everything you need to get back cutting immediately. Rotatech is a trusted name among arborists and professional tree surgeons, and the hardened bar rails are built to withstand the demands of daily professional use.
The 15" length sits in the versatile mid-range — capable enough for firewood processing and felling smaller trees, yet manageable enough for extended use without fatigue. Compatible with a wide range of Husqvarna models including the 133, 136, 137, 140, 141, 142, 154, 234, 235, 238, 240, 242, 246, 254, 257, 261, and 340.
Specs: 15" · .325" pitch · 1.5mm (0.058") gauge · 64 drive links · Includes matched chain · Fits Husqvarna
Best for: Husqvarna saw owners wanting a complete bar and chain replacement in one purchase. Arborists, tree surgeons, and serious enthusiasts.

3. Stihl Genuine 25-inch Rollomatic Guide Bar | Part 3003 000 5231 · £133.10
When the job demands serious reach and power, the Stihl Genuine 25-inch Rollomatic Guide Bar is the tool for it. At 63cm, this is a bar built for felling large trees, milling timber, and any application where a shorter bar simply won't reach. As a genuine Stihl component (Part 3003 000 5231), it's manufactured to the same exacting standards as the original equipment — which matters both for performance and for maintaining your saw's warranty.
The Rollomatic design ensures consistent oil flow across the full length of the bar, which is critical at this size — inadequate lubrication on a long bar accelerates wear significantly. Always verify compatibility with your specific Stihl model before ordering.
Specs: 25" (63cm) · Genuine Stihl Part 3003 000 5231 · Rollomatic design · For large Stihl models
Best for: Professional loggers, foresters, and serious users felling large trees or milling timber with a large-format Stihl saw.
