Hatched yesterday after one too many glasses of Leffe, I committed to ride the same route today, three times, on three different bikes to see if there were any particular conclusions that could be drawn.
Typically takes about 100 minutes, a bit of up and down, mostly singletrack, rooty but not rocky, all rideable bar some steep wooden steps. Conditions under tyre were mainly dry and dusty with only a few softer patches.
First up was a rigid ss with v brakes and fairly modern 2.2" tyres with minimal grip, pumped up hard.
Next up was a geared cyclocross bike, compact chainset, barend shifters, cantis and fairly aggressive knobblies pumped up to 75psi.
Finally a rigid geared bike with mechanical disk brakes and 15 year old 1.9" tyres, again pumped up hard (notice a theme?)
The intention was to ride reasonably steadily - the purpose wasn't which bike was quickest as doubtless whatever I rode first would be - and take roughly the same time for each section.
In the interests of 'science' I will record what I consumed:
Before - left over barbecue with spicy sauce on two cheap rolls.
During each ride - a bidon of water, nothing else.
After 1st ride - salt beef sandwich, small portion of spicy tomato pasta salad, half a small bar of Dairy Milk, a can of Diet Red Bull
After 2nd ride - jalepeno chicken wrap, small portion of roasted tomato and basil couscous, half a small bar of Dairy Milk, a can of Diet Red Bull
- all three bikes were 'fit for purpose'
- each one made the route different. On the ss the temptation was to get stuck in and the v brakes and ceramic rims worked a treat in the dry. The cyclocross bike had me being a bit more selective in avoiding things with the cantis making me more anticipative when I had to brake - go into a corner a bit 'hot' and there wasn't much you could do but hope you'd come out the other side. On the disk braked bike, while I was tired, you could charge around with the knowledge that stopping wasn't a problem.
- getting your legs ripped by thorns three times over isn't fun
- I should have included a bike with suspension in the test
- I think the differences in brakes and tyres would be much more apparent in the wet or on a more technical route so might be worth repeating at some point
- it was a good way of making me go out three times!
Anyone else tried this or similar?
