• Cracked Brooks saddle fixing

  What has actually broken? You can send it to brooks for repair.

• Leg length & flat pedals

  in Mechanics & Fixin' • 1 month, 2 weeks

  

  Well, you’d need to buy a set of cranks at one length and look for a replacement L crank of the other, I guess.

• Leg length & flat pedals

  in Mechanics & Fixin' • 1 month, 2 weeks

  

  Surely having different crank lengths gives you an effective raised pedal at the bottom of the cycle but a lowered pedal at the top on the shorter crank?

• Bracket for mounting pannier rack to rear brake bolt

  in Mechanics & Fixin' • 1 month, 4 weeks

  

  They don’t seem to be.
  Often, they weren’t very good and tended to fracture at the bracket after a while. Also, as bikes moved away from calliper brakes to V and discs, there is no brake bridge to use.

• Rear spacing on 2002 Cervelo P2K Single Speed Conversion

  in General • 2 months

  

  Fit the spacers and if there enough thread left to engage the axle nuts then you’re good to go. If not then you’ll need a longer axle.

• Advice Look v Shimano systems

  in Mechanics & Fixin' • 3 months

  

  The Look type pedal systems are definitely more efficient at power transfer but infinitely more impractical when off the bike than SPD.

  When I first started using clipless pedals in the early 90’s, only Look type pedals were available. As soon as SPD came out in the mid 90’s, I switched to them and have been using one version or another of SPDs on my road bikes ever since. I don’t race and I only ride the occasional sportive so I don’t care about power efficiency, only not falling on my arse when I’m off the bike. And SPD cleats, being metal, last for years. One issue is finding shoes that are more road orientated than MTB but still can take SPD cleats and a sole for walking about without being either too smooth or too lumpy. I currently have a pair of Shimano touring shoes. I think the new generation of ‘gravel shoes’ probably do quite well in this respect.

• Why is this cassette loose? As in free hub to narrow a diameter (not spacer missing)?

  in Mechanics & Fixin' • 3 months, 1 week

  

  How loose are we talking about here?
  So;
  Is it the right thickness of spacer?
  Is it the right cassette for the freehub?
  Is the lockring done up tight?
  Have they forgotten a sprocket?

• rear horizontal dropout axle locator spacers

  in Mechanics & Fixin' • 3 months, 2 weeks

  

  Whichever fits. I’m guessing single will be long enough.

• Screw on freewheel on a fixed hub thread?

  in Mechanics & Fixin' • 3 months, 4 weeks

  

  Yes, been doing it for years without problems.

• Minimum Chainring Difference between inner and outer (TA Alize)?

  in Bikes & Bits • 4 months

  

  My 130 bcd crankset has 48/39. The latter is the smallest generally available for these cranks but ISTR TA make a 38 tooth that fits. (but it might be another brand, I can’t remember) if you want to go lower.
