James Dabill took control of the Scottish Six Days Trial on day two as he charged into sole possession of the lead.
A second flawless performance in a row, over the longest course of the week, ensures he holds a three-point lead heading into day three.
Welsh rider Iwan Roberts, who had shared the lead with Dabill on day one, had a day to forget, racking up 10 penalty points and dropping down to 11th.
Michael Brown and Dougie Lampkin are Dabill’s nearest competitors, with Brown in second on three points and 12-time champion Lampkin a point further back in third.
Only Dabill made it round the 107-mile route over Leanachan and Kinlochleven without a mark, with Dan Peace and Francesc Moret completing the round with just one penalty point.
Emma Bristow remains the leading female rider heading into day three, sitting in 30th overall on 28 points. She is 59 places ahead of her nearest competitor, Jess Bown, who sits in 89th place.
Wednesday’s route is a 77-miler, which includes a trip over the Corran Ferry and takes in Strontian, Ardgour and Loch Shiel.
