Re: Touring wheelset choice

Unless the weight is removed from the braking surface thickness! Saying that, I find the rear rims wear through more quickly, presumably due to picking up more crud so maybe a thinner rim is OK on the front! The last couple of Mavics I've had have been pathetically thin, 1 - 1.1mm thick braking surf...

Re: Touring wheelset choice

Cheaper option might be to buy an Iwanson dental caliper for around a fiver and measure the rim sidewall thicknesses yourself to check how much life is left in them. Replace around 0.9mm thickness. Just in case Halfords are trying to make a sale. The gauge is also useful to have in future to monitor...

Re: Chainring orientation. Zinn says...

Can't say I've had the chain get stuck between the crank and outer ring very often, and that's despite having unshipped my chain off the big ring many times just recently as I'm having front mech issues (has to be set up to overshift or I can't get the granny-to-middle 'ring shift to work). Also ten...

Re: Post-mount brake blocks

Still got one set of brakes using these pads, on my old Dawes simply because the brake posts are too close together to allow later cantis with V-brake pads. Still hate setting them up with pad angle, reach and height varying simultaneously when the nut is slackened off. I like the holder/insert idea...

Re: Matching tyres to frame.

I'd agree, my oldest bike has a pair of 531 steel forks and the front end ride quality is way better than my other bikes, and the front wheel axle can be seen to move back and forwards over bumpy surfaces (so the fork acts mainly as a spring in the horizontal rather than vertical direction, I think)...

Re: Chainring orientation. Zinn says...

I tend to rotate my chain rings around 90 degrees when they are part worn, to spread the wear as there is noticeably more wear on the teeth which are at ~90 degrees to the crank arms after a while. The orientation of the 'rings is maintained relative to each other though, using the alignment marks o...

Re: UN55 BBs not so good anymore?

You can invariably remove the RH bearing from the RH cup in such BBs (it just takes a little persuasion), and regrease it as suggested upthread (remove inner seals, add more, better grease to central void). FWIW I have seen more than one 'RPM' BB with a broken spindle. You can just imagine the meet...

Re: Spa versus Van Nicholas titanium frames

I think tyre clearance could be an issue too. I bought some Van Nic Yukon carbon forks previously. Struggled to get anything wider than 25mm tyres in with mudguards fitted. Sold the forks again. A friend has a Spa Ti audax frameset and about 25mm seems to be the limit with decent mudguard clearance,...

Re: Best budget repair stand?

I've always rated the Tacx T3000 - have had a couple. It's simple and robust, folds up quickly and holds the Bottom bracket/down tube, not the top tube, which stops the bike swinging around when pedalling/working on the bottom half of the bike. Also gets the bike up higher than a typical stand clamp...

Re: Gear Trimming?

My guess is the front mech cable is completely slack in the small chainring position (as the mech rests on the stop screw) and the small trimming movement at the shifter is not taking up the slack/moving the mech. You may need to increase the cable tension.

Re: Dynamo failure for the second time

I remember the lights going out once when I was descending a steep hill with a bottle dynamo on. Then later the lights came back on. I believe there is some kind of voltage regulator in some systems to protect the bulb in the light? I know it's not the question, but would highly recommend using a hu...

Re: Mavic Aksium - build quality ?

A guy in our club had a set of Aksium disc wheels which made a similar tinkling noise due to loose spokes.

I've a set of non-disc Aksiums from around 2008 and they've been perfect and hardly ever needed spoke tweaking.

Re: UN55 BBs not so good anymore?

I've just removed a Token square taper unit which has been used for only 5-6 club runs. Squealing noise from the bracket noted on the last ride (77 miles, lots of hills). Removed the BB and bearings felt really rough. Traces of rust inside the non-drive-side cup so I assume water got in. Bear in min...

Re: Dawes MTBs from the 1980s

I notice that Brucey's frame has the oval 'Dawes' head tube badge.

My 1994 Mean Street had a similar badge. Not sure if that helps narrow down the date range at all but could it be a late '80s to mid-'90s frameset?
