Patch Kit TT-04 The well-proven patches from Rema Tip Top have already saved many a cyclist's day. The TT 04 patch set contains eight patches and is particularly suitable for narrower tyres such as those used on road bikes or generally on sporty bikes. Ideal for all those who prefer to spend their time on the bike rather than at the side of the road and who do not want to be stopped by a puncture on the way.
