Re: Specialized Allez: which new group set ?

That looks the same model as I brought 2nd hand about 3 years ago as a training bike for one of my daughters. It really hadn't been looked after well and I got a full Shimano 105 11sp groupset for it for a surprisingly low price in a sale. Plus the new 105 brakes had enough clearance to fit proper m...

Re: Spoke Tension Meters

Got round to calibrating it today, seemed to go OK ended up with a reasonable graph even got an equation for it Excellent work indeed. I like the equation! My calibration jig relies on a 150kg digital scale, so I'm not going to test to spoke failure. But like the idea of producing a graph for each ...

Re: Graphene lube

My last 2 chains seem to have lasted less than 2,000 miles each, less than I normally would hope for. Now if this "wonder" lube is as good as they say and it really lasts over 1,000 miles per application then £15 for the small bottle may be great value. However the cynic in me somehow doub...

Re: 20c Clinchers and other musings

20mm tyres were pretty common to race on in that era. Tubs dominated but for less important events I also used mainly Michelin tyres, 20 and 18mm! For TTs 18mm Wolber tubs were the business on narrow Wolber profiled rims, still have a pair hanging up in the shed from my wife, the Campag C Record 28 ...

Re: Greatest ever uk frame builder?

In the 1980s Columbus addressed these issues with their four tubesets of the same material but increasing weight and stiffness: SL, SLX, SP, SPX. The 'X's with internal helical ribs. I don't think I've ever seen an SPX frameset, and SP was fairly rare. I suspect that pros were happier to use the he...

Re: Witcomb?

I look forward to seeing the build pictures Brucey. The way those stay ends are domed at the dropout is really beautiful and not something I have seen before. I prefer frames without large fancy details, this one looks great.

Re: Selle SMP saddles

With SMP make use of their test service, nothing to lose.
I would not have tried such expensive saddles without such a facility.

Re: Good helmet for ventilation

I do think that some of the models marketed more for road racing are better vented, though they do cost a lot more too. Of course this may be marketing BS and appealing to trendy racer lookalikes with deep pockets. Some aero models may sacrifice cooling for marginal gains though. I get pretty sweaty...

Re: Fitting Stages/4iii crank arm to RS500 BB?

Early Stages were poor but I understand the latest model has better sealing and signal strength. The 4iiii models are fairly solid. Garmin pedals have been problematic across all three generations for a whole range of reasons. One of the most reliable options is the Favero Assioma pedals, which als...

Re: Fitting Stages/4iii crank arm to RS500 BB?

One of the easiest power meter solutions is the Garmin Vector 3 pedals. Just change pedals between bikes, only solution for some of us with older bikes where things like the Stages aren't compatible. Just be aware many power meters can be troublesome, we have first hand experience of issues with Sta...

Re: Selle SMP saddles

Has anyone here tried one or have experience of them? I've been mulling it over for a while, mainly because of the price, but I've decided to give one a try so just ordered. My main problem with saddles is that when I get them in a comfortable position as regards sit bones and a level that doesn't ...

Re: Rims for Audax Bike with Dynamo Hub

Drilling a drain hole in the rim isn't something I considered. What size are these holes normally, one each side 180 degrees apart? they are about 1mm diameter, so small that you don't see them if you are not looking for them. Next time you see a set of shimano wheels take a look. The exact correct...

Re: Rims for Audax Bike with Dynamo Hub

the archetype grey finish varies from batch to batch. I couldn't find an exact match between a 32h and a 36h grey rim; fortunately it is only obvious when the rims are side by side, not on the bike. FWIW with any deep section rim you can drill drain holes which let the water out as you ride. Some r...
