Only one, as in "Watt the hell am I putting myself through this for?"So how many Watts up a 20-25% hill on a 39 x 24 at 45 - 50 rpm............approximately 44 inch. Be good to know

Depending on your terrain 80 ish is OK as a guide but pedal at a cadence that feels comfortable to you. Out on the club run I'm pedaling at 90 average - 160 max but on a longer distance hillier solo ride I'm riding at around 60-70 on average (I like to free wheel down hill so the cadence there is zero and that lower the average). I've never recorded the cadence on the commute but I like to be riding at a comfortable pace and have the spare capacity to up it, when I need too.Can anyone suggest any ranges I should be aiming for?

Years and years and years ago when I rode the track, I got to know how fast to pedal to get a 'comfortable' rythym.
As my legs got stronger and I could output a bit more power, I would naturally get the bike to travel faster. But this meant that because the bike only had one gear, I was pedaling faster.
So, the chainring was changed to a tooth or two larger for a couple of inches longer gear to bring my pedaling rate back down to where I felt comfortable. 105.
Hills though were a different matter.
There wasn't a gear on the bike ( my Pug ) that allowed me to ride at the pedaling rate I rode on the track up Gorcot hill on the return ride from Evesham.
I steadily climbed up the last 10% gradient on 38 x 23 at 70ish rpm. 9 mph, and according to CTC's PowerCalc sheet, that's 400 Watts.
So I guess 400 Watts is not beyond 10 mins of effort ( even for a fifteen year old ).![]()

BTW, it was a 48 x 16 on the track bike to keep a steady 25mph.
And before you shout...

Fitted it on the train in this morning and works a treat.
