BB replacement 15.00, brake cable lubrication 8.00, cleaning,lubrication and adjustment of the transmission 30.00 new marathon tyre 40.00 and 3.10 probably tube all in euros. Is this a good price?
- 15€ for BB replacement sounds fair, just that in this case it should be free (if the bike ist part of the recall Brompton pays a flat fee for the work, at least they do in Germany)
- 8€ for brake cable lubrication sounds expensive. Depending on what he does exactly it may be justified or not.
- 30€ cleaning,lubrication and adjustment of the transmission: Do you have a problem with the transmission? If not: why should it be adjusted? lubrication is a 5 minute job, cleaning depends from the state of the bike. Sounds like flat fee to me and 30€ clearly on the steep side for a Brompton.
- 40€ marathon tyre: The list price for a M+ in 349 is 39,90€, the list price for a marathon green is 22,90€. Assuming it would be a M+ this price would be ok at a local shop. But keep in mind that online prices are massively lower - i.e.
~22€ for a M+ in 349 and
~15€ for a Marathon green. The question is why you need a new tire anyway if all what has happened was blowing the tube...
- 3,10€ tube: very reasonable price at a local shop, especially if it is a Schwalbe tube (which I would prefer) - same price than at cheaper online-shops and way below the list price. Kendas etc. are cheaper than Schwalbes but do not hold the air as well from my experience, therefor I'd rather avoid them if I had the choice. Still nothing to complain about with the price.
In total you'd end up with 98,10€ and what's still missing is possibly a fee for mounting tire and tube.
The initial problem that you lined out would be a blown tube and a warranty replacement of the bb. So this would be 3,10€ for the tube (taking the price from your offer) plus 10-15€ for the work of replacing it (in Germany, Spain should not be more expensive I assume). Bb would be free. So a total of less than 20€.
Depending on what you can do yourself and in which state of maintenance your bike is your offer may be expensive or justified. Depends.
