Better braking
Mechanic adjusting the gears
I have a Batribike 20 tricycle but am struggling to apply the rear brake effectively due to tenosynovitis in my left hand. This rarely causes trouble, except that I now live halfway up a steep hill and need to brake my trike fairly forcibly. In the last month, I have ridden the trike a lot in Holland where I had no trouble at all. Have you any helpful ideas?

Shaft drive
Mechanic adjusting the gears
Are there any shaft-drive bicycles on the market today? I know several types were developed and sold in the 1890s and 1900s.

Narrow-wide chainring
Mechanic adjusting the gears
On page 20 of the Oct/Nov issue of Cycle magazine, reference is made to mountain bike gearing ‘with a narrow-wide chainring’. I have not come across this phrase before. Can you explain?

Diabetes and energy drinks
A doctor with a stethoscope
I’ve just had my annual blood tests done. The result was a slight impairment of glucose regulation. This did not show diabetes but could increase the risk in the future. This got me thinking about the energy drink I use (SIS Go Energy). Is this okay or should I consider changing? I don’t go hard and fast on my rides, generally a steady 50 miles at around 12.5mph.

Slippery cycle path
judge's gavel and documents
I’m a member of Cycling UK and came off my bike while commuting to work. The bike slipped on moss-covered paving on a bike path as I moved aside for a jogger. I broke my left hip and did £400 worth of damage to the bike. Can I claim against the council?

Friction shifting
Mechanic adjusting the gears
After the failure of a hub gear on a tour left me stranded, I’ve decided to go back to derailleurs. I want to keep things simple so I’d like friction shifters. But I have no idea what derailleurs, chain and shifters I need to work together. I have a 68mm BB shell and 135mm spacing at the rear dropouts. I’d like the gearing range to be roughly the same as a Rohloff Speedhub (which isn’t what failed).

Wear's the problem?
Mechanic adjusting the gears
A new cassette and chain were fitted to my bike recently. After less than 300 miles, the 11-tooth sprocket is skipping, particularly under heavy load. My local shop said that it is worn and that I need another new cassette. I expected to get a lot more wear than that! They said that I should spin more in a lower gear but I want to use the highest gears. They have agreed to replace it free of charge, but is such early replacement reasonable?

Rash decision
A doctor with a stethoscope
I am a 56-year-old touring cyclist. Although I weigh 17 stone and have type 2 diabetes, I was cycling 40 miles each weekend. I have stopped riding due to worsening intertrigo. It was diagnosed years ago by a skin consultant who prescribed Timodine cream. My current GP has stopped prescribing this. Apparently, the long-term use of steroids damages the skin. I wasn’t aware and have been applying Timodine liberally for years, as it is the only substance that relieves intertrigo.

Five-speed turbo training
Mechanic adjusting the gears
Can a five-speed hub be mounted in a turbo trainer? The attachment of the gear cable on this bike enters the hub parallel to the chainstay, not axially as in some three-speeds. Also, I want to repaint the frame of my Nigel Dean as some rust is now appearing after 30 years. Do you know of an affordable way of copying the Nigel Dean decals?

650B conversion
Mechanic adjusting the gears
I’m considering fitting 650B wheels to my disc-brake equipped Planet X Kaffenback, as its 41cm chainstays mean that there isn’t room to fit a mudguard over anything other than a very narrow 700C tyre. All the 650B rims and tyres I have seen seem to be more suitable for trekking or mountain bikes. Are there 650B rims and tyres more appropriate to a road bike, accommodating tyres up to 32mm and withstanding 100psi?

Di2 destruction
Mechanic adjusting the gears
While out riding my Ultegra 10-speed Di2-equipped road bike, the rear derailleur sheared itself from the frame dropout and lodged itself in the rear wheel. On inspecting it, Madison (the UK distributor for Shimano) declared that this was not due to defective manufacture. As Shimano have stopped making Di2 10-speed derailleurs, I have had to spend £525 on an 11-speed drivetrain (rear derailleur, front derailleur, chain and cassette).

Compensation denied
judge's gavel and documents
I was thrown from my cycle by a pothole and suffered a fractured cheekbone and a damaged shoulder. I attempted to get compensation via the Cycling UK Incident Line but West Sussex Council were able to deny any responsibility as they could prove they satisfied ‘statutory requirements’. This was that the road was inspected every month and that the defect was noted and repaired within a month. One of the questions asked was: is the pothole deeper than three inches?

Tread on Armadillos
Mechanic adjusting the gears
I have Specialized Armadillo tyres on my own and my wife’s road bikes, and our Claud Butler tandem. I can boast of puncture-free riding over many miles. However, I’ve had four Armadillos that have shed their tread. I have not recorded the actual mileage but there appears to be plenty of tread left and I ride with correct pressures. My complaints to the retailer have been met with blank faces.

Oiling the gears
Mechanic adjusting the gears
I bought a new bike with a Pinion P1.18 gearbox in December 2015 and want to change the oil. Although the manufacturer states that the oil only needs changing every 10,000km or once a year, I would like to change it now. Do you have any knowledge of these gearboxes and where in the UK I can purchase the 60ml oil syringe?

Saddle repair
Mechanic adjusting the gears
The rail on my old Brooks B17 has broken. I have a similarly broken Lepper Voyager. Is there anybody who could do a repair?

Sun danger
A doctor with a stethoscope
We cyclists love to ride in shorts and short sleeves in summer. Like many long distance touring cyclists, I have picked up the occasional basal cell carcinoma (BCC). Last autumn, I ended up having three ‘spots’ removed. One was an early stage-one melanoma. Over the years, I had used skin creams – clearly not enough.

Contributory negligence?
judge's gavel and documents
In an ongoing case, a Cycling UK member sustained a brain injury when he was involved in a collision with a motorist who failed to give way at a roundabout. The insurance company admit negligence on behalf of their insured driver. They are, however, arguing that the injured cyclist was partly responsible for his injuries due to not wearing a cycle helmet. Paul Kitson explains why Slater & Gordon are resisting the contributory negligence claim.

Tyre size confusion
Mechanic adjusting the gears
Recently, I tried to swap tyres from my day-to-day road bike to a veteran bike I use only occasionally. It led me into a tyre sizing minefield. I checked your website, which told me that ISO 25-630 was a smaller diameter than 32-622. But when I tried to put a tyre from one bike, with an ISO stamp of 32-622, onto a wheel where the existing tyre was marked 25-630, it was too small. Am I missing something?

Upgrade derailed
Mechanic adjusting the gears
The front mech of my 2007 Trek Pilot 1.0, a Shimano FD-2203 triple, is getting a bit tired, with a lot of play in the main pivot. I can’t find a like-for-like replacement. I am using a 52-42-30 chainset with an 8-speed cassette. All the triple front mechs I have found are now suited to a maximum 50t chainring and, apparently, narrower chains.

Heart rate too low?
A doctor with a stethoscope
I’m struggling to get my heart rate into the target zones when I’m training. I take Propranolol 40mg twice a day prophylactic to reduce migraine. I understand it slows heart rate; my max HR has reduced and resting HR is 15-20 less than prior to taking medication. Will I ever be able to get into my zones again? I was able to reach them a few years ago when I wasn’t on beta blockers.
