Re: Cape wrath to Kingsgate

Did you ever ride this route 'molzor' I am thinking of a very similar thing and would be interested to hear of your experience or at least if you found an agreeable route. I didn't! Its still on my list. Are you living in Kent and looking for a team mate? haha (Sorry for the late reply, I dont come...

Re: Gearing again

...... I dont know why they are stocking "round the world" tour de fer bikes with this gearing..... because shimano don't make a suitable product that gives you low gears on a road bike. It is as if they have a corporate blind spot. In fact things have been getting worse, in that their 'r...

Re: Gearing again

I recently went from a compact (50-34) to a lower-gear set up (44-30) for a cost of £25. 1. Take a 5703 triple crankset. 2. Remove the 50 and 39 rings. 3. Replace the middle ring with a TA 44T 130BCD, using single chainring bolts. 4. Move front derailleur down a bit. 5. Fiddle about with cable tens...

Re: Gearing again

The mech is definitely a 4703, but apparently there are two versions of this. I have checked all the routing, cleaned, regreased. new outer cable. everything. I guess, the problem really is that it will not shift up, particularly to the big ring. I can make it shift up, but this means using a tonne ...

Re: Gearing again

read teh model numebr and double-check what the chainring interval is meant to be with your mech . Compare with the interval you are using and act accordingly. Note also that the FD is meant to be used with the chain entering it at within a certain range of angles; toe in or toe out can alter the a...

Re: Gearing again

Is the stiffness only felt when the cage comes into contact with the chain and presses against it, or is it felt before then? You haven't by any chance re-attached the cable to the front derailleur on the other side of the pinch bolt? The stiffness is almost certainly just because I am forced to ov...

Re: Gearing again

all else being equal shifting force will also be increased if you move from ramped/pinned rings to some with fewer ramps/pins etc. is this the case? (there are different chainring options on chainsets from spa) Also, is the shifter/cable old, poorly lubricated, or badly routed (esp via a BB guide)?...

Re: Gearing again

Looking at the front mech in depth, there appears to be different versions of the same mech, the one they are currently selling is listed as 4703b http://chainreactioncycles.scene7.com/is/image/ChainReactionCycles/prod137772_IMGSET?wid=500&hei=505 But my one looks more like this https://i.ebayim...

Re: Gearing again

I have been playing with the height and angle of the front mech in regards to the channels. It doesnt seem to make much difference. It still requires extreme tension in the cable and a very stiff shift to make it change up. You couldnt really use it like it is. I wonder if the channels in the mech a...

Re: Gearing again

I bought a TD2 170mm 46/36/26 version, maybe this was a step too far from the recommended 50/39/30? I also got a new BB which was a shimano un55, 113mm, 68mm. my front mech does have a channel in the middle which lines up with the chain on the second ring. maybe it would help if this channel wasnt ...

Re: Gearing again

Ultimately, if you’re struggling on hills, and you want to ride hills, working to up your fitness, rather than down your gearing is the best option. If you can stand on one leg, then on the other leg, independently, that’s as much ‘strength’ as you need for cycling. Improving your fitness and muscl...

Re: Gearing again

Yep, looks like the chainline is off.

the front mech specifies 45mm, mine with this bb and crankset looks closer to 50mm.

Spa assured me that this crankset was ok with my road chainline! thats why i bought it!

How frustrating.

Re: Gearing again

WELL I bought that spa chainset but after a lot of faffing about, and a trip to the bike shop... it just wont work. Everything should be compatible, but i just dont know. Im having to put in a hell of a lot of tension to get it to shift and the shifting is really stiff. Too stiff to use really. I ha...
