The Lezyne Saber Levers are superb for the job and, combined with having a 15mm wrench, they are ideal for the Brompton. I always carry them when I commute on the Brompton.
I made the decision to try out a new tyre brand and snapped up a Panaracer Crosstown at a discounted price of £15.99
The tyre has the reflective sidewall, a decent tread pattern and claims to be puncture resistant. It is still heavy at 400g, so not ideal for racing.
