Re: Cable pull ratio on left hand downtube shift levers

Looking promising. Thank you all for your interest and helpful comments. I checked each part of the system. No obvious problems except the lever being rather stiff, so I followed Reohn2's suggestion to put some oil into it, which has made a difference, thanks. I also sprayed the joints in the derail...

Re: Cable pull ratio on left hand downtube shift levers

Thanks all. Lots of ideas! I'm going to disassemble and rebuild this weekend with new cable (inner and outer) and without the Shift Mate, also testing whether the existing cable has resistance when disconnected from the derailleur, whether the derailleur is stiff and whether the lever is stiff when ...

Re: Saddle advice

I second the idea of sitting on and trying some other bikes - at a local club, or friends/colleagues, or even in a big bike shop. You can see what saddles feel like and if they hit the same sit bone spot. That will give you an idea where to start. Some shops will lend out some kinds of saddles, or l...

Re: Chain lubricant!

My experience is that it is a case of what you want to compromise on! For example Finish Line or Muck-Off dry lubes seem genuinely not to attract much dirt, but you have to give them time to dry before riding and re-lube often (50-100 miles depending on conditions, less in heavy rain). Whereas for e...

Re: Cable pull ratio on left hand downtube shift levers

All looks A1,cable is clamped correctly,etc. It seems to be pointing to excess friction somewhere from the lever down,check cable inner is in good order with no broken strands to snag,renew the outer. On good quality nylon ferrules theres a brass stopper/thick washer,inside to stop the linear stran...

Re: Cable pull ratio on left hand downtube shift levers

Thanks very much all for the suggestions. A few further comments: From inner ring to outer ring the lever moves through about 90 degrees with the Shift Mate installed. Without the Shift Mate it was about 60 degrees. Reading other people's experiences with similar sounding setups, I wonder whether I ...

Re: Cable pull ratio on left hand downtube shift levers

I have three different makes of downtube levers on the three bikes I have on the road at the moment. All three have triple chain-sets. I have those wonderful classic Simplex levers on one, I have Shimano Exages on another and I have the Dia-compes from Spa on the other. All work fine - each has it'...

Cable pull ratio on left hand downtube shift levers

I'm looking for a better solution to this issue. On my classic drop bar touring bike, I have a Shimano "10 speed" road triple front derailleur because that one works with the frame geometry - I tried an 8 speed (FD443 I think) and it just won't shift between middle and small rings - lookin...

Re: Brightest dynamo lamp

Beam pattern as well as overall brightness is important. B&M show pictures on their web site of the spread and pattern of their various lights (http://www.bumm.de/innovation-original/lichtvergleich-scheinwerfer.html). I have the Cyo Premium (senso plus, no reflector, auto on-off through light se...

Re: Brooks saddles – making sense of the range

Interested in reading of people retiring their old Brooks saddles. Not sure if members are aware that Brooks do offer the service whereby they will recover your saddle. In 2013 it cost me £55 incl p&p to have my titanium swallow saddle recovered - compared with £220 for a full replacement. Serv...

Re: Brooks saddles – making sense of the range

Having now done a fair few rides on this Cambium C17, I remain to be entirely convinced by it. There is no getting around the fact that it’s very firm indeed. This has highlighted an interesting thing: my sit-bones are not symmetrical. It is the right one that bears more weight on this saddle. Unfo...

Re: Handlebar position for long legged rider

....But I think moving your hands 4 or 5 inches is a lot different to shortening the stem a couple of centimetres on a drop bar bike, which some people seem to worry about I agree. However it occurs to me that such stem length changes are often made in conjunction with moving the saddle back too. O...

Re: Handlebar position for long legged rider

My reaction to Laura Laker in this picture (from a CUK email) is that she looks too far forward on the bike, but it's difficult to judge from one photo. I would have thought a shorter stem and seat farther back would have been better. Note this is a women's specific bike with steep seat angles. I w...

Re: Handlebar position for long legged rider

Back to the question about whether stems this short are bad for handling: I haven't ridden enough different bikes to be able to really compare. I have been riding with short stems for many years (for reasons as explained earlier in the thread), and I think you just get used to it. The steering is pr...

Re: Which lights for hub dynamo

I agree it's confusing. I strongly recommend B&M's Cyo range - 5 bikes in our family have been using them for several years with no failures (in my case daily for 6 years). If you head over to their own web site at bumm.de, they have a table comparing the different variants of the Cyo. Switch to...
