Just as is the case behind the concept of the outboard BB, which may be flawed, but for other reasons. Alas, I have yet to find a way of attaching it to my Brompton, but at least I’ve been able to make use of my much-neglected, entry-level, near-vintage hybrid, and maintain my cycling-legs, without getting frozen, drenched or bedraggled. For finer adjustment, you can have your fingers tight or loose – that’ll give an additional range of a quarter to a third of a finger width.

However, you need to remember to centralise the brake and fit the cable so that the brakes are snug but not binding (ideally, you will have noted where the cable was secured previously).For example, conducting a botanical survey by bicycle of a disused railway line that has been proposed for development to a cycleway, could not be more appropriate. I’m afraid that I think triathlons are probably beyond me, even if in a moment of weakness I end up getting a bike and taking to the roads. I found the very thought of cycling up those hills after a days work to be too demoralising, so I gave up. It is advertised as the ‘ 20/24″ Wheel Adapter‘, so you would be forgiven for thinking that it would be too short to enable the roller to meet a 16″ wheel.
