I dont think any of them have lifetime warranties on the frames.
I think specialised have a lifetime warranty on their bearings or something like that, but from the people I know, they need that as they need replacing far mor frequently than others.
Your first stop for up-to-date information regarding warranty for ANY bike manufacturer should be the manufacturers website. It's not uncommon for different models to have different warranties and for companies to change these quite frequently.
Trek - Lifetime FRAME ONLY unless you buy a Session when it's 3 years.
LaPierre are a little naughty and don't publish details of their warranty which leads me to believe it's likely to be just 1 year which really wouldn't surprise me in the least. I'm sure they've come a long way but I've always found their build quality to be very hit & miss - mostly miss.
Specialized (IIRC) are lifetime but by this point I'm bored doing your searching for you (Google is your friend) so you'd be best checking direct with them
If they want to get funny about it - yes. They can refuse. Had a Trek 8900 we sold (a while ago to be fair) that we replaced the headset on (upgraded to a King) and when the frame failed (at the rear non-driveside dropout) they initially refused the claim because a 'non standard part' had been fitted.
On appeal they gave him a new frame but it took a lot of fighting. It could just be that a Jobsworth was manning the Warranty desk that day but we weren't best pleased this is why I always say to keep the original parts - just incase you do need to make a claim.
Plenty of other bike companies that offer crash replacement.
If even the bloke who helped design the Horst Link has moved onto bigger and better then perhaps it's time to admit the Horst link was great in it's day but there are better systems out there. Although, he has gone over to DW Link so you have to wonder if he's feeling quite right
Marin again Top notch warranty as a friend found out when the frame broke for the 2nd time. Mind in under 3 years not what you would expect a frame to do.
I don't think any of the top end bikes have issues regards the way their suspension works, they all just work slightly different in given conditions. But the Horst link when climbing on slippy technical stuff [Pro Pedal used on the Fox shock] you get the best traction. It doesnt react as well to big hits [2 foot+ drops] when descending at speed as well as a swingarm.
Warranty law says that you can only refuse a claim if the non standard part has directly affected the failure.
That makes more sense, but the trek wording suggests putting a sticker on the frame would be bye bye warranty...
Well despite the 10 year old whose head hit my frame this morning I don't need to claim just yet 4 brothers riding around on bikes with no brakes=asking for trouble. I thought he'd hit something sharp at first but just a massive bump from hitting the frame, Remedy 1, small child 0
length of warranty would only bother me if said frame had a bit of a reputation for cracking/breaking. if the frame breaks doing something i shouldnt ive only got myself to blame.
if i cracked a frame after 3-4 years of giving it a complete hammering id say id be happy with that.
on a different note i allways used to keep my pace fork receipts.... and current marz forks.
hope dont seem to give a shit if you have a receipt or how old it is. a mates just sent off a 5 year old rear xc hub with a broken spoke eye( after they told him to send it in and theyll take a look at it). will be interesting to see what happens.
