Rebuilding a Campag ergopower
Rebuilding 11 speed Campag ergopower shifters… the only official video shows the earlier model and only the RH shifter, while its the left ones that seem to go. I’ve got quite good at it, now I’ve got the special hooked tool you need to attach the springs, although it’s always a complete faff. Grease gets everywhere and then it always seems to be that I’ve put the downshift lever on at 90 degrees to the way it should be. Still, I’ve brought some dead ones back to life, and that’s quite a saving these days, and quite a sense of satisfaction!
a genuine 20 x 1 3/8 or 37
a genuine 20 x 1 3/8 or 37-451Oh no, I had a Raleigh Twenty with 451 sized wheels about a decade ago. Almost impossible to find tyres. I ended up with a pair of Shwalbe Duranos that fitted, and were good, but they were the only 451 tyres I could find. As for rims, forget it.
Apparently Japanese ‘mini velo’ bikes use this tyre size, but they’re rarely found in the UK. Good luck!!
Robert Davis’s 1993 book
Robert Davis’s 1993 book “Death on the Streets: Cars and the mythology of road safety” addressed exactly this and prompted him to set up the Road Danger Reduction Forum, which is still in existence:
You can find the book here:
LFGSS (London Fixed Gear &
LFGSS (London Fixed Gear & Single Speed) is very good, but you’ll be expected to set up a profile and contribute to other forums before selling stuff at friendly rates, not maxing out your profit. They’re not only about fixies despite the title.
BikeRadar has a cycle sales forum, that used to be very lively.
Finally, CTC has a good forum focusing more on the touring and practical side of cycling (so probably not ideal for your Synapse).
Ebay will take over 12 1/2 percent, so be aware of that, and for shipping a bike you’ll probably need to use ParcelForce Oversized, which will cost around £35 or more.
I’ve been doing that for
I’ve been doing that for years. I’ve an old steel frame that will only take a 23 at the front and a 25 at the rear, no problems whatsoever. A more modern alloy frame takes 25 at the front and 28 rear with guards. All works perfectly well. If anything, it slightly sharpens up the steering by steepening the steerer, but it’s pretty marginal. Go right ahead, you’ll save frontal area and a bit of weight with a narrower tyre and the rear takes the majority of the weight anyway so a bigger air volume there makes sense.
Spa Cycles are probably using
Spa Cycles are probably using the ‘old’ size measure used still by a few manufacturers – like Colnago – of giving a size which is the seat tube centre to centre. A 52 in Colnago is about a 56 in most other bikes.
What the geometry comparison referred to elsewhere shows is that the Elan will feel a bit longer, but with a slacker head angle and longer seat stays, it will also feel calmer and more relaxed.
As for the seat post question, you can correct the seat-bars position with a setback seatpost or a shorter/longer stem. More exposed seatpost will mean a more comfy ride in my experience. It’s what I notice most when riding an old steel bike, the short exposed seatpost is quite rigid and you feel the thumps from the back wheel more.
Try wider rims first, the
Try wider rims first, the difference in comfort between a 25c on a 15c rim and a 25c on a 19c rim is massive! And you won’t mostly need a new bike for that.
Since 11 speed came along,
Since 11 speed came along, you can’t buy internal parts for Campag ergopower shifters, even though they’re completely serviceable with a couple of special hook tools:
Your Potenza shifter is Powershift, which means it’s not compatible with Ultrashift 11 speed Campag shifters (Chorus, Record, Super Record)… and not compatible with Athena 11 speed Powershift which uses a slightly different pull ratio. Here’s good info on compatibility:
http://www.velotech-cycling.ltd.uk/campagnolo_faq.shtml
Your best bet is to buy a second hand Potenza shifter or one with a problem and try to make one good one out of two duds. It’s fiddly but perfectly doable with a bit of practice.
It should do, I have wheels
It should do, I have wheels with 11 speed Campag and Shimano cassettes and find they are interchangeable without even adjusting the cable.
My Garmin is connecting fine
My Garmin is connecting fine with Mac Catalina (10.15.7). Try syncing the Garmin to your phone directly, as I explained in the other thread.
My Garmin 520 plus uploads
My Garmin 520 plus uploads rides to my phone using the Garmin Connect app. It’s either automatic or I hit the ‘sync’ command and it uploads in a few seconds.
Garmin Connect is set up to sync with Strava automatically via the web. There’s no need to plug it into a computer, except for upgrading the software/maps from time to time.
Could be, the average car in
Could be, the average car in the UK is parked 96% of the time, according to the RAC Foundation. That sounds like people really don’t much like driving, but they don’t yet feel able to completely free themselves from car ownership…
The correct answer is, don’t
The correct answer is, don’t use big-big, it overly stresses the chain and increases wear on the chainrings and cassette. You should make a habit of dropping into the small ring about 4-5 cogs from the lowest on the cassette.
That said:
1. have you checked the rear mech hanger alignment? You say you changed it, but even a new one can be improperly aligned.
2. Did you change the front mech height after fitting the compact cranks? it should be 2-3mm above the chainring teeth.
3. If you’re using big-big a lot, you may have worn the angles of the chainring teeth so that it’s allowing the chain to drop in reverse.
4. Did you shorten the chain when you put on the smaller cranks? Incorrect chain tension can cause all sorts of problems with chain drop.
5. Pedal forwards not backwards. The freewheel is there so the wheel can go round when you stop pedalling, not so you can pedal backwards ;))
Wellgo M142 are very light
Wellgo M142 are very light (236g / pair) and compact. I have a set on my commuter that are 10 years old and still spin beautifully. There’s even a grease port. Bike-Discount had them recently when I wanted a new pair for a spare bike:

Reading Pete’s post, and then the comments below the line, I am more than happy to stick with my rim brakes 😀Me too, even carbon rim brakes seem simplicity itself – and stop well enough for me. Going is my problem, not stopping
