Re: Crank Size Difference Help

I did a similar thing - 177.5mm nds power meter crank on a 175 ds crank. Didn't notice any difference, but I'm not normally sensitive to small changes and I think my left leg is fractionally longer anyway. My choice was purely financial - brand new, but unpopular size stages pm for £110.00. I think ...

Re: Dia-compe ENE wing shift levers

Tried the ENE DT shifters which also use the 'power ratchet' with 9 speed Shimano, but the ratchets weren't fine enough to get a reliable shift. Maybe better with fewer speeds?. If you still have the levers is it possible for you to count the clicks/measure the spool diameter/measure the cable pull...

Now using Sunrace (edit) indexed levers which give an agriculturally positive shift.

The Cycle Clinic sell unmatched drillings on those hubs for a small premium.

Re: Ergotec Customer Service

No experience, but they're probably gearing up for Eurobike at the moment.
Their contact form may be more reliable as there is little risk of your enquiry going to the spam folder.

Re: Gear cable sticking or what?

One thing I am suspicious of is that the rear derailleur is sticky, and doesn't tension the chain fully for a second or two after an upshift. I had similar symptoms to the OP when the grease in the B pivot dried out. It felt ok when articulated by hand, but was less reliable under it's own spring t...

Re: What fork

I have the Thorn 853c forks on my Spa Audax. They're a good looking (I don't like the look of the unicrown used on the Condor's), well made, lightweight fork, but they do not offer any miraculous improvements in ride quality - the original Spa carbon/alloy forks were more compliant.

Re: Non-indexed downtube shifters on 10sp

Not tried 10 speed with DT shifters, but my experience with 9 speed is that both pure friction and indexed levers work well, but the 'micro-ratchets' on the Dia Compe ENE shifters are fractionally too coarse for reliable up-shifting. YMMV of course...

Re: Spa Audax build photos

Mind you, we've had puzzles like this before. A few years back we spent ages trying to understand why the Thorn Audax frame weighs. 2.3 kg and the Spa under 2 kg. when both are supposed to be made from 0.8/0.5/0.8. What's more if anything the Thorn stays should be lighter! True. Perhaps both brands...

Re: Spa Audax build photos

I've recently built up a 54 Audax frame which weighs 58g more than a larger 56 frame which i had before (978g vs. 920g) . Are those accurate weights? They both seem on the low side to me. Sorry missed the '1' off the beginning (now edited). As to accuracy - no, not a calibrated scale, but the same ...

Re: Spa Audax build photos

If I had to guess one way or the other, I’d say the bigger frame feels stiffer.. Did you weigh the new (58) frame? I think Spa may have changed the tubing on the 725 Audax?

Re: Overinflating tyre to make rim explode

Depending on the geometry of the rim, an iwanson gauge may not always show the true picture.
The rim below showed c. 0.75mm (edit) when measured, but the reality was a lot less. Unbelievably it hadn't failed despite being paper thin, but I certainly got my money's worth (H Plus Son TB14)
