Re: DIY headset fitting with G/C clamp?

Yep - I've used mallet and wooden-block type methods, go carefully and check you're hitting it in straight - no problem I did it on the floor, put some wooden boards under the top of the seat-tube/bottom bracket (depending on which side I was doing!), then rested the head-tube end on a stool. I adju...

Re: Are 32 spokes enough for a 26" touring wheel?

Interesting. I wonder why they chose not to make it 36 hole, given all the reasons why? theres a number of bolts in/near one flange. Or maybe it was designed for places you cant get 36h rims? i suspect the latter; the point being that if your rim fails you'd want to be able to build your rather exp...

Re: Are 32 spokes enough for a 26" touring wheel?

If you did have a 36h rim fail, wouldn't it be possible to wire up a 36h Rohloff or equivalent to a 32 rim somehow, by skipping a hole every so often? Maybe, but it would surely not be as strong as a 32 rim on a 32 hub. Once you start down this line it seems that you get into a massive quagmire tho...

Re: Are 32 spokes enough for a 26" touring wheel?

if their is a range (and we agree that there is) it's obviously be better to have the stronger wheels, unless you're concerned about the £1 cost of the extra spokes, or indeed their mass (minus the four extra holes in the rim and hub) Disagree. It would depend on the liklihood of a wheel ever being...

Re: Are 32 spokes enough for a 26" touring wheel?

The same argument could be used for a 28 spoke wheel instead of a 32. Or a 24 instead of a 28. But 4/28ths is larger than 4/36ths, so the difference in strength might be more siginificant. A 4-spoked wheel is stronger than one with none at all. (I'm not necessaily suggesting that wheel strength inc...

Re: Are 32 spokes enough for a 26" touring wheel?

Perhaps if you subjected 32 and 36 scientifically to some tests there would be a small range at which the 36 holds out when the 32 fails ...BUT, when you actually ride your bike, the forces the wheel experiences will be well below that threshold, and in the case of taking a big hit then they will li...

Re: Are 32 spokes enough for a 26" touring wheel?

the touring market seems to be driven by demand for stupidly over-engineering machines It's about the much greater inconvenience of getting it fixed agreed, i'd sooner have a bike that's a few hundred grammes overwieght, that one that breaks. Sensationalist! And a few hundred grams!? That's rich......

Re: Are 32 spokes enough for a 26" touring wheel?

Get them done with good quality spokes and good rims and I bet they will be fine. My understanding is that 32 hole rims are internationally more available than 36 anyway, in case you ever need to get a new rim built onto the hub In view of your other comment, keep in mind that just as one bike marke...

Re: Novel derailleur problem - your thoughts?

As has been said, you're using a top-swing front mech at the moment; getting a bottom/conventional-swing mech might lower the cage enough to solve it. (Perhaps you can find someone willing to let you borrow a mech to see if it works? (sorry, I don't have any spare conventional-swings at the mo...)) ...

Re: Setting reach for flat bars

So you buy, what...3 or 4 stems till you get it right?. Why not just purchase one of those Look time-trial stems that move forward/back and up/down, would be as cheap/cheaper than several stems with more utility to boot. If you're talking about the Look Ergostem then that retails at about £150. Las...

But whose elbow-to-fingertip do they use? Robin's?

Or do you mean they stick an extra 5cm onto the length of the bike for drop bars in that size range?

(Though the question does remain...):)

Re: Setting reach for flat bars

Of course it will also depend on the length of the saddle, the height of the bars, the type of riding, etc., etc. It can still be the best starting point for most people whilst not being exactly correct for the most of people. That's averages! We have to start somewhere, especially when setting up a...

Re: Setting reach for flat bars

It makes perfect sense, thanks.

That would probably put the bars at about an-elbow-to-fingertip-plus-5cm-from-the-nose-of-the-saddle... :)
