|... because one fell off in training. I guess the aluminium of the|
tubes is prone to wear!
|Tape and cardboard under the rear carrier|
makes an adequate (and fairly effective)
|Disassemble detached "horn". reassemble, using gorilla glue to "fix it".|
I used alignment marks I made on the mount and the tube of the "horn" to ensure I had them lined up right before I got the glue out.
|Setting up the mech.|
At this point it won't even go onto the 32t cog.
|No cable ends to hand, so another touch of gorilla glue|
will keep it all tidy.
|All present and correct. Chain freshly lubed. Hoppy now sporting a deore rear mech, and a 175mm front crankset.|
|Marginal Gains. A haircut saved me 33g|
(I know the scales say 36, but i forgot to "tare" them,
and the bag weighs 3g!)
|The mounting stub for one of my "Aero"|
horns weighs in at 78g
|the "tube" from a "horn" weighs in at 43g|
|A complete horn, with shorty grip, weighs in at|
170g. I am using two, so that is 340g heavier (!)
the effect of the "horns" is so marked, however,
that it is 340g well spent.
|Hoppy now sports a Deore M590 derailleur|
|The Altus supplied with the bike weighs in at 22g|
more, and has a more limited range, and the Deore
shifts better. I picked the Deore mech up, BNIB,
two years ago for a tenner (about $15), and this
is the first time I have used it.
|How did it go?|
This is a Strava segment for the main part of the route - from the stadium gates, round the official 100km route, and back to the stadium.
Last year's time is my "actual" time from the sportive, and correlates with my "official" time on my finisher's certificate.
This year I was a LOT faster in practice than I was for last year's actual event.
A bit of weight saved (off me and the bike), and a bit better aero, including the "horns", too
