Re: How well do you know the road?

Question 4 on the subject of dooring seems completely wrong to me. Encouraging cyclists into the danger zone where they will be safe because drivers should - but not must - look out for them seems completely crazy. The only safe action is for the cyclist to avoid the danger area Plus I don't underst...

Re: Of a peaked cap with mesh insert in peak?

A google for golf visor throws up some coloured plastic options which might be useful. Plus being a hatless brim they could potentially be rotated to jaunty angles despite a helmet

You'll might look a prize turnip but, as the old saying goes, if the sort of cap thing fits......

Re: Home built disc wheels

Not strictly homebuilt as construction took place in a lab but it was a Sunday morning** 'skunkworks' special so still hand made Materials (x2 where appropriate for front and rear wheels) were Campag Shamal rim, Mavic large flange hub, some aluminum sheet, some polystyrene, carbon fiber cloth, resin...

Re: What went wrong?

some SRAM cassettes have one screw and two plastic spigots which align the sprockets. If the screw backs out in service, it usually means the cassette lockring wasn't fully tight, and the sprockets were moving around. cheers Interesting that this is not unheard of then As far as I noticed the casse...

Re: What went wrong?

My roadside diagnosis was foreign object injestion because I thought I felt play in the freehub. Something like undergrowth sucked into the gap twixt hub and cassette. Hence trying to lube it In the shed the freehub span freely as soon as the cassette retainer was loosened but there no obvious reaso...

Re: What went wrong?

No rattle when shaking the wheel, I couldn't really spin the cassette enough to hear anything

What went wrong?

Somewhat of a rhetorical question as I've already fixed it but the issue was something I've never experienced before. I was riding along yesterday - my usual off-road fare of gravel, mud, sand etc - when it became apparent that my freewheel was in trouble. In perhaps a mile it went from draggy to ne...

Re: Car speedometer accuracy.

Modern systems are all programmable so it's worth querying the calibration with the dealer if it's miles out. Could be you have a wheel option package that's not been programmed into the cars brain On mine (BMW) the 'analog' dial is over actual speed by 3% give or take but the hidden digital display...

Re: Removing a chain quick-link without tools

Tie the shoelace into a loop around the quick link. Then use a stick/Allen key to twish the loop tight Spanish windlass style.

Re: conception vs execution; shoes can be a problem

I've done a few like that too. Interestingly I've also got a habit of destroying normal footwear too. I certainly pull up hard on the pedals when sprinting, enough to regularly unclip the back foot nearly vaulting me over the bars. Back in the day I measured roughly 55/45% front/back force standing,...

Re: Weird tube failures

Well I managed a ride today with no issues I dawned on me that the tubes might reveal something. Inspection showed that all valves had come adrift side to side not fore and aft. Also I didn't notice any valve cant but the wheels are, for MTB rims, deep section so valve skew is limited The tyre itsel...

Weird tube failures

In the last 4 days I've been for 3 rides and had 3 inner tube failures. All have failed the same way - the valve stem has detached from the tube leading to rapid deflation As far as I can see the rim tape (Velox) is ok although it is a little petrified. I had a good finger poke and escaped without c...

Re: Both brakes off one lever

Would a cyclocross style interrupter lever be more usable?
Or maybe a aero bar lever used upside down in the end of the drops activated with the palm?

Re: A cheap way to clean your chain

I use water, a scrubbing brush and washing up liquid for regular maintenance. For a really deep clean I use a mix of diesel and Machine Mart concentrated parts washer solution in the megasonic cleaner. Solution is heated in the microwave For serious concretion, such as laddo next doors chain, I use ...

Re: Weak leg on ebike

I don't know this for a fact but I would imagine that an averaging function is applied in the more expensive torque sensing systems. Motors prefer constant drive but pedal input is far from smooth. If I was designing the system I would certainly average over a 360 crank rotation. Probably dealer swi...
