Re: Expert advice on choice of front derailleur, please.

Just picking up on your comment about the BB length: I have recently fitted a Spa TD-2 on my tourer, and with a 116mm First Components DX-30. The chainline is spot on (between 44 and 45mm) when tightened up to 35Nm with a torque wrench. I had ordered a 113mm BB initially but this was definitely too ...

Re: Smaller wheels for touring.

One thought on your 2.5mm vs 4mm clearance question: actual widths of tyres vary from brand to brand and also depending on the rim width. For example, I have Schwalbe Marathon Supreme 37-622 tyres fitted on two bikes. On an LX17 rim (internal width 17mm) at around 4 bar, this tyre measures 33.5mm wi...

Re: Questions on a Genesis Vagabond built

I installed a 24/34/46 TD-2 triple on my tourer recently. I am using a 116mm BB (First Components) and it is perfect. The chainline is between 44 and 45mm, the inner face of the right hand crank has a few mm clearance, and the inner chainring is between 1 and 2 mm from the chainstays. The chainstays...

Re: Likely to damage crank or BB with overtightening?

The longer axle BB arrived from Spa this morning (kudos to Bobby, I spoke to him yesterday morning and he got it out the same day). Stripped out the shorter one and replaced it. The smaller torque wrench arrived during the week, and I used this when mounting BB and cranks. I learned that 40Nm is act...

Re: Likely to damage crank or BB with overtightening?

Everything feels OK when I ride it up and down the street but it seems to me that I cannot do the crank up even as tight as I could get it with a 200mm hex wrench (which has been my standard practice for many years), before either the crank rear face or the inner chainring touches the frame. Only y...

Re: Likely to damage crank or BB with overtightening?

Thanks all. I had a look this morning, and I can see no visible damage to anything. I did realise immediately what had happened and took the crank off again, so that will have helped avoid damage. I also checked in case the shop had sent me a shorter BB than specc'ed - sorry to doubt you Spa it is ...

Re: Noisy Brooks saddle

Ok, rather bizarre question; I have a noisy Brooks saddle. I have used the Brooks Saddle treatment to no avail as did tightening the bolt. Doesn’t seem to sag down to the seat post so no obvious physical reason. As it’s just had a replacement bolt fitted by Brooks, I doubt it’s a mechanical fault. ...

Likely to damage crank or BB with overtightening?

Hi, Hope someone has some insight here. I wonder how likely it is that I have damaged my crank or bottom bracket axle. Story below ... I've just fitted some Spa TD-2 triple square taper cranks along with a First Components DX-30 113mm sealed cartridge bottom bracket, as recommended by Spa. I'm using...

Re: 165 crank sets

I have a pair in my shed. I have 160mm as well. Spa XD-2 triple cranks - no chainrings - suitable for 7-8-9 speed and very good. Easy to get chainrings for too. I bought them when experimenting with shorter cranks but went back to the 170mm ones which I have ridden quite a few thousand miles on: htt...

Re: Changing tyres to road tyres

Another tyre to look at is the Schwalbe Marathon Supreme, and these would be good if you want to stick with a wider tyre to suit wider rims. I have two bikes with the 37x622 (700c) size and they roll nicely, have pretty good puncture resistance, are comfortable and are fine for a bit of light off-ro...

Re: Catalyst pedals, Flat pedals, Foot Position, Knee Pain

Plus one for cleats moved back. In my case to position the ball of my foot maybe 10-15mm in front of the pedal axle, certainly made a difference for me. I would suggest caution with having feet angled in or out with SPD. That was a key ingredient in my fairly serious knee problem a few years ago. So...

Re: Knee discomfort on turbo trainer

Continuing the saga ... thanks everyone for your comments and suggestions. I got the new tyre - 28mm instead of 37mm- and installed. Yes, it makes a difference, subjectively about 1 gear's worth, hence reducing the uphill effect. I also experimented with how tight I had done up the fixing bolt on th...

Road....130/140 bpm with no knee pain Turbo ..100 bpm with knee pain If I have got that right, its an obvious mis-match, and I think it must mean that you pedal differently on the turbo compared to the road, which you are used to. You don't carry round a lot of "spare" muscles so you can'...
