Best Turbo Trainer Riser Blocks for Triathlon Training 2026

What to Look For

Every smart trainer and turbo lifts your rear wheel or axle off the ground, which tips your bike backwards and puts you in an unnatural, nose-down riding position. A front-wheel riser block puts that height back under your front wheel so the bike sits level again — the difference shows up immediately in saddle comfort, handlebar pressure and how “real” the ride feels on longer indoor sessions. It’s a cheap fix for a problem most triathletes only notice after their hands have gone numb on a two-hour bike session.

Key Features to Consider

Universal wheel fit — most blocks are shaped to cradle a range of tyre widths so the same block works whether you swap between a road bike and a gravel or MTB.
Non-slip base — a rubberised or ridged underside stops the block skating across a hard floor or trainer mat mid-effort, especially during out-of-saddle intervals.
Storage and portability — some blocks clip onto the trainer frame itself so they don’t get lost between sessions or when the trainer is packed away.
Fixed vs adjustable height — a simple fixed block levels the bike; an adjustable or motorised unit can also add a simulated gradient, at a much higher price.

Our Top Picks

Best Overall: Elite Travel Block Front Wheel Riser

This is currently the only purpose-built, in-stock riser block on Tredz’s turbo-and-roller-accessories range — which makes it an easy recommendation on its own merits: it’s designed to work across road, gravel and MTB wheels, has a non-slip base for stability during hard efforts, and clips onto the trainer handle for storage between sessions. At £16.99 it’s also cheap enough that there’s little reason not to have one.

Best Budget: DIY Riser

Being upfront: the specialist riser-block market is small, and if you’d rather spend nothing, a stack of interlocking rubber gym-floor tiles (or a couple of thick, sturdy books wrapped in an old towel for grip) does the same basic job — support the front wheel until the bike sits level with the rear. It’s less tidy than a purpose-built block and won’t clip away for storage, but it costs whatever you’ve already got lying around the garage.

Best Premium (different category): Elite RIZER

Worth flagging separately rather than as a like-for-like riser block: the Elite RIZER isn’t a passive wedge, it’s a motorised gradient simulator that tilts the front of your bike through a real incline/decline range in sync with Zwift and other platforms, while also letting the bars steer your in-game avatar. It’s a genuinely different, far pricier category — similar in spirit to Wahoo’s KICKR Climb — for triathletes who want real physical feedback on climbs and descents rather than just a level base, at £799.99 (RRP £824.99).

Buying Tips

Measure roughly how much your specific trainer raises the rear axle before buying — most fixed blocks suit the common 3-5cm range most direct-drive smart trainers create, but check if you’re running an older wheel-on turbo.
Put the block on a trainer mat, not bare flooring — the mat’s own grip stops the block sliding even if its own base is only lightly textured.
If you switch between a road bike and a gravel or MTB often, check the block’s cradle is wide enough for your widest tyre before assuming “universal” covers it.
Don’t skip levelling on short sessions — even 20-minute turbo efforts feel noticeably better on a level bike, and it protects your saddle/handlebar pressure balance over a full season of indoor training.

Care and Maintenance

Riser blocks need almost no maintenance — wipe off sweat drips and any tyre grime after sessions so the surface doesn’t get slick, and check the non-slip base periodically for compressed or worn patches that reduce its grip. Store it clipped to the trainer or somewhere flat rather than on edge, so it doesn’t warp out of shape over time.
