Review: Set güzel taktım gayet iyi fiyatıda uygun
Review: Great replacement for hydraulic brakes. No hassle to fit & pleasantly surprised by the quality. Everything you need comes in the box including bolts & brackets. Only minor niggle is that the front cable could have been a little longer while the rear cable was too long!! Easy to cut down the rear, not so easy to add a bit to the front!! All in all very good value for money 🙂
