Across the river and into the hills & trees: last Thursday, I did a 50-km canter on my derailleur bike, hoping I might see some turning foliage. I had refreshed the bike, a ti-framed light touring Eclipse, hoping to use it Down Unda next March/April. My Raven was the reference point, especially its comfortable (for me) positioning of the bars, about 90 mm above the nose of the saddle, and its low-low gearing (15.3 gear-inches in Rohloff #1). To make the Eclipse more comfortable and better for climbing the hills of the NSW border ranges, I raised the bars about 40mms to ease the stress on my back, especially on the drops; lowered my gear ratios by replacing my 24T front granny ring with a 22T item, and swapping out my rear 11-32 cassette for an 11-34; and replaced my 700 x 32 tires with a set of 700 x 35 Marathon Supremes.
So, I was seeking out some hills, to check the effects of the lower gearing; and more generally, to see if the higher bars and wider tires made the bike more comfortable.
The Gatineau Park had been off-limits for the better part of a week, as we had just experienced a very rare "weather event", as they're called: six (!count 'em!) tornadoes in a 4-hour period, to the north and west of Ottawa, and one in the city itself. Tornadoes are not uncommon in southwestern Ontario, but very rare in these parts. One, north of Ottawa on both the Ontario and Québec sides of the river, was especially large and destructive, with hundred of homes damaged or destroyed by winds in excess of 250 km/h. Within the city itself, the urban forest took a battering, but thankfully, there were no serious injuries, and prolonged power cuts were more of a big inconvenience than anything. (Sunday before last, there seemed to be at least three times as many cyclists on the streets as usual. People had left their cars at home, as most gas stations had no power, hence couldn't sell the juice. The neighbourhood was marvellously quiet -- seemed a little like the dawn of a low-carbon age.)
Riding along the bike path in the hills, I found a hairpin bend where a micro-burst (a concentrated, violent windstorm) had knocked down large conifers and hardwoods in a patch of forest about 100 metres square. Big trees were jumbled up like a bunch of pick-up sticks, some of them snapped clean through. Sobering stuff.
At my turnaround point, all was calm and beautiful in mid-afternoon, with just a hint of the colours still to come. The hillside you see below is often a riot of orange, red and gold in mid-October.
The tweaks to my bike worked quite well. The raised bars made the seat and pedalling position much more comfortable--not quite as comfy as my Raven, though--and the lower gearing (low gear is 18 gear-inches) let me climb most of the hills (8% or so, with just one short'n'steep 12%) on the middle ring. I used my 22T granny ring a couple of times, just to see if the tiny wee thing performed as expected. It did, and my original-spec T105 front derailleur (now 15 years old) nudged it up to the middle ring as required. The 35mm Supremes measured about 33mm inflated, a couple of mm wider than the 30-31mm actual width of the previous tires. At 50-plus psi at the front and 55-plus at the rear, they were more comfortable than the tires they replaced (a Bontrager and a Marathon Racer).
So far, so good. More to come from Down Unda in March & April.
