Boardman’s SLR range sits in the “serious but not boutique” end of road cycling, competing with carbon race bikes from the likes of Giant and Trek that prioritise speed without going fully pro-only. The SLR 8.9 Disc Di2 takes that template and adds modern kit where it matters: electronic shifting and disc brakes, aimed at riders who want crisp performance on fast club runs, sportives and hilly routes.
Who is this for?
If you’re tall enough to suit an XL frame and you value consistent shifting under load, Di2 is the headline. Electronic gears keep changes accurate in the rain and when you’re tired, which can make long rides feel smoother and more controlled. Disc brakes bring stronger, more predictable stopping in mixed weather, and carbon construction keeps the bike lively on climbs while staying composed at speed.
- Size XL: best for riders who need a longer reach and taller stack; check your fit before ordering.
- Disc brakes: confidence on wet descents and stop-start urban sections.
- Di2 shifting: clean, repeatable gear changes with minimal adjustment.
