Beautiful weather here all weekend, cool starts but calm winds and sun out!
Had a couple of things to do first thing saturday so missed the group rides. Headed out instead with Dean and Matt. Dean coming to the end of a winter of cross country running, beginning his tri season training and Matt just back from Tenerife so it wasn't going to be easy! Meeting them at 10 and Dean needing to be back around 12, meant me blagging them into doing Pencombe hill (so I had a longish climb to play around with my PWM data!), followed by a fast A road dash back to town to get back in time.

I had to dig a little to hold wheels
on the way out (pushing 300W at times just to keep contact!),
Pencombe went ok, holding 300W on the steep start, easing off to recover at 200W before the next kicker at 400W. I then started to suffer from a stitch so had to sit and spin it out for the remainder at around 200W. Was a good test of the legs, which felt fine, but I think I need to work on some active recovery as I was blowing pretty hard at the top even after taking it easier to try and shake the stitch! We had to take a bit of a detour (due to a closed road) but once we got to the A road home it was a good blast back. Rediscovered my nerves at speed cornering on non-dry roads,
losing contact @35mph (but an effort on the kicker afterwards caught and passed them!), I was feeling stronger at this point and did
a couple of pulls
on the front back towards town.
Looking at the data now my cadence sensor has 'spikes' to 250rpm but otherwise the
cadence data is very steady, much better than it was
prior to the PWM? Any ideas? Same sensor.
Great ride and a good test (exactly what I needed)
If only in the wet, it is probably just the compound, do they stop squealing after the initial braking?
Noise from braking (wet or otherwise) is, as Solid pointed out, an issue with the pad compound, contaminants or a combination of the two.
Noise when not braking is a pad rub issue or something unrelated like I found with my squeaky hub seals for example.
Bleeding them won't fix either of these things and is only worth doing if the lever has lost feel because you are squashing bubbles of air when you apply the brakes.
Bought the Shimano
funnel and
oil/bleed kit from my LBS (only £15.50 for both, not that bad really!). Performed the
mini-bleed from Epic and much of the noises have gone. I only noticed one tiny air bubble, but equally some of the oil I added filled the system so it may have just been a little low? Did a loop around the block and it was soundless... Equally the weather/roads were dry when it's been mostly ok...
Didn't ride in today (-4 here this morning with untreated roads like an ice rink!) but I'm sure the rain will catch me tomorrow/later in the week for a real test. Fingers crossed it was just a bit low on fluid and is now sorted!
As much as I get wet, I don't feel wet....if that makes sense. The gabba jersey has this wet suit like quality about it. But make no mistake, when I get home it's soaking wet!
Lots of the modern technical materials are similar to merino (or even have some blended in) for that very reason - retaining warmth even when wet!
9/10 for the trolling, keep up the good work.
No matter how much you try to keep the rain out if you're out in it long enough - it'll find a way in.
That's it, I don't think he's trolling, just the way some of the comments come across make it sound like it. Almost coming across as thoughtless, uneducated and almost condescending. It comes across as baiting. I've given up trying to understand the implications of most and just deal with the facts.
This time of year without the rain we're generally wearing windproof layers to retain warmth. When it rains the ambient temperature usually rises so the additional layers we're wearing, combined with the additional 'insulation' that a wet outer layer provides, produce lots of condensation. When the weather is generally 'wet' (and not as cold) we wear less and thinner layers, reducing the condensation.
Obviously if you're riding easier, you're producing less sweat, moisture and less heat, leading to less condensation. I've found it's such a fine margin between being waterproof (enough to stop wet coming through) yet retaining enough breathability to allow any moisture out. I find it much easier to dress to stop the weather coming in (waterproof/windroof/thermal) and then tailor my efforts to maintain the status quo inside. Much of the time that means I'm overdressed late morning when starting out early, so I'll always wear layers easy to strip (eg arm warmers under a thermal jersey rather than a long sleeve jersey) and those with vents/zips.
