Audax / Re: "Selling" an event

The aim of advertising is to sell more units, the same units at a higher price, or to increase the satisfaction of those who buy, or have bought.

Curiously, part of the satisfaction of Audax is the way it repays research. So the experienced tend to be attracted by the obscure, and the difficult. The entry fees are very low by sportive standards, so they probably aren't a factor to newcomers. Older people on fixed incomes may notice them more.
The Knowledge / Re: Avid BB5 or BB7 Disc Brakes?
« Last post by Brucey on Today at 06:45:47 am »
I'd agree with the above.   I'd also note that the wear life of the brake pads is not brilliant in BB5 or BB7 calipers in that the brake pads are held off the disc by springs, and the springs sit within the thickness of the friction material. This means that Avid's recommendation is that the pads are replaced after only about one and  bit mm is worn off them (from a friction material  thickness of ~2.4mm) .

If BB5 (road) are set correctly with new pads, and the FPA/barrel adjuster are used as necessary there is enough arm movement such that the pads will each wear about 2mm or so before you run out of arm travel.  However if the brake is not set correctly to start with, or you somehow  manage to wear the pads about twice as much as normal, the arm will run out of travel  in a somewhat abrupt manner; the arm just hits an (invisible) end stop.

So with BB5 road, it is not at all a bad a idea to mark the caliper body with some blobs of paint so that you know if you are about to run out of arm travel or not. I think that BB7 do not have quite the same characteristic.

BTW it could be worse; Tektro managed to make thousands of calipers in which the end of the arm travel was signalled by a 'click' sound as the balls inside the calipers ran off the end of the ramps, leaving you with..... nothing.... :o


Audax / Re: Never mind the blizzards, it's the spoke nipples!

Thanks Whossthewheel...... that's worth knowing. I tend to make 28 spoke wheels s that is the number of holes iny dynamos.

Having made one fashion faux Pas, the fact that yellow and purple is clearly the colour of the season was reinforced when I got in last night.

Belstedly, my Ride London acceptance magazine had arrived in the post and the person pictured on the front cover in sporting a resplendent purple and yellow cycling jersey.

I can definitely live with that, but your observation is appreciated.
Bizarrely, I was at an event tonight at the V&A and at the networking drinks afterwards I got invited to an engineering event on Thursday where some science boffin is giving a talk on spokes.......seriously, never saw that coming, me at an engineering event! With my reputation? What were they thinking?
Anyway, I'll ask if it makes any difference.

it won't make any difference it is purely aesthetic... provided the converging spokes don't prevent you from accessing the valve with the pump.
It can be a problem on a 36 spokes wheel, as space between spokes is tight

Is there any functional difference between using the outer pad adjuster and the cable barrel adjuster?

If you adjust using the pad adjuster, you've always got the full throw of the caliper lever arm available to move the pad. If you adjust using the cable adjuster, you are using up the lever throw.
After enough cable adjustment, you'll either hit the end stop, or pull the cam over the top, in either case losing braking force.

If the pads adjust both sides, the pads only have to move 2 x the running clearance. If the pad only adjusts one side, the pad has toove the running clearance, plus however much you've worn off the non-adjustable pad. Since the power of the brake is directly related to the ratio between how far the lever moves and how far the pads move, and a single-sided brake caliper has to allow for pad wear, a brake with 2-sided adjustment can be made more powerful than one with single sided adjustment.

Should you be using bar end shifters rather than STI/Ergo, BB7 Mtn plus V-brake levers like the Tektro RL520 are significantly better than BB7 Road and regular drop bar levers.
Folders / Re: Brompton Headset Replacement.

Correct size spanner - don't know which but Brompton are buggers for using unique parts so it wouldn't surprise me if it was unique. A long drift or headset cup remover. Punch to remove the crown race or a specific tool. Hammer. Crown race setting tool. Headset press.

Like Raleigh Grifters, Bromptons suffer from flaring in the head tube with the lower cup working loose eventually. IIRC Rogerzilla once suggested a way to tighten the head tube if it's enlarged using a dot punch.

Rides and Touring / Re: Kings Cross to Portsmouth

Sightseeing, it depends how far you want to ride, if the weather is good a ride up Portsdown Hill is worth it for the views, there is a lay-by opposite the Churchillian pub which is home to the famous Mick's Burger van (home of the Monster Burger and good for any variety of fried thing in a bap and tea).

If you want to go a bit further afield head up to Broad Halfpenny Down (opposite the Bat and Ball, sort of in Hambledon) and see the former home of English cricket, then on to Butser Hill (the second highest hill in Hampshire) followed by a pleasant ride back through the lanes via Old Winchester Hill (22nd) before testing your brakes on Portsdown Hill (a measly 26th).

If the weather is against you then I recommend a day at the dockyard mooching around the old boats but do mind your head.

The Old Customs House is in Gunwharf Quays and you may be pursued by a security guard onna Segway if you ride your bike in the wrong manner etc etc and, as Johnny Faro says, there are a few granite sets to negotiate, not to mention the middle aged, moneyed types shambling around the area.

To get to the pub you need to go into Gunwharf through the pedestrian only archway just to the left of the road access to the carpark, walk/ride through the arch, dodge the Segways and drunks and head in a straight line towards the harbour, The Old Customs House is on your right about halfway down.
