Re: What tourer for my wife?

Hi, You could do a lot worse than this : http://www.decathlon.co.uk/hoprider-300-womens-city-hybrid-bike-id_8307663.html Ignoring the rampant sexism, it will do a lot more than "occasional rides around town". Fabulously well equipped for the price, and the basics are also good, a French ba...

Re: mtb tyre pressure for road use

Hi, Higher tyre pressures won't help 2.25" tyres on the road, 45 and 35 psi is plenty. Any tyre with a good MTB tread will be very poor ridden mainly on road, the only upside is they will get better as you wear the central knobblies. 27.5" is really 650B, 584mm, with limited tyre choices, ...

Re: Chain Length Conundrum

Hi, Chain length is very misunderstood. Racers use the minimum because of weight and exploit the limits of the geometry of the derraileurs (which is not good for most). Conversely you can fit the longest chain possible, exploiting the opposite limits of the geometry of the derraileurs (which is not ...

Re: Inner tube sizing

Hi,

Of the marginal choice, the bigger tubes wll keep air better.

FWIW given the claim its suitable for 47mm for 32 mm I would
have gone for the smaller of the two choices, given a choice.

Re: 27.5 commuter tyre recommendations

Hi, 27.5" is just for any American dominated market. MTB wheels are 26", 700C MTB wheels are 29" and 650B MTB wheels are 27.5". No point fighting the inevitable, most Yanks have no idea that MTB wheels are in fact 559mm, not 26" in any sensible sense. Sadly again for US domi...

Re: Shwalbe Lugano tyres?

Hi,

Proper tyre pressure for 23/25mm tyres are about your weight in Kg
in psi, with a bit more rear and a bit less less front moreorless.
e.g. if 70Kg, 75 to 85 psi rear and 65 to 75 psi front.
Obviously higher for 23mm than 25mm.

Re: Minimum Tyre Pressure

I'm currently riding at the minimum recommended pressure of 70psi, both front and rear, and the ride on the bike is a bit bouncy, which also suggests that this is too high. What would be the consequences of reducing the pressures to 52psi front, 64psi rear, which are below the minimum recommended p...

Re: Butted aluminium tubes - Why?

Hi, FWIW the Youngs modulus, i.e. stiffness of a material doesn't vary much. The strength does, by various treatments. Ergo a lightweight high quality steel frame will be less stiff than a cheap steel frame. Butting allows further weight loss without compromising joint strength, and always inevitabl...

Re: 27.5 commuter tyre recommendations

Hi, IMO 650B will become more popular as a larger bike MTB size, a smaller road bike size, and a medium touring /commuter bike size and the tyre choices will become available. There are the slick Schwalble Kojaks at 35mm : http://www.sjscycles.co.uk/schwalbe-kojak-hs385-rigid-tyre-275-inch-(584)-pro...

Re: Responsive Bike

Hi,

The thread is essentially nonsense, and there is nothing to add.

Especially as its with fat tyres, it is clearly wishful thinking.

I wish I had been hastier. It's taken many years and thousands of miles to understand what now seems obvious. Hi, Please try and explain obvious, rather than "I'm now self convinced". Planing is an an extremely dubious concept, in all respects. If it was obvious, it would be, but it isn't...

Re: Tyres 32x597

Hi,

As stated in the previous post to yours, you need 3.5mm extra brake drop.
Which is easy on most old brakes with the pads in the centre of the slot.
