I got a turbo shortly followed by a set of rollers, exactly for the times when the kids are in bed and I can’t get out of the house.
The turbo is an Elite mag unit and then I went for the Cyclops rollers with resistance unit. Whilst it doesn’t offer the same resistance as the turbo, its still enough to do high cadence interval sessions if you want.
The rollers have kept me amused for much longer than the turbo. If you haven’t been on them before, then there’s an element of almost having to learn to ride again. Its very twitchy and engages your concentration a bit more.
But if you’re talking about ‘data’ then maybe you’re looking at turbos with PC connection? I don’t know if pricier rollers do that.
I keep going back to the rollers, but for now the turbo just sits there unused.
Oh, and budget for a fan, cos even in a cold garage or shed, you’ll sweat like its 40degrees outside.
